Transcript: Seeing Sound
The name of the show appears in colourful letters on an animated sky. It reads "TVO Kids Power hour of learning. Teacher edition."
The caption changes to "Today's Junior lesson: seeing sound."
Laura says WELCOME TO
TVOKIDS
POWER HOUR OF LEARNING.
TODAY'S JUNIOR LESSON:
SEEING SOUND.
A caption reads "Junior 4 to 6. Teacher James."
James is in his forties, with short gray hair and a beard. He wears a blue T-shirt.
He says HELLO. WELCOME TO
THE TEACHER POWER HOUR.
I'M TEACHER JAMES AND
I AM SO GLAD YOU'RE HERE.
TO GET THE MOST
OUT OF OUR TIME TODAY,
THERE'S A FEW THINGS
YOU SHOULD GET YOURSELF.
A FEW OF THE EXPERIMENTS
THAT YOU SEE,
YOU CAN ACTUALLY DO AT HOME,
EITHER NOW OR LATER.
YOU'RE GONNA WANT
SOMETHING TO WRITE WITH
AND SOMETHING TO WRITE ON.
A PEN, PENCIL, MARKER IS FINE.
SAME WITH SOME PAPER,
A NOTEBOOK.
AND IF YOU HAVE SOME
OF THESE THINGS AROUND,
FOR NOW OR LATER,
THAT WOULD ALSO HELP.
He shows a list and says SO, SOMETHING LIKE PLASTIC WRAP,
A BOWL OR CONTAINER,
SALT OR SOME OTHER POWDER,
A LASER POINTER,
SOME TAPE,
AN ELASTIC BAND, A BALLOON,
A PHONE OR DEVICE
THAT PLAYS MUSIC,
A SPEAKER OR AN EARBUD,
AND MAYBE YOU WANT TO GET, LIKE,
A DRINK OR A SNACK HANDY.
TODAY, WE'RE GOING
TO LOOK AT SOUND.
OR SHOULD I SAY LISTEN TO SOUND?
WELL, YES, NO.
YOU'LL SEE.
NOW, WE TALKED ABOUT GETTING
OUR MIND READY TO LEARN,
BUT DID YOU KNOW
THAT ASKING QUESTIONS
IS ONE WAY YOU CAN REALLY
ENGAGE YOUR MIND
MUCH MORE WHEN YOU'RE LEARNING.
WHEN YOU LEARN SOMETHING NEW,
IT'S NOT THE END OF SOMETHING,
BUT IT SHOULD BE THE PROMPT
TO ASK MORE QUESTIONS.
IT GETS YOUR MIND
PROCESSING IN SOME WAYS.
I'D LIKE YOU, RIGHT NOW,
TO TRY TO WRITE DOWN - IF YOU'VE
GOT YOUR PENCIL AND PAPER -
WRITE DOWN THE FIRST TWO
OR THREE QUESTIONS YOU CAN THINK
OF TO DO WITH SOUND.
NOW, TO HELP YOU,
YOU MAY HAVE SEEN SOMETHING
LIKE THIS BEFORE -
A 'Q CHART'.
He shows a chart with question words and says NOW, IF WE TAKE THE MOSTLY
'W' WORDS OVER HERE...
OVER HERE,
AND THEN ADD THAT TO
ONE OF THE STEMS AT TOP,
THAT BECOMES THE
START OF A QUESTION.
YOU DON'T NEED TO
COPY THIS DOWN OR ANYTHING,
BUT IF YOU'RE WATCHING THIS
ON RECORDING LATER
OR HAVE ONE OF THOSE TVS
WHERE YOU CAN DO THAT,
MAYBE YOU JUST WANNA
PAUSE IT RIGHT NOW
AND USE THAT TO HELP YOU TO
COME UP WITH SOME QUESTIONS.
SO, NOW THAT MAYBE YOU'VE GOT A
QUESTION OR TWO ABOUT SOUND,
LET'S LOOK AT A PROBLEM.
He grabs his phone and says I'VE GOT A DEVICE HERE
THAT CAN MAKE SOME NOISE.
IT'S GOT A SMALL
SPEAKER UP THERE.
BUT IF I WANT TO LISTEN TO IT,
AND SAY I DON'T HAVE EARBUDS
OR I WANT MORE
PEOPLE TO HEAR IT,
IT'S NOT GONNA BE
TERRIBLY LOUD OR CLEAR.
SO, OTHER THAN ATTACHING THIS
TO SOME KIND OF SPEAKER
OR AMPLIFIER, WHAT CAN WE DO?
WHAT SORT OF THINGS DO YOU
THINK YOU MAY EVEN HAVE
AROUND YOUR ROOM OR
YOUR HOME RIGHT NOW
THAT COULD DO THIS?
KEEP THIS QUESTION IN YOUR MIND,
AS YOU SEE HOW THIS CHALLENGE
IS GONNA BE ANSWERED
ON
SCIENCE MAX,
AS THEY TRY TO FIND
THE LOUDEST SOUND.
An episode of "Science Max" rolls.
A group of young scientists appear doing a series of science experiments.
Phil is in his thirties, clean-shaven and with short curly dark blond hair. He wears gray trousers, a blue T-shirt and a yellow lab coat.
Phil says HAVE YOU EVER DONE
A SCIENCE EXPERIMENT
AND WONDERED WHAT IT WOULD BE
LIKE IF YOU DID IT BIG?
I HAVE.
(LAUGHING)
Phil appears under the water, in a skydiving chamber and on a trolley.
He says WHOA!
(SCREAMING)
MY NAME IS PHIL
AND I TAKE YOUR EVERYDAY
SCIENCE EXPERIMENTS
AND DO THEM BIG.
THIS IS
SCIENCE MAX:
EXPERIMENTS AT LARGE.
The logo of the show appears. It's a black and yellow triangle with an exploding element inside and a blue sign across that reads "Experiments at Large."
Voices shout SCIENCE MAX!
Clips from today's show roll.
Phil says TODAY'S
SCIENCE MAX
IS ALL ABOUT SOUND.
WE BEND THE POWER
OF SOUND TO OUR WILL
BY MAKING THE
LOUDEST SOUND WE CAN.
He says to a girl scientist WAIT A MINUTE.
A SUBWOOFER?
She says SUBWOOFER.
Phil says MAKE CORN STARCH MUD DANCE,
GLASSES BREAK,
AND THINGS VIBRATE.
Sal is in his thirties, clean-shaven and with short side parted dark blond hair. He wears glasses, jeans, an orange shirt and a brown tweed blazer.
Sal makes a floatie vibrate and screams.
(SCREAMING)
Phil says IT'S THE SOUNDS OF SCIENCE,
TODAY ON
SCIENCE MAX:
EXPERIMENTS AT LARGE.
Very quietly, Phil says GREETING SCIENCE
MAXIMITES AND WELCOME TO...
CAN YOU HEAR ME?
GREETINGS SCIENCE MAX...
YOU CAN'T.
HOLD ON A SECOND.
He turns up the TV volume and says GREETINGS, SCIENCE...
YEAH, THAT'S MUCH BETTER.
GREETINGS, SCIENCE MAXIMITES
AND WELCOME TO
SCIENCE MAX:
EXPERIMENTS AT LARGE.
TODAY, WE'RE GONNA BE
TALKING ABOUT SOUND.
SOUND IS ALL AROUND US.
WE USE IT EVERY DAY,
BUT WHAT IS IT REALLY?
SOUND IS ENERGY.
LET'S SAY THAT THIS IS THE...
THAT THIS...
He pulls down a projection screen and it rolls back up.
He says NO, STAY.
STAY. OKAY...
He stretches a spring across the screen and says THAT THIS SPRING IS
THE SOUND OF MY VOICE.
WHEN I MAKE NOISE, IT TRAVELS
AWAY FROM ME IN A WAVE.
ONE AIR MOLECULE VIBRATES
THE NEXT AIR MOLECULE,
VIBRATES THE NEXT
AND IT LOOKS LIKE A WAVE,
AND WHEN THERE'S
A LITTLE BIT OF ENERGY
THE WAVE DOESN'T MOVE VERY MUCH.
SCIENCE.
BUT WHEN THERE'S A LOT OF
ENERGY, THE WAVE MOVES A LOT.
SCIENCE!
WHAT DO WE DO-- WHAT DO...
WHAT DO WE DO...
TO MAKE SOUND LOUDER?
He plays the show's theme song on his phone and says THIS IS THE
SCIENCE MAX THEME SONG,
BUT IT'S NOT VERY LOUD,
BECAUSE THE SPEAKER ON
MY PHONE ISN'T DESIGNED
TO MAKE SUPER LOUD NOISES.
SO, WHAT WE'RE GOING TO DO
IS FIND WAYS TO MAKE
THE VOLUME OF THAT SONG
AS LOUD AS POSSIBLE.
HERE IS ONE WAY.
TAKE A PHONE PLAYING SOME MUSIC
AND PUT IT IN A GLASS.
MAKE SURE THE GLASS
IS EMPTY, OF COURSE.
(MUSIC PLAYING LOUDER)
He puts it in and out of the glass and says HUH?
AND SUDDENLY, IT'S A LOT LOUDER.
(MUSIC PLAYING QUIETER)
(MUSIC PLAYING LOUDER)
WOW!
(MUSIC PLAYING QUIETER)
(MUSIC PLAYING LOUDER)
WHY THIS WORKS
IS ONE OF THE THINGS WE'RE
GOING TO BE LOOKING AT TODAY.
SO, WHAT'S WHAT WE'RE
GONNA DO TODAY
ON
SCIENCE MAX:
EXPERIMENTS AT LARGE -
WE'RE GONNA LEARN HOW
TO MAKE SOUND LOUDER,
AS LOUD AS WE CAN.
BUT I'M GONNA NEED
AN EXPERT TO HELP ME.
He throws a lab coat on and enters a portal.
He says OH! I KNOW! MIKAELA FROM
THE ONTARIO SCIENCE CENTRE.
SHE'S VERY SMART.
ALL I NEED TO DO IS GO TO
THE ONTARIO SCIENCE CENTRE
AND SEE IF SHE'S BUSY.
He slides down a slide on the other side and says AH!
Mikaela is in her twenties, with long straight brown hair in a ponytail. She wears black jeans, a purple top and a white lab coat.
She says PHIL! ARE YOU OKAY?
Phil says YEAH! MIKAELA!
IT'S GOOD TO SEE YOU.
Mikaela says NICE TO SEE YOU TOO.
Phil says THAT WAS WEIRD.
I WAS WONDERING IF YOU
COULD GIVE ME A HAND
WITH AN EXPERIMENT?
Mikaela says OH! I'D LOVE TO. YEAH.
Phil says IT'S A SOUND EXPERIMENT.
Mikaela says SOUNDS AWESOME.
Phil says RIGHT ON!
OKAY! WE'LL TAKE THE PORTAL.
WE'LL GO BACK
TO SCIENCE MAX HEADQUARTERS.
Mikaela says OH! WE GET TO TAKE
THE PORTAL! COOL!
Phil says HAVEN'T YOU TAKEN
THE PORTAL BEFORE?
Mikaela says NO, DON'T YOU REMEMBER?
IT WASN'T WORKING LAST TIME.
Phil says OH! WELL, IT'S...
Mikaela says IS IT WORKING?
Phil says FIXED THIS TIME.
YEAH, NO, IT'LL BE GREAT.
TRUST ME. HERE WE GO.
They pop up in a warehouse.
Mikaela says WHOA.
WHAT'S GOING ON, PHIL?
IS EVERYTHING OKAY?
Phil says USUALLY WHEN I COME THROUGH
THE PORTAL,
I LAND ON SOMETHING OR
SOMETHING FALLS ON ME OR...
Mikaela says NOT TODAY!
Phil says IT'S YOUR LUCKY DAY.
I GUESS SO.
Mikaela says SAFE LANDING! NICE!
Phil says SAFE LANDING!
HIGH FIVE! ALL RIGHT!
SO, LET'S GET STARTED...
Mikaela says OKAY, COOL.
(CRASHING)
Phil bumps into a big pile of plastic crates, they all fall and make a loud noise.
Now they stand behind a table with an empty glass.
Phil says THIS IS THE EXPERIMENT I WANT
TO MAX OUT TODAY, MIKAELA.
I KNOW.
PRETTY IMPRESSIVE, RIGHT?
NO, NO. HOLD ON.
(LAUGHING)
Phil says OKAY.
SO, I TAKE MY PHONE
AND I PLAY SOME
MUSIC ON MY PHONE.
(MUSIC PLAYING QUIETLY)
He puts the phone inside the AND...
(MUSIC PLAYING LOUDER)
Phil says IT'S LOUDER!
Mikaela says HEY! CHECK IT OUT!
Phil says RIGHT?
Mikaela says PHIL, YOU'VE JUST MADE YOURSELF
A RESONANCE CHAMBER.
Phil says A RESONANCE CHAMBER!
VERY NICE.
Mikaela says A RESONANCE CHAMBER
IS WHAT WE SAY
WHEN WE'RE TRYING TO DESCRIBE
HOW THE SOUND IS AMPLIFIED.
SO, IF THE SOUND IS COMING
IN FROM ONE DIRECTION,
IT'S BOUNCING AROUND,
NOT REALLY LOSING ENERGY,
SO WHEN MORE SOUND
COMES IN THAT'S AMPLIFIED,
WE HEAR IT A LOT LOUDER.
Phil says THAT'S COOL. SO THAT'S
WHAT I WANT TO DO...
HOLD ON. LET ME TURN THIS OFF.
THAT'S WHAT I WANT TO DO TODAY.
I WANT TO MAX OUT AS MUCH
SOUND AS WE CAN GET
OUT OF THIS
SCIENCE MAX
THEME SONG...
Mikaela says OH! I'M SO EXCITED
Phil says WHICH IS TOTALLY AWESOME.
SO, WHAT ELSE CAN WE DO
TO DO THAT?
Mikaela says WELL, THERE'S A COUPLE
OF AVENUES, I'M THINKING.
DO YOU WANT TO TRY
SOMETHING WITH ELECTRICITY
OR WITHOUT ELECTRICITY?
Phil says BECAUSE WITH ELECTRICITY, WE'RE
TALKING SPEAKER SYSTEMS AND...
Mikaela says YEAH.
Phil says RIGHT.
SO, WHY DON'T WE DO
NO ELECTRICITY FOR NOW
AND THEN WE CAN JUMP
TO ELECTRICITY
WHEN WE FEEL WE'VE EXHAUSTED
EVERYTHING THAT NON-ELECTRIC?
Mikaela says COOL!
SO, I WAS THINKING WE COULD TRY
TO MAKE A MEGAPHONE,
BECAUSE IF WE
HAVE A LOT OF SOUND,
WE COULD, YOU KNOW,
FUNNEL IT IN ONE DIRECTION
AND THEN IT'LL BE LOUDER.
Phil says OKAY, YEAH!
Mikaela says WHAT DO YOU THINK?
Phil says SO, THE MEGAPHONE'S
PRETTY EASY TO MAKE, RIGHT?
WE CAN JUST USE-- IN FACT,
WE COULD USE THIS PIECE
OF PAPER, RIGHT?
Mikaela says YEAH! LET'S TRY IT.
She makes a cone out of the paper and says WHAT DO YOU THINK?
Phil says I THINK IT'S VERY MEGAPHONEY.
SCIENCE-TAPING IT UP.
OKAY, READY?
OKAY, TURN IT ON.
(MUSIC PLAYING QUIETLY)
I'LL PLAY IT.
AND... DOESN'T SOUND...
He points the megaphone at her and says BUT WHAT IF I DO THIS?
(MUSIC PLAYING LOUDER)
Mikaela says HEY! THERE IT IS!
I LOVE THAT SONG.
Phil says OH, YEAH?
YOU HEAR IT?
Mikaela says YEAH! OH, I HEAR IT.
OKAY!
(MUSIC PLAYING LOUDER)
Phil says SO, THAT WORKED
PRETTY WELL! SO...
Mikaela says YEAH, IT WORKS.
WORKS WELL.
Phil says SO, OKAY...
SO THIS IS PRETTY EASY, RIGHT?
YEAH.
Phil says MEGAPHONE?
Mikaela says OH, YEAH!
Phil says SO, WHY DON'T WE MAX THIS OUT?
WHY DON'T WE MAKE
A GIANT MEGAPHONE
AND SEE IF IT MAKES
A BIG DIFFERENCE?
Mikaela says I THINK IT WILL.
He says over the megaphone SOUNDS GOOD!
LET'S GET STARTED.
WAHOO!
The Science Max logo appears under a magnifying glass.
A high-pitched voice says MINI MAX!
(BANGING)
Phil now bangs two trash can lids together and says ALL SOUND IS VIBRATION,
BUT IT'S REALLY HARD...
(CRASHING)
IT'S REALLY HARD TO LEARN
ABOUT THAT VIBRATION
IF YOU CAN'T SEE IT.
I MEAN, SOUND IS
INVISIBLE, RIGHT?
WELL, HERE'S A WAY
THAT YOU CAN MAKE SOUND VISIBLE.
ALL YOU NEED IS
SOME PLASTIC WRAP
AND SALT AND A BOWL.
JUST A REGULAR BOWL.
AND AN ELASTIC LIKE THIS.
SO, WHAT YOU DO IS YOU
TAKE THE PLASTIC WRAP
AND CUT OFF A PIECE
JUST LARGE ENOUGH
TO FIT OVER THE BOWL
AND THEN USE THE ELASTIC
TO WRAP AROUND THE BOWL
TO KEEP THE PLASTIC TIGHT.
POUR SOME SALT ON THE BOWL
AND THEN WATCH THIS.
He gets closer to the bowl and says in a loud voice HELLO!
VIBRATING SALT!
THE PLASTIC WRAP IS STRETCHED
TIGHT OVER THE BOWL
MAKING IT LIKE A DRUM,
A DRUM THAT'S VERY SENSITIVE
TO SOUND VIBRATIONS.
YOUR EAR WORKS THE SAME WAY.
THAT'S WHY WE CALL IT
AN EARDRUM.
THE VIBRATIONS FROM MY VOICE
MAKE THE PLASTIC WRAP VIBRATE
AND THAT MAKES THE SALT DANCE.
BUT THERE'S MORE!
LET'S MAX THIS OUT.
THIS IS A CHLADNI PLATE
AND WHAT IT IS, IS JUST A PIECE
OF METAL ON A PLATFORM
THAT VIBRATES UP AND DOWN
TO A FREQUENCY,
WHICH I CAN PROGRAM
WITH THIS DIAL HERE.
AND WHEN THE SOUNDWAVES
VIBRATE THE PLATE,
THEY CAN INTERACT IN WAYS
THAT MAKE THE SAND FORM
INTERESTING PATTERNS.
TAKE A LOOK.
(HIGH FREQUENCY TONE)
He pours salt on the platform and says THE SOUNDS THAT I'M GENERATING
VIBRATE THE PLATE,
MAKE IT MOVE LIKE A WAVE,
BUT WHEN THE VIBRATIONS REACH
THE EDGE OF THE PLATE,
THEY BOUNCE BACK
AND INTERACT WITH THE OTHER
WAVES GOING THE OTHER WAY.
THE WAY THESE WAVES INTERACT
AT DIFFERENT NOTES
IS WHAT CAUSES THE SAND
TO MAKE
THESE DIFFERENT SHAPES.
SO, THIS IS GREAT,
BUT YOU KNOW WHAT?
WE CAN MAX IT OUT EVEN MORE.
MAXING IT OUT EVEN MORE!
(PITCH GETTING HIGHER)
AHH!
(PITCH GETTING HIGHER)
OKAY! THAT'S ABOUT AS MUCH
AS I CAN TAKE OF THAT. OH...
James says WELCOME BACK.
SO, WE CAN SEE THAT WHEN SOUND
HAS A CHANCE TO RESONATE,
IT CAN GET LOUDER AND FULLER.
IF WE WANT TO MAKE
A PHONE PLAY LOUDER
OR PERHAPS GET MORE
SOUND OUT OF EARBUDS,
WE'RE GONNA NEED SOME TYPE
OF RESONANCE CHAMBER.
FOR THIS, WE NEED AN ENCLOSED
SPACE AND A SMALL EXIT,
SO THAT SOUND CAN
BOUNCE AROUND INSIDE
AND THEN PRODUCE THE RESONANCE.
THINK OF IT A BIT LIKE,
YOU KNOW,
A GUITAR OR A UKULELE HERE.
THE SOUND CAN
BOUNCE AROUND INSIDE
AND IT'S GOT
THE MATERIAL OF WOOD
AND THEN IT'S GOT THE SMALL HOLE
WHERE THE SOUND
CAN THEN COME OUT.
AND, YOU KNOW, SO, THE LARGER
THE RESONANCE CHAMBER,
THE MATERIALS, ALL CHANGE THE
QUALITY OF THE SOUND THERE.
NOW, WHAT KIND OF
QUESTIONS DO YOU HAVE?
DID YOU ASK HOW
A MEGAPHONE WORKS?
OR WHAT WOULD HAPPEN
IF THE MEGAPHONE WERE OF
DIFFERENT MATERIAL?
DID YOU ASK, "SHOULD I MAKE MY
OWN DRUM OF PLASTIC WRAP
"AND WITH A BOWL AND SOME SALT
OR SOMETHING TO SEE THE SOUND?"
WELL, THE ANSWER IS
YES, YOU SHOULD.
I'VE GOT...
AND I'VE GOT THAT HERE NOW.
I'VE TAKEN A BOWL
AND INSTEAD OF SALT,
I'VE GOT SOME ORANGE
DRINK CRYSTALS ON TOP OF IT.
AND LET'S SEE SOME SOUND.
OKAY, SO, I'VE GOT
THE POWDER SET UP.
I'VE MADE KIND OF A DRUM.
NOW, IF I JUST MAKE SOME NOISE,
YOU KNOW,
WITH MY LIPS HERE, JUST LIKE...
(BLOWING RASPBERRY)...YOU DON'T SEE ANY EFFECT.
BUT IF I ADD, SAY, A BIT MORE
RESONANCE TO THAT,
LIKE, SAY, MY VUVUZELA HERE...
I'M GONNA PLAY THIS
AND I'M GONNA KEEP THE BELL
OF THAT ACROSS HERE.
SO, YOU'LL KNOW IT'S
NOT THE WIND OR ANYTHING
MOVING THESE AROUND.
LET'S OBSERVE WHAT HAPPENS.
He plays the vuvuzela and the salt starts moving out of the bowl.
(HORN BLARING)
(HORN BLARING)
James says WHEN WE WERE
DOING THAT JUST NOW,
I WAS PLAYING THE VUVUZELA
AND THE VIBRATIONS FROM THAT
WERE THEN CAUSING
THE BOWL TO SHAKE
AND THAT WAS MAKING
THE PLASTIC WRAP SHAKE
AND THAT WAS MAKING THE DRINK
CRYSTALS ON THERE
START TO KIND OF
BOUNCE UP AND DOWN,
LIKE IT WAS A TINY TRAMPOLINE
AND THEY STARTED TO MOVE OFF
BECAUSE I HAD IT TILTED UP.
SO, WE CAN SEE THAT SOUND CAN
HAVE-- EFFECT THINGS PHYSICALLY
AND IT'S NOT JUST THIS
OTHER THING WE HEAR,
BUT IT IS PART OF
THE PHYSICAL WORLD ITSELF.
NOW, IF YOU STARTED TO
MAKE YOUR OWN AMPLIFIER,
YOU MIGHT WANT TO SEE WHAT KIND
OF CHANGES YOU CAN MAKE
IN THE MATERIAL YOU USE,
WHETHER INSIDE OR OUTSIDE,
THE SIZE AND SHAPE OF THE
RESONANCE CHAMBER,
THE SIZE AND SHAPE OF
THE EXIT FOR IT.
ALL THOSE VARIABLES,
IF YOU ALTER THEM,
IT WILL HAVE SOME
EFFECT ON THE SOUND.
NOW, IN KEEPING WITH GOING TO
THE NEXT LEVEL WITH DESIGN
AND TRYING TO CHANGE THINGS UP,
LET'S CHECK IN ON HOW THE QUEST
FOR THE LOUDEST SOUND
IS GOING WITH
SCIENCE MAX.
Phil says SO, MIKAELA
AND I ARE ON A QUEST
TO MAKE
THE LOUDEST SOUND WE CAN.
THE FIRST STEP IS
TO MAKE THINGS LOUDER
WITHOUT USING ELECTRICITY.
WE'VE LOOKED AT
A RESONANCE CHAMBER
AND NOW WE'RE GOING TO MAKE
A LARGE MEGAPHONE.
SOUNDS CAN BE AMPLIFIED
BY BOUNCING SOUNDWAVES
AROUND IN A SPACE.
WHEN I PUT MY PHONE
INTO THE GLASS,
THE GLASS ACTS AS
A RESONANCE CHAMBER.
THE SOUNDWAVES BOUNCE
AROUND INSIDE THE GLASS
AND THEY COMBINE AND STACK
ON TOP OF EACH OTHER.
THIS MAKES THE SOUND LOUDER.
RESONANCE CHAMBERS ARE USED
BY MUSICAL INSTRUMENTS,
LIKE AN ACOUSTIC GUITAR.
THE WOODEN CHAMBER BOUNCES
THE SOUNDWAVES AROUND
AND THE SOUNDWAVES
BUILD ON EACH OTHER
TO MAKE THE SOUND LOUDER.
A MEGAPHONE BOUNCES
SOUNDWAVES AS WELL.
INSTEAD OF GOING OFF
IN ALL DIRECTIONS,
A MEGAPHONE MAKES THE
SOUNDWAVES
ALL GO IN ONE DIRECTION.
THAT'S ONE OF THE REASONS
WHY A MEGAPHONE
MAKES SOUNDS LOUDER.
BUT ONLY WHEN IT'S
POINTED AT YOU.
SO, WILL A BIGGER
MEGAPHONE WORK BETTER?
SO, WE'VE MADE
A LARGER MEGAPHONE,
WHICH IS EXACTLY THE SAME THING.
YOU JUST TAKE A SHEET
AND YOU ROLL IT UP,
EXCEPT OUR SHEET WAS
PLEXIGLAS COVERED IN PAPER,
AND WE'VE TAPED IT
TOGETHER SO IT STAYS,
AND THE IDEA HERE...
Mikaela says OH, YEAH. BIGGER MEGAPHONE.
WE'RE GONNA VIBRATE EVEN MORE
OF THE AIR INSIDE OF HERE
AND HOPEFULLY,
THIS THING WILL BE LOUDER.
Phil says OKAY, SO YOU'RE READY TO
TRY IT WITH THE PHONE?
Mikaela says YEAH!
Phil says I THINK FIRST,
WE SHOULD TRY IT WITH
OUR VOICES, THOUGH.
Mikaela says OKAY!
They stand at a distance from each other,
Mikaela says through the megaphone HEY, PHIL, WHAT'S YOUR
FAVOURITE SEASON?
Phil says AWESOME! I CAN TOTALLY
HEAR YOU! THAT'S AMAZING!
Mikaela says CAN YOU REALLY?
Phil says AND IT WOULD BE FALL.
NAH! SUMMER!
UH, SPRING?
Mikaela says THINK ABOUT IT.
Phil says ANYTHING BUT WINTER.
SO, THE MAXED-OUT
MEGAPHONE WORKED,
BUT WE STILL HAD TO
TRY IT WITH MY PHONE.
OKAY.
Mikaela says ALL RIGHT.
(MUSIC PLAYING QUIETLY)
(MUSIC PLAYING LOUDLY)
Phil says YEAH?
Mikaela says OH, YEAH!
(MUSIC PLAYING LOUDLY)
OH, DEFINITELY.
He moves the phone further from the megaphone and says HOW ABOUT NOW?
(MUSIC PLAYING QUIETLY)
Mikaela says NO, NOT SO MUCH.
NOT SO MUCH.
Phil moves the phone closer to the megaphone.
(MUSIC PLAYING LOUDLY)
Mikaela says OH, YEAH!
(MUSIC PLAYING QUIETLY)
Mikaela says NO, NO.
Phil says SO, THAT IS A...
THAT WAS COOL... GREAT EXAMPLE OF
NON-ELECTRICAL AMPLIFICATION.
Mikaela says THAT'S RIGHT.
Phil says AMPLIFIED THE SOUNDS.
NO ELECTRICITY.
OKAY! HIGH FIVE!
Mikaela says SWEET!
Phil says ALL RIGHT.
Now a neon sign appears that reads "Sal's Science Shop."
Sal says COME ON!
MAKE SOME NOISE!
(JAZZY SAXOPHONE MUSIC PLAYING)
Sal dances and says WELL, HOW DO YOU MAKE NOISE?
WELL, TO KNOW THAT,
YOU GOTTA KNOW YOUR SOUND.
HEY!
(JAZZY SAXOPHONE MUSIC PLAYING)
ALL SOUND IS VIBRATION.
(GUITAR STRUMMING)
He grabs a guitar and says HERE! TAKE A CLOSER LOOK.
YOU SEE? WE'VE GOT...
He falls over the counter and says WHOA!
OKAY, LET'S TRY THIS AGAIN.
ALL SOUND IS VIBRATION.
(NOTE SOUNDING)
Sal says THE STRING OF
THIS GUITAR VIBRATES,
WHICH VIBRATES
THE AIR AROUND IT,
CAUSING THE SOUND THAT YOU HEAR.
YOUR VOCAL CORDS
VIBRATE IN YOUR THROAT,
CAUSING YOU TO MAKE A SOUND.
(GUITAR STRUMMING)
AH!
(GUITAR STRUMMING)
AH!
(GUITAR STRUMMING)
AH!
LA-LA-LA-LA-LA-LA-LA
He pulls out a floatie and says LOOK AT THIS THING!
LOOK AT THIS THING!
SEE HOW
IT'S SHAKING BACK AND FORTH?
IT'S VIBRATING.
THINGS THAT
MAKE A HIGH SOUND...
(DINGING)...
He plays a tringle and says THEY VIBRATE FASTER.
He makes the floatie vibrate more and says VIBRATING REALLY FAST.
WAH!
THINGS THAT MAKE A LOW SOUND
VIBRATE SLOWLY.
(TUBA PLAYING)
He moved the floatie really slowly and says AH!
HIGH NOTE!
(DINGING)
VIBRATING FAST.
FAST!
(RINGING)
In a low pitch, he says WHOA!
(GUITAR STRUMMING)
LA!
FAST VIBRATING!
(LOW NOTE SOUNDING)
He bangs a gong.
He says SLOW!
AND NOW YOU KNOW YOUR SOUND!
(RINGING)
He bangs the gong again and breaks it.
(CRASHING)
The caption changes to "Max Fax!"
Phil stands behind a fish tank and says EVERYTHING HAS A RESONANCE -
A NOTE THAT IT VIBRATES BEST AT.
LET'S SAY THIS
FISH TANK IS, WELL,
ANY CONTAINER WHERE SOUND
WOULD BE VIBRATING
AND THE WAVES OF WATER
ARE ACTUALLY WAVES OF SOUND.
NOW, NORMALLY,
SOUND WAVES WILL BOUNCE AROUND
INSIDE THE CONTAINER,
OFF THE WALLS,
AND GO BACK AND FORTH LIKE THAT.
AND HOW FAST I MOVE
THIS PIECE OF WOOD
IS THE FREQUENCY
OR THE NOTE THAT WE'RE PLAYING.
I COULD VIBRATE
THIS WOOD VERY FAST
AND MAKE A HIGH NOTE.
I COULD MOVE THIS PLANK VERY
SLOW AND MAKE A LOW NOTE.
AND THE WAVES JUST BOUNCE
AROUND INSIDE THE CONTAINER.
BUT THERE'S A SPEED
I CAN MOVE THIS PLANK
WHERE THE WAVES STOP
GOING SIDE TO SIDE
AND SUDDENLY GET TWICE AS BIG.
THE WAVES BOUNCING
OFF THE SIDES OF THE TANK
ARE MEETING THE WAVES GOING
IN THE OTHER DIRECTION,
BUT WHAT WE END UP SEEING
IS PEAKS OF THE WAVES
NOT MOVING SIDE TO SIDE,
JUST GOING UP AND DOWN
LIKE YOU SEE HERE.
THIS IS THE RESONANCE
FREQUENCY OF THIS CONTAINER.
SO, LET'S MAX THIS OUT.
SAY I HAVE A WINE GLASS
AND I WET MY FINGER
AND I RUB IT
AROUND THE RIM.
(GLASS RINGING)
IT VIBRATES AT A CERTAIN NOTE.
THAT NOTE IS THE
RESONANT FREQUENCY
OF THIS WINE GLASS.
SO, WHAT WOULD HAPPEN
IF WE WERE TO PLAY THAT NOTE
BACK TO THIS WINE GLASS
REALLY, REALLY LOUD?
(NOTE RESONATING)
He uses and amplifier to amplify the note and AND YES, THIS IS SOMETHING
YOU SHOULD NOT TRY AT HOME.
THIS NOTE MAKES
THE GLASS VIBRATE THE MOST.
FINDING THE PERFECT NOTE
THINGS VIBRATE BEST AT
IS GREAT FOR
MUSICAL INSTRUMENTS,
BUT IT'S NOT GREAT FOR
THIS WINE GLASS.
THE SOUNDWAVES ARE CAUSING
THE GLASS TO VIBRATE A LOT
AND BECAUSE THIS GLASS
IS DELICATE,
IT CAN ONLY VIBRATE SO MUCH
BEFORE IT BREAKS.
(NOTE RESONATING)
The glass cracks and breaks.
(CRACKING)
(NOTE RESONATING)
THE VIBRATIONS WERE SO STRONG
THAT THE GLASS LITERALLY
SHOOK ITSELF TO PIECES.
(LAUGHING)
He says SCIENCE!
He takes off his earmuffs and says SORRY-- SCIENCE!
OH, WAIT.
He takes off his earplugs and says SCIENCE.
James says SO, UH, I LIKE TO THINK
THAT, AFTER THAT,
YOU MIGHT HAVE SOME MORE
QUESTIONS YOU MIGHT WANT TO ASK.
MAYBE SOMETHING LIKE,
"HOW CAN SOUND BREAK GLASS?"
OR ABOUT HOW A
RESONANCE CHAMBER WORKS.
LET'S THINK BACK TO THE EXAMPLE
WITH HOW IT FOCUSES SOUND.
WELL, LET'S LOOK AT THIS
INSTRUMENT HERE -
A JAW HARP.
IF YOU JUST PLUCK THE METAL...
(PLINKING QUIETLY)...YOU DON'T REALLY
HEAR ANYTHING.
THE RESONANCE CHAMBER HAPPENS
BY USING YOUR MOUTH AS ONE.
UH...
SO, I JUST PUT IT IN
MY TEETH AND PLUCK IT.
(PLINKING QUIETLY)
WELL, IT'S MUCH LOUDER TO ME
BECAUSE I'M HEARING IT
THROUGH MY TEETH AND BONE
RIGHT INTO MY EARDRUM.
BUT IT PROBABLY DOESN'T
SOUND MUCH DIFFERENT FOR YOU.
SO, IN ORDER TO TAKE THE
NEXT STEP WITH THIS,
I'M GONNA THEN BREATHE OUT
WHILE I'M PLUCKING IT,
AND LET'S HEAR THE
DIFFERENCE THAT MAKES.
(BREATHING HEAVILY,
NOTE SOUNDING)
SO, SOMETIMES, THE SOUND NEEDS A
MEDIUM FOR IT TO BE CLEAR.
YOU CAN GET A SIMILAR
IDEA OF WHAT HAPPENED -
'CAUSE YOU PROBABLY DON'T
HAVE A JAW HARP AT HOME -
BUT JUST WITH A PEN OR PENCIL...
JUST IF YOU A PEN OR PENCIL,
JUST KIND OF SCRATCH IT OR...
KIND OF FLICK THE EDGE OF IT
THERE AND YOU WON'T HEAR MUCH.
BUT IF YOU PUT THIS
SO IT'S ON A TABLE
AND SIT YOUR EAR
RIGHT DOWN THE TABLE,
DO THE SAME THING AND LISTEN
FOR THE DIFFERENCE.
NOW THAT IT'S GOT THAT
MEDIUM TO TRAVEL THROUGH,
IT SHOULD SOUND A LOT
LOUDER AND FULLER
AND SIMPLY SCRATCHING THE PENCIL
CAN SOUND LIKE SOMEBODY...
SOMEBODY SAWING LOGS...
RIGHT NEAR YOU.
SO, YOU MAY WANT
TO THINK ABOUT THIS.
AND DO YOU HAVE ANY
NEW QUESTIONS?
YOU KNOW, PEOPLE HAVE BEEN
ASKING QUESTIONS ABOUT SOUND
FOR AN INCREDIBLY LONG TIME.
OVER 150 YEARS AGO,
IN THE MID-1800S,
A FRENCH INVENTOR -
EDOUARD-LÉON SCOTT -
WAS TRYING TO LOOK AT WHAT
SOUNDS LOOKED LIKE
AND HE WANTED TO KNOW HOW THEY
WERE DIFFERENT FROM ONE ANOTHER.
AND SO, HE MADE A DEVICE THAT,
WHEN IT HEARD SOME SOUND,
IT WOULD MOVE A TINY NEEDLE,
AND IF YOU MOVED PAPER UNDER IT
WHILE SOME NOISE WAS HAPPENING,
IT SORT OF WIGGLED AROUND
AND IT MADE SOMETHING
CALLED A PHONAUTOGRAM.
He shows a picture of transcribed sound waves.
He says AND SO...
EDOUARD SCOTT SANG THE SONG
"AU CLAIR DE LA LUNE."
AND WOUND UP CAPTURING
THE FIRST EVER AUDIO RECORDING.
EXCEPT, HE DIDN'T REALLY
KNOW IT AT THE TIME.
HE REALLY DIDN'T THINK
THERE WAS EVER GONNA BE A WAY
TO PLAY BACK SOUNDS.
HE WAS JUST HAPPY TO SEE
AND OBSERVE THAT THEY
COULD BE DIFFERENT.
SO, JUST TO GIVE YOU AN IDEA
'CAUSE THIS IS A COPY OF HIS... ..THAT THIS WOULD HAVE BEEN
ROLLED UP INTO A CYLINDER... ..AND THEN PLAYED
AND THEN TURNED OVER...
ROLLED UP INTO A CYLINDER
AND THEN TURNED OVER,
AS THE NEEDLE THEN MADE ALL THE
DIFFERENT IMPRESSIONS ON IT.
RIGHT THERE.
NOW, UH...
PAY ATTENTION IN
THE NEXT SEGMENT HERE,
WHEN YOU HEAR THE WORD "HERTZ."
HERTZ IS A FANCY AND PRECISE
WAY OF MEASURING PITCH.
IF YOU'VE EVER PLAYED
A MUSICAL INSTRUMENT
OR TAKEN ANY MUSIC LESSONS,
YOU'LL KNOW THAT NOTES
MAY HAVE DIFFERENT NAMES -
C, D, E, F, G,
B-FLAT.
AND YOU MAY EVEN THINK
OF THEM AS GOING UP OR DOWN
IN TONES OR SEMITONES.
BUT HERTZ IS A WAY
OF GOING FURTHER THAN THAT.
THINK OF IT A BIT
LIKE TEMPERATURE.
YOU MAY SAY
IT'S COLD OR CHILLY
OR HOT OR SCORCHING OUTSIDE.
BUT YOU CAN ALSO
GET A THERMOMETER AND KNOW,
"OKAY, IT'S 28 DEGREES."
OR 15 DEGREES.
HERTZ WORKS THE SAME WAY,
EXCEPT RATHER THAN SAY
SOUND IS HIGH OR LOW,
WE CAN GIVE IT A
VERY PRECISE NUMBER,
AND THIS IS SOMETHING YOU'LL
WANT TO TAKE INTO CONSIDERATION
WITH THE LOUDEST SOUND.
AND THIS NEXT SEGMENT,
ONE QUESTION I HAVE
GOING INTO IT IS
"WHAT WOULD EDOUARD-LÉON SCOTT
"THINK OF WHAT IS
ABOUT TO HAPPEN."
Back to Science Max, Phil says MIKAELA AND I HAVE TRIED
A RESONANCE CHAMBER
AND A GIANT MEGAPHONE
TO MAKE SOUND LOUDER.
NOW, IT'S TIME TO MOVE ON TO
THE NEXT STEP OF THE PLAN -
USING ELECTRICITY TO HELP US
AMPLIFY SOUND
AND THAT MEANS SPEAKERS.
SO, SPEAKERS
THAT YOU HAVE AT HOME.
THREE DIFFERENT
SPEAKERS HERE, RIGHT?
THREE DIFFERENT CONES.
Mikaela says YEAH, THERE'S
A LOT GOING ON HERE.
Phil says SO, WHAT'S THE DEAL?
Mikaela says WELL, HERE AT THE BOTTOM,
WE HAVE A SUBWOOFER.
Phil says A SUB-- WAIT A MINUTE,
A SUBWOOFER?
Mikaela says SUBWOOFER.
Phil says SO, IT'S A WOOFER?
THE WORD IS "WOOFER"?
Mikaela says YEP!
Phil says OKAY, SO IT'S FOR DOGS. RIGHT?
Mikaela says NO! NO! A SUBWOOFER IS FOR LOW
NOTES HERE IN OUR SPEAKER.
Phil says AH!
Mikaela says AT THE TOP HERE,
WE HAVE A TWEETER.
Phil says SO, IT'S FOR BIRDS!
IT'S BIRDS, DOGS.
SO, LET ME GUESS.
LOW NOTES?
Mikaela says YEAH.
Phil says TWEETER IS HIGH NOTES?
Mikaela says YEAH! HIGH NOTES!
Phil says YEAH.
Mikaela says AND THEN WE HAVE THIS
GUY HERE IN THE MIDDLE
AND THAT'S CALLED
YOUR MID-RANGE SPEAKER.
Phil says OH, THAT'S NOT NEARLY
AS COOL A NAME.
NOW, WE HAVE SPEAKERS.
WE'VE TAKEN A LOOK OF THAT.
BUT WHY DON'T WE
TAKE ONE APART? RIGHT?
Mikaela says COOL!
YEAH! LET'S DO IT.
Phil says I'VE GOT THIS ONE HERE
THAT I SPILLED JUICE ON.
SO, IT DOESN'T WORK ANYMORE,
SO I'VE KIND OF TAKEN IT APART,
Mikaela says COOL!
Phil says SO, IT'S GOT...
Mikaela says OH, MAN,
THAT'S AWESOME.
Phil says OKAY, SO IT'S GOT
THE COVER.
THAT'S COOL.
SO, WHAT I FIND INTERESTING
IS THERE'S THE SPEAKER
AND THE WIRES, RIGHT?
BECAUSE IT'S ELECTRICAL
AMPLIFICATION,
BUT CHECK THIS OUT.
THIS IS JUST A RING
TO HOLD THAT ON
AND THE REST IS
JUST AN EMPTY BOX
WE KNOW WHAT THAT IS.
They both say RESONANCE CHAMBER!
Phil says THAT'S RIGHT,
SO THAT'S WHY IT'S AN EMPTY BOX.
Mikaela says LET'S TAKE THIS APART, TOO,
SEE WHAT'S GOING ON.
Phil says SO, THAT'S JUST...
THAT'S THE PAPER CONE, RIGHT?
SO, THAT'S THE...
LIKE, THAT'S THE DRUM, I GUESS.
IT'S LIKE EARDRUM,
THE THING THAT VIBRATES.
Mikaela says YES. YEAH.
THIS WHOLE THING VIBRATES.
THAT'S OUR ELECTROMAGNET.
WHEN WE TURN THIS ON, THE
ELECTROMAGNET GOES ON AND OFF
AND IT'S CAUSING
THIS WHOLE THING TO VIBRATE.
Phil says SO, THAT'S HOW IT WORKS.
IT'S THE ELECTRICITY TURNING
THE ELECTROMAGNET ON AND OFF
Mikaela says EXACTLY.
Phil says AND IT'S ON AND OFF,
ON AND OFF, ON AND OFF,
ON AND OFF, ON AND OFF,
AND IT MAKES IT VIBRATE
AT CERTAIN SPEEDS, RIGHT?
Mikaela says YEP.
Phil says HERTZ.
THE NUMBER OF TIMES IT
VIBRATES PER SECOND IS HERTZ.
WHAT WE COULD DO IS WE COULD
MAX IT OUT WITH THE SPEAKER
AND PLUG THE PHONE
IN THE SPEAKER,
BUT THIS STEP DOES NOT FEEL LIKE
SCIENCE MAX
TO ME,
BECAUSE ANYBODY
CAN DO THAT, RIGHT?
Mikaela says YEAH.
Phil says YOU CAN JUST TURN UP
YOUR TELEVISION RIGHT NOW
AND THAT'S PRETTY MUCH
THE SAME KIND OF THING.
WE NEED ELECTRICAL
AMPLIFICATION, BUT MAX IT OUT.
Mikaela says MAX IT OUT.
WHAT ARE YOU THINKING?
Phil says OKAY, SO I'VE GOT A FRIEND
AND HE'S GOT A STEREO
SYSTEM THAT HE BUILT,
HE PUT TOGETHER,
AND WHAT HE DOES IS HE
TOURS DIFFERENT CITIES.
SO, HE SAID HE'D BRING IT BY
SCIENCE MAX HEADQUARTERS.
Mikaela says WHAT?!
HE'S GONNA BRING IT HERE?!
Phil says WE'VE GOT TO GO OUTSIDE.
Mikaela says I CAN'T WAIT TO SEE THIS THING.
Phil says AND IT'S VERY LOUD,
SO WE HAVE TO GO OUTSIDE.
Mikaela says WHEN IS HE COMING?
Phil says UM... RIGHT NOW.
ALL RIGHT.
LET'S GO CHECK IT OUT.
The caption changes to "Max Fax!"
Phil says SEEING SOUND VIBRATIONS IS FUN.
THIS KIND OF SPEAKER
IS A SPECIAL KIND.
IT'S CALLED A SUBWOOFER,
WHICH IS DESIGNED TO
GIVE YOU THE LOW NOTES,
THE BIG RUMBLY BASE SOUNDS.
I TILT THE SPEAKERS
SO IT'S FACING UP
AND COVER IT WITH
BIG SHEETS OF PLASTIC WRAP,
WHICH I PUSH INTO THE CONE,
THEN TAPE IT
SO IT'S NICE AND SECURE.
THEN WHAT YOU NEED IS
SOME CORN STARCH MUD,
WHICH IS TWO PARTS CORN STARCH,
ONE PART WATER.
I'VE GOT SOME YELLOW CORN STARCH
AND SOME BLUE CORN STARCH.
THIS EXPERIMENT WORKS
THE BEST WITH LOW NOTES.
I'M PLAYING A TONE THROUGH THE
STEREO THAT IS VERY LOW.
HERE'S WHAT HAPPENS
WHEN I TURN UP THE VOLUME.
(LOW RUMBLING)
(LOW RUMBLING)
The corn starch mud starts jumping.
Phil says WHOA!
(LAUGHING)
(LOW RUMBLING)
IT'S ALIVE!
(LOW RUMBLING)
YOU SEE, CORN STARCH MUD
IS A SHEER THICKENING FLUID,
WHICH MEANS WHEN YOU IMPACT IT,
IT TURNS SOLID.
SO, THE VIBRATIONS
FROM THE SPEAKER CONE
ARE MAKING THE
CORN STARCH MUD IMPACT
AND THAT'S TURNING INTO A SOLID,
BUT THEN IT SORT OF ALSO
MELTS BACK INTO A LIQUID,
SO YOU GET LITTLE
COLUMNS OF CORN STARCH
COMING UP AND
FALLING DOWN AGAIN.
IT'S LIKE IT'S DANCING.
WHOA!
(LOW RUMBLING)
VISUAL SOUNDWAVES!
SCIENCE!
SO, MIKAELA AND I
ARE GOING TO MAX OUT SOUND.
TO DO THAT, WE NEED
A MAXED OUT SOUND SYSTEM!
They walk out to the parking lot.
Phil says THIS IS GOING TO BE AMAZING.
Mikaela says IT'S SO COOL!
Phil says THIS IS GONNA BE SUPER
MAXED SOUND EXPERIMENT.
THIS IS JAMES, MIKAELA.
Mikaela says HEY, JAMES! HOW ARE YOU?
James says NICE TO MEET YOU.
Phil says THANKS FOR COMING, BUDDY.
James is in his thirties, with his head shaven and wears jeans, a black T-shirt and a yellow lab coat.
James says NICE TO BE HERE.
Phil says SO, TELL US ABOUT
YOUR SPEAKER SYSTEM!
IT LOOKS A LOT LIKE A VEHICLE.
James says THIS IS MY AUDIO VAN.
IT'S GOT FOUR 15-INCH
SUBWOOFERS IN THE BACK,
IT'S GOT A WHOLE BUNCH
OF POWER TO POWER IT,
AND I'M GLAD TO BE HERE
TO LET YOU GUYS HEAR IT TODAY.
Phil says AWESOME!
SO, IF I HAVE A SPEAKER AT HOME,
LIKE A LITTLE SPEAKER LIKE THIS,
HOW MANY WATTS DO
YOU THINK THAT WOULD BE?
James says SOMEWHERE BETWEEN 15 AND 25.
Phil says 15 AND 25 WATTS.
James says YES.
Phil says AND YOU'VE GOT 4,000?
James says YES.
Phil says SO, THAT'S A LOT MORE.
YEAH, IT'S QUITE A BIT.
Phil says AND SUBWOOFER?
THEY PLAY LOW NOTES?
James says YES.
Phil says SO, IS THAT BETTER WHEN
YOU HAVE A VAN LIKE THIS?
James says WITH A CAR AUDIO VAN LIKE THIS,
YOU WANT TO PLAY LOW NOTES.
LIKE YOUR HOUSE STEREOS
AND THAT WILL PLAY ANYTHING
FROM 120 TO 200 HERTZ.
I'M PLAYING 20 HERTZ
TO ABOUT 35 MAX
FOR YOU GUYS TODAY.
Phil says SO, THAT'S LIKE A SORT OF
RUMBLE OF THUNDER AND...
James says YES, VERY LOW.
(MAKING SHAKING SOUND)...
A caption reads "Listen closely, can you hear it?"
Phil says WHERE YOU REALLY FEEL IT.
IT'S LIKE A TRAIN
GOING PAST ALMOST.
James says YES.
Mikaela says OH, THAT'S COOL.
Phil says SO, WE GET OUR HEARING
PROTECTION ON
AND WE TRY IT OUT.
I KNOW WHAT YOU'RE THINKING.
PHIL, WHAT'S THE POINT
OF HAVING LOUD MUSIC
IF YOU CAN'T REALLY HEAR IT?
BECAUSE WE'VE GONE FROM
LISTENING TO MUSIC
TO FEELING IT.
They put on earmuffs.
(RUMBLING)
(LAUGHING)
Phil says THE SOUNDWAVES ARE SO STRONG
THAT THEY HAVE BECOME
A PHYSICAL PRESENCE.
MIKAELA'S HAIR FLIES AROUND,
BECAUSE THE AIR
FROM THE SPEAKERS
IS CREATING SHOCKWAVES.
THE SOUNDWAVES ARE SO POWERFUL,
THEY MOVE THE
AIR BACK AND FORTH
WHICH MAKES MIKAELA'S HAIR
DANCE ALL OVER THE PLACE,
AND MY HAIR NOT SO MUCH.
(SCREAMING)
(LAUGHING)
(LOW RUMBLING)
(WHOOPING)
(LOW RUMBLING)
Phil says SCIENCE!
(RUMBLING)
(LOW RUMBLING)
Phil says I'M TOTALLY JEALOUS
OF YOUR LONG HAIR.
Mikaela says YEAH, YOU NEED
TO GET LONGER HAIR.
Phil says OKAY, HOLD ON.
He puts on a wig and says OKAY.
WHOA!
SCIENCE MAX:
EXPERIMENTS AT LARGE!
They both say SUPER SOUND!
Phil says HIGH FIVES!
OKAY, READY TO DO AGAIN?
SO COOL!
Mikaela says YEAH! LET'S DO IT.
Phil says OKAY! THERE WE GO!
(LOW RUMBLING)
(RUMBLING)
They say AHH!
(LOW RUMBLING)
WHOO!
Now the end credits roll as gag reels from the show play.
Mikaela says IS IT AT THE BOTTOM?
Phil says I CAN'T...
I CAN'T REACH IT.
SO, THAT'S GREAT.
(SCREAMING)
The giant megaphone rolls off the table.
Phil says WAIT, WAIT...
ALMOST...
Phil drops his phone in a hole and says NO, I CAN'T.
At the parking lot, Phil says OKAY! I'VE GOT THE
HEARING PROTECTION ON!
Mikaela says PARDON?
Phil says YOU GOT YOUR
HEARING PROTECTION ON?
Phil says WHAT WAS THAT?
(CHUCKLING)
Phil rescues his phone and chuckles.
Mikaela says YAY!
Phil says HELLO?
OH, HI, MOM.
NO, I'M SHOOTING THE SHOW
Teacher James says RIGHT NOW. I CAN'T...
SCIENCE.
NOW, I CANNOT HELP BUT WONDER
HOW LOUD IT WAS IN THAT VAN.
DURING THE EPISODE
WE JUST WATCHED,
WE'VE SEEN SOUND VISUALIZED
IN A NUMBER OF DIFFERENT WAYS.
THERE'S BEEN THE DRUM WITH SALT
AND OTHER PARTICLES ON IT.
THERE'S BEEN THE
CORN STARCH MUD.
AND THEN, WE SAW THAT
LOUD ENOUGH SPEAKERS
AND LOW ENOUGH TONES WILL...
MOVE PEOPLE'S HAIR LIKE WIND.
WE ALSO HAD A LOOK AT
THE PHONAUTOGRAMS.
NOW, IF YOU THINK BACK TO THE
LIST THAT WE SAW...
THAT WE PUT TOGETHER
IN THE BEGINNING,
MAYBE YOU CAN SEE
THAT THERE'S ANOTHER WAY
THAT WE CAN VISUALIZE SOUND.
NOW, FOR THIS NEXT PART,
MAKE SURE THAT YOU
HAVE THE PERMISSION
OF THE BIG PEOPLE YOU LIVE
WITH BEFORE YOU START
AND DO BE CAREFUL ABOUT
DOING ANY OF THIS
BECAUSE WE'RE GOING TO ASK YOU
TO CUT SOME CANS AND ALL.
IF YOU CAN GET A RECYCLED CAN
AND THEN TAKE BOTH ENDS OFF
OF IT-- AGAIN, BE CAREFUL.
SOME OF THIS IS SHARP.
YOU MAY EVEN WANT TO PUT SOME
TAPE OVER ONE OF THESE ENDS.
AND THEN, FIND A BALLOON,
AND CUT THE END OFF OF IT
WHERE YOU WOULD NORMALLY
BLOW AIR INTO IT.
AGAIN, BE CAREFUL.
AND THEN, STRETCH IT OVER,
SO MAKE KIND OF
ANOTHER TINY DRUM.
AND I HAPPEN TO HAVE
A SMALL MIRROR
THAT I THEN ATTACHED
TO THIS TAPE.
YOU COULD ALSO USE A DIME,
IF YOU'VE GOT, LIKE,
A SHINY STICKER THAT,
YOU KNOW, LOOKS REALLY CLEAR,
A NUMBER OF THINGS MIGHT WORK.
THEY MAY OR MAY NOT BE AS CLEAR.
AND IF YOU'VE GOT A CAT AROUND,
MAYBE YOU'VE GOT ONE
OF THESE LASER POINTERS THERE.
AND JUST MAKE SURE YOU BE
CAREFUL WITH THIS,
WE DON'T SHINE IT AROUND
ANYONE'S EYES AND THAT
'CAUSE IT CAN DAMAGE YOUR...
DAMAGE YOUR VISION.
SO, IN A MOMENT,
I'M GONNA SET THIS UP
AND I'M GONNA USE SOME TRIPODS
AND OTHER THINGS TO
KEEP IT VERY STILL,
SO YOU CAN SEE THAT THE MOVEMENT
WILL BE COMING FROM THE SOUND
AND NOT JUST ME HOLDING AND...
AND THIS BEING SHOOK AROUND.
IF WE PUT...
IF I SHINE THAT ON...
YOU CAN SEE THERE'S THE
REFLECTION BEHIND ME.
As he points the laser against the mirror, it reflects on the wall behind James.
He says IF WE START PUTTING SOME SOUNDS
THROUGH THE OPEN
END OF THIS CAN,
WHAT'S GONNA HAPPEN ON THE IN...
WHAT IS GONNA HAPPEN TO THE
REFLECTED DOT OVER THERE?
REMEMBER BACK TO
THE WAY THE CRYSTALS,
THEY WOULD JUMP AROUND WHEN IT
HEARD THE SOUND THERE.
WHAT IS THAT GONNA
DO TO THE MIRROR
AND WHAT WILL SEE THAT...
WHAT WILL WE SEE THAT DO?
OKAY.
TRY TO THINK AND PREDICT TO
YOURSELF WHAT YOU'RE GONNA SEE
AND THEN WE'RE GOING TO...
WE'RE GOING TO SHOW YOU EXACTLY
WHAT'S GOING TO HAPPEN THERE.
NOW, MAYBE I CAN GET A NICE
'80S VIDEO TOASTER TRANSITION
INTO THIS NEXT PART.
SO, I'VE, UH...
RIGHT HERE, I'VE GOT THE
LASER POINTER ON A TRIPOD.
IT'S GOING INTO THE MIRROR
AND WE CAN SEE
ITS REFLECTION HERE.
NOW, I'M GONNA PLAY...
JUST SOME RHYTHMS HERE
AND LET'S WATCH WHAT HAPPENS
TO OUR LASER POINT.
(DRUM BEAT PLAYING)
The reflection starts moving around and changing shapes.
(DRUM BEAT PLAYING)
James says YEAH, SO, IT'S MOVING AROUND.
AS THE MIRROR MOVES
ON TOP OF THE BALLOON,
THE BALLOON IS SHOOK BY
THE SOUNDWAVES THERE,
AND WE CAN SEE, YOU KNOW,
SOME OF THE DIFFERENT BEATS
HAPPENING RIGHT IN FRONT OF US.
LET'S-- LET'S DO ANOTHER ONE.
(ROCK BEAT PLAYING)
(ROCK BEAT PLAYING)
James says SO, YOU MAY WANT TO WRITE
DOWN A QUESTION OR TWO NOW.
YOU ALSO MAY WANT TO CONNECT.
WHEN HAVE YOU SEEN A
PRESENTATION LIKE THIS,
WHERE THERE'S SOUND AND
THERE'S SOME KIND OF LASERS?
DOES IT WORK
SOMETHING LIKE THIS?
HERE'S SOMETHING
INTERESTING, THOUGH.
WE SEE A WHOLE LOT OF
DIFFERENT SQUIGGLES AND SOUNDS
BECAUSE WHEN YOU HEAR EVEN
JUST A DRUM BEAT LIKE THAT,
THERE'S THINGS HAPPENING ON
ALL KINDS OF FREQUENCIES -
THERE'S THE
HIGH-PITCHED CYMBALS,
THERE'S THOSE KIND OF
MEDIUM-PITCHED
SNARE DRUMS AND TOMS,
AND THEN YOU HAVE
THOSE LOW BASS DRUMS
THAT YOU JUST KIND OF FEEL MORE
THAN YOU ACTUALLY HEAR.
BUT WE CAN ALSO PLAY...
JUST-- JUST PLAY
A STRAIGHT TONE.
LET'S HEAR WHAT HAPPENS
WHEN I PUT IN JUST A...
JUST 200-- 200 HERTZ.
LET'S HEAR.
(MEDIUM TONE BLARING)
The reflection makes a circle.
(MEDIUM TONE BLARING)
James says DID YOU SEE THAT?
SO, WHEN WE WERE PLAYING
JUST THAT STRAIGHT TONE,
IT MADE JUST A CIRCLE.
AND THEN, WHEN SOME OTHER
INTERFERENCE CAME IN,
IT MADE KIND OF A FIGURE-EIGHT.
LET'S GO A LITTLE LOWER.
LET'S GO TO 150 HERTZ.
(LOW TONE BLARING)
(LOW TONE BLARING)
(LOW TONE BLARING)
(BEAT PLAYING)
SO, YEAH, ONCE AGAIN,
WE SAW THE SAME THING.
WHEN IT'S-- WHEN WE HAVE
THAT ONE CLEAN FREQUENCY,
IT MAKES THE...
IT MAKES OUR DEVICE
RESONATE IN SUCH A WAY
THAT IT BECOMES A LITTLE BIT
MORE-- MORE EVEN ALL OVER IT
AND WE START GETTING
THESE MORE PRECISE,
MORE MATHEMATICAL PATTERNS.
LET'S TRY-- LET'S GO DOWN
ONCE MORE TO 50 HERTZ
AND SEE WHAT WE CAN GET.
(LOW TONE BLARING)
The reflection stretches and makes circles.
(LOW TONE BLARING)
(LOW TONE BLARING)
James says YEAH. INTERESTING.
SO, IF YOU CAN MAKE A DEVICE,
SOMETHING LIKE THIS,
IF THE ADULTS IN YOUR HOUSE ARE
OKAY WITH YOU DOING THAT,
WHAT DO YOU THINK
SOME SONGS THAT YOU LIKE
ARE GOING TO LOOK LIKE?
NOW...
WE WERE TALKING ABOUT
USING HERTZ TO DESCRIBE
SPECIFIC MEASUREMENTS
WITH SOUND,
BUT THIS ALSO BECOMES USEFUL
WHEN THINKING ABOUT THINGS
THAT-- THINGS THAT WE CAN HEAR.
SO, AS HUMAN BEINGS,
WE CAN HEAR ABOUT...
UPWARDS TO 20 KILOHERTZ.
WE CAN HEAR THINGS UP
TO 20 HERTZ
AND AS HIGH AS 20 KILOHERTZ.
AND KILOHERTZ IS A FANCY WAY OF
SAYING 20,000 HERTZ.
THINK OF THIS LIKE KILOMETRES.
WE HAVE...
WHEREAS...
1000 METRES IS THE
SAME AS A KILOMETRE,
1000 HERTZ IS THE SAME
AS A KILOHERTZ.
SO, WHEN WE START TALKING
LARGER NUMBERS OF HERTZ,
IT JUST BECOMES
EASIER TO SAY THAT.
SO, HUMANS CAN HEAR UPWARDS OF...
UPWARDS OF 20,000, BUT THAT'S
NOT THE SAME FOR EVERYONE
BECAUSE MOST PEOPLE,
AS THEY GET OLDER,
THEY TEND TO LOSE A BIT OF
THAT HIGH END HEARING.
YOU CAN PROBABLY HEAR
SOUNDS AROUND 17, 18,
19, OR 20 KILOHERTZ THAT THE
ADULTS AROUND YOU CAN'T.
AND-- WELL, AND THEN
THERE'S SOME ANIMALS, LIKE...
OH, LIKE ZOEY HERE.
ZOEY. COME HERE, ZOEY.
He hugs his little black dog and says SO, ZOEY CAN HEAR SOUNDS
UP TO 45 KILOHERTZ.
SO, IF YOU'VE GOT,
LIKE, A DOG OR CAT
THAT MIGHT SEEM TO ACT LIKE
THEY'RE HEARING THINGS
WHEN YOU CAN'T HEAR ANYTHING,
IT MIGHT BE THAT THEY'RE
ACTUALLY LISTENING TO SOMETHING
OR HEARING SOME NOISE FAR OFF.
OKAY. DO YOU HAVE ANY QUESTIONS?
THIS'D BE A GOOD TIME
TO WRITE THEM DOWN.
(CHIME SOUNDING)
NOW, ON THE OTHER HAND,
WE SAW THAT, IN
SCIENCE MAX,
THAT LOWER FREQUENCIES,
LOWER HERTZ SOUNDS
ARE MORE FELT THAN LISTENED TO.
AND THINK ABOUT SOME
MUSIC YOU'VE HEARD.
WHAT ARE THE INSTRUMENTS YOU
HEAR THAT ARE LOW
AND THAT YOU FEEL
MORE THAN YOU HEAR?
PEOPLE WHO GET INVOLVED
WITH MUSIC PRODUCTION
AND MAKING MUSIC HAVE
TO BE AWARE OF THIS
AND THERE'S ALL
KINDS OF JOBS IN SOUND.
YOU MAY BE INTERESTING IN
SEEING MORE OF THE CAREERS
THAT YOU CAN TAKE PART IN
SOUND ENGINEERING
WITH THIS EPISODE OF
WHEN I GROW UP
AND A LOOK AT SOUND ENGINEERS.
OKAY, READY, ZOEY?
Mikaela pops up against a colourful animated background. She's around 13, with mid-length curly brown hair, and wears a blue sweater.
[WHOOSH]
She says MY NAME'S MIKAELA, AND SINCE
I CAN REMEMBER,
I'VE DREAMT ABOUT WHAT I'LL BE
WHEN I GROW UP!
THERE ARE SO MANY COOL JOBS,
SO I DECIDED TO TRY THEM ALL.
In animation, gear from different jobs appears on her: an astronaut's helmet, a construction worker's vest and helmet, a chef's hat and apron, and a police officer's hat and badge.
She says I BUILT AN AWESOME STUDIO IN
MY GARAGE,
SO I CAN MAKE AND SHARE VIDEOS
ABOUT MY JOURNEY.
She pops up in her garage. The place has a multi-coloured tile floor, hangers with different uniforms, a bike, a desk, and a colourful back wall with a graffiti that reads "When I grow up!"
She says IT'S ALL ABOUT DISCOVERING
WHAT I'LL BE
WHEN I GROW UP!
The name of the show appears in purple surrounded by colourful silhouettes of different animals and shapes. It reads "When I grow up."
A film countdown clocks appears.
In her studio, Mikaela says OH, HEY, EVERYONE.
I'M HARD AT WORK
EDITING A NEW VIDEO.
RIGHT NOW,
I'M FOCUSING ON THE SOUNDS.
THAT'S RIGHT - SOUND.
DID YOU KNOW THAT'S
A HUGE PART OF EDITING?
FOR EXAMPLE,
WHAT IF THE SOUND DOESN'T
MATCH UP WITH THE PICTURE?
DOESN'T MATCH UP
WITH THE PICTURE!
DOESN'T MATCH UP
WITH THE PICTURE!
OR A SOUND EFFECT THAT,
WELL, DOESN'T SOUND RIGHT.
As he drops a pen, a glass breaking sound is heard.
As he rings a bell, a dog barking sound is heard.
(GLASS BREAKING)
(BOING SOUND)
(DOG BARKING)
Mikaela says THERE'S A JOB THAT FOCUSES
COMPLETELY ON EDITING SOUND.
IT'S CALLED A SOUND EDITOR.
I'M GONNA CHECK OUT THE JOB,
SO MY AUDIO DOESN'T
SOUND LIKE THIS...
(ROOSTER CROWING)...WHEN I GROW UP.
Now in a different building, Mikaela says THIS IS WHERE SOUND EDITORS
WORK ON TV AND MOVIES
TO MAKE EVERYTHING
SOUND AWESOME!
IT'S SO COOL BECAUSE THERE'S
SO MANY COMPUTERS...
(VOICE ECHOING:)...AND VIDEOS, AND-- WAIT.
(NORMAL AUDIO:)
CAN YOU GUYS HEAR ME?
I THINK I KNOW WHAT HAPPENED.
GOOD THING WE'RE AT THE RIGHT
PLACE TO SEE HOW IT'S DONE.
COME ON!
As she walks inside, she says WOW! THIS PLACE IS MUCH
BIGGER THAN MY STUDIO.
Claire says HEY, MIKAELA.
Mikaela says OH, HI, CLAIRE.
CLAIRE'S A SOUND EDITOR HERE.
CLAIRE, WHAT'S YOUR FAVOURITE
PART ABOUT BEING A SOUND EDITOR?
Claire is in her thirties, with long straight red hair and wears jeans and a black sweater.
She says MY FAVOURITE IS HAVING FUN
AND MAKING IT WORK.
Mikaela says COOL. LET'S GO.
BUT FIRST, SHOULD OUR
FOOTSTEPS BE NORMAL OR SILLY?
UMM...
Claire says SILLY.
Mikaela says AGREED.
(HORN HONKING)
Mikaela says ONE, TWO, ONE...
(HORN HONKING)
Claire says OKAY, MIKAELA,
IF WE'RE GONNA DO SOME SOUND
EDITING, WE'RE NEED A VIDEO.
DID YOU BRING ONE?
Mikaela says YEP. I FILMED ONE SPECIAL
JUST FOR TODAY.
LET'S WATCH IT!
Mikaela says I CAN'T WAIT.
(BREATHING IN AND OUT)
In the video, Mikaela takes a walk outside.
A skater almost bumps into her and says WHOA! SORRY, DUDE!
OOPS.
She crawls through a crawl tube and shrugs.
The video ends.
Mikaela says STUNNING, JUST STUNNING!
WHAT DID YOU THINK, CLAIRE?
Claire says I THINK IT'S A GREAT VIDEO
TO HAVE SOME FUN
WITH SOUND EDITING.
WE CAN DO SOME SOUND EFFECTS.
WE CAN DO FOLEY
FOR THE HOPSCOTCH.
WE CAN WORK ON THE DIALOGUE
FOR THE SKATEBOARDER.
AND THEN,
WHEN YOU GO INTO THE TUBE,
WE CAN HAVE A LOT OF FUN.
Mikaela says SOUNDS GOOD!
(WACKY CARTOON
SOUND EFFECTS SOUNDING)
(MUFFLED MUSIC PLAYING)
Back in her studio, Mikaela says OH, HI, THERE.
SPEAKING OF SOUND,
I WAS JUST
TESTING OUT SOME MUSIC
I'M GONNA USE IN
ONE OF MY VIDEOS.
ANYWAY, WHY DON'T YOU CHECK OUT
HOW CLAIRE BECAME
A SOUND EDITOR.
(MUFFLED MUSIC PLAYING)
In animation, a comic book cover appears with the title "When they were growing up! By Mikaela!"
[PAGE FLIP]
The pages of a comic book flip.
A frame shows a little girl playing the piano.
Mikaela says WHEN CLAIRE WAS A KID,
SHE LOVED PLAYING MUSIC,
SO SOUND WAS VERY
IMPORTANT TO HER.
IN HIGH SCHOOL,
SHE STARTED MAKING SHORT FILMS
ABOUT HER EVERYDAY LIFE.
Another frame shows little Claire filming a butterfly.
Mikaela says CLAIRE LOVED WORKING
ON THE SOUNDS
THAT WENT INTO THE FILMS.
SHE WAS AMAZED
AT HOW MUCH A SCENE
COULD CHANGE JUST WITH SOUND!
(HORSE HOOVES POUNDING)
Another frame shows Claire watching a western movie.
Mikaela says AT FILM SCHOOL,
CLAIRE LEARNED THAT
THERE WAS A PART OF FILMMAKING
FOCUSED COMPLETELY ON SOUND.
Claire says WOO-HOO!
SHE ENJOYED IT SO MUCH,
FROM THAT POINT ON,
SHE KNEW SHE WANTED
TO BE A SOUND EDITOR.
(TRUMPET SOUNDING)
Mikaela says NOW THAT YOU'VE
LEARNED ABOUT CLAIRE
LET'S GET BACK TO THE SHOW
(RIM SHOT SOUNDING)
DING
Claire says ALL RIGHT, MIKAELA,
WELL, THIS IS WHERE WE'RE
GOING TO BE RECORDING FOLEY
AND ANDREA'S GONNA
RECORD IT FOR US.
Mikaela says HI, ANDREA!
Andrea says HI, MIKAELA.
Andrea is in her thirties, with long straight brown hair and wears a gray cardigan sweater and a black scarf.
Claire says NOW, THE AUDIO FROM WHEN
YOU WERE PLAYING HOPSCOTCH
DIDN'T QUITE WORK,
SO WE'RE GONNA RECREATE IT
HERE IN THE STUDIO.
Mikaela says AWESOME!
Claire says YOU GOT IT, THAT'S YOUR
HOPSCOTCH COURSE.
NOW, ANDREA'S
GONNA ROLL THE VIDEO
AND YOU'RE GOING TO DO YOUR
STEPS IN REAL TIME HERE
AND MATCH WHAT
YOU SEE IN THE VIDEO.
Mikaela says GOT IT.
Claire says I'M GONNA GET OUT OF YOUR WAY.
Mikaela says ROLL IT, ANDREA!
(THUDDING)
As she sees herself in the video playing hopscotch, she stomps her feet on the platform.
(THUDDING)
She says WHOO!
Claire says THAT WAS PRETTY GOOD!
I THINK WE GOT IT.
Mikaela says WAIT. CAN I JUST DO ONE MORE?
Claire says SURE.
Mikaela says ROLL IT AGAIN, ANDREA!
(THUDDING)
(THUDDING)
(THUDDING)
Mikaela says DID WE GET THAT ONE, ANDREA?
Andrea gives her the thumbs up.
Mikaela says NICE.
NOW THAT WE'VE DONE FOLEY,
CLAIRE'S GONNA SHOW ME
HOW TO DO SOUND EFFECTS
TO MAKE A VIDEO SEEM MORE FUN.
HOPEFULLY, IT'S A SNAP!
She snaps her fingers.
(SQUEAKY DOOR OPENING SOUND)
Mikaela says I MEAN, A SNAP.
(SNEEZING SOUND EFFECT)
I MEAN, A SNAP.
(SPLASHING)
I MEAN, A SNAP!
(MEOWING)
I MEAN, A SNAP!
(SNAPPING SOUND)
(SIGHING)
Claire says OKAY, MIKAELA,
SO THIS IS MY OFFICE.
Mikaela says COOL.
Claire says AND THIS IS WHERE
I DO MY SOUND EDITING.
WHAT SOUND EFFECTS
ARE WE DOING FIRST?
Claire says WELL, THE FIRST SCENE IN YOUR
VIDEO TAKES PLACE IN THE PARK,
WHERE YOU'RE JUST WALKING ALONG.
SO, WE WANT TO THINK
ABOUT ALL THE SOUNDS
THAT YOU COULD BE
HEARING IN THE BACKGROUND.
(SHEEP BLEATING)
(ANIMAL NOISES BLARING AT ONCE)
An animated Mikaela in the park says PHEW!
Mikaela says WHAT DID YOU HAVE IN MIND?
Claire says WELL, YOU COULD HEAR SOME BIRDS.
(BIRDS CHIRPING)
(BIRD CHIRPING)
Claire says WE COULD HEAR SOME TRAFFIC.
(ENGINES RUMBLING)
Claire says YOU COULD HEAR A POLICE SIREN.
(SIREN BLARING)
(SIREN BLARING)
Claire says AND IN A PARK, YOU COULD EVEN
HEAR PEOPLE PLAYING TENNIS,
LIKE THIS.
(WHACKING SOUNDS)
(WHACKING SOUNDS)
Mikaela says WHAT ABOUT THE SKATEBOARDER?
Claire says WELL, YOU COULD HAVE THE NATURAL
SOUND OF A SKATEBOARD GOING BY.
(SKATEBOARD RATTLING)
Claire says OR YOU COULD DO SOMETHING
A LITTLE DIFFERENT.
(SLIDE WHISTLE TRILLING)
Mikaela says THAT'S THE ONE.
AND WHAT ABOUT WHEN
I WENT THROUGH THE TUBE?
I WAS THINKING
SOMETHING... CRAZY!
Claire says OH.
WELL, HOW ABOUT THIS?
(CREAKING,
VOICE CACKLING)
(GIGGLING)
(CAT YOWLING)
Mikaela says THAT'S DEFINITELY CRAZY.
GUYS, THIS IS SO COOL.
CLAIRE'S ABOUT TO
SHOW ME HOW TO RECORD ADR.
THAT STANDS FOR
AUTOMATED DIALOGUE REPLACEMENT.
IT MEANS THAT YOU CAN RECORD
YOUR VOICE TO REPLACE AUDIO
THAT DIDN'T WORK OR MAKE
YOUR VOICE SOUND DIFFERENT.
In a high-pitch voice, she says LIKE THIS.
In a low-pitch voice, she says OR LIKE THIS.
In a scary, low-pitch voice, she says OR LIKE THIS.
Back in Claire's office, Mikaela says HOW DOES THIS WORK, CLAIRE?
Claire says SO, IN VIDEOS, IT'S REALLY
IMPORTANT TO UNDERSTAND
WHAT PEOPLE ARE SAYING.
SO, I THINK THERE
ARE A FEW PLACES
WHERE IT WOULD BE A GOOD IDEA
TO REPLACE IT WITH ADR.
WHEN YOU FIRST WALK IN,
YOU TAKE A BIG BREATH.
AND THEN, LATER, WHEN THE
SKATEBOARDER ROLLS BY,
THE SKATEBOARD WAS REALLY LOUD,
SO WE COULDN'T REALLY
HEAR WHAT HE SAID.
DO YOU WANNA REDO HIS VOICE?
Mikaela says TOTALLY, DUDE.
Claire says AND THEN,
WHEN YOU GO IN THE TUBE,
YOU CAN DO WHATEVER YOU WANT.
HERE'S YOU MICROPHONE,
SO WHENEVER
YOU'RE READY TO ROLL.
She puts on her headphones and says AND ACTION!
(BREATHING IN AND OUT)
In the skater's voice, she says WHOA! SORRY, DUDE!
Claire says THAT WAS PRETTY GOOD, BUT LET'S
TRY IT A LITTLE BUT FASTER.
Mikaela says OKAY.
WHOA! SORRY, DUDE!
WHAT'D YA THINK?
Claire says THAT WAS EXCELLENT.
As she sees herself crawl inside the tube, she says EXCUSE ME.
PARDON ME.
COMING THROUGH.
OH. OH. SORRY.
SORRY! UM, JUST GOING...
DID WE GET IT, CLAIRE?
Claire nods and gives her the thumbs up.
Mikaela says AWESOME!
SO, WHERE ARE WE AT, CLAIRE?
Claire says EVERYTHING'S READY TO GO.
IT'S TIME TO FINISH YOUR VIDEO.
Mikaela says LET'S DO IT!
Claire says HOW DO YOU FEEL
ABOUT THIS SOUND?
(DOG BARKING)
Mikaela says GOOD.
Claire says ALL RIGHT.
Mikaela says WHY DON'T WE MOVE
THAT OVER THERE?
Claire says YEAH!
SHOULD WE BRING THIS UP A BIT?
(COW LOWING)
(ROOSTER CROWING,
DOG BARKING)
(CAT YOWLING)
Mikaela says I HAVE AN IDEA!
MOVE THAT OVER HERE.
(CAT YOWLING,
ROOSTER CROWING)
Mikaela says CLAIRE, I THINK IT'S READY!
(DRUM ROLL SOUNDING)
In animation, Mikaela takes the film to the screening room.
Claire says ALL RIGHT, THE VIDEO'S DONE.
Mikaela says AND NOW IT'S TIME
FOR MY FAVOURITE PART -
THE FINAL SCREENING.
BUT THERE'S ONE THING MISSING.
(POPCORN POPPING)
(FANFARE SOUNDING)
As a bucket of popcorn pops up in her hands, Mikaela says AHH. POPCORN.
ROLL IT, PLEASE!
Now the video rolls with all the sound effects.
Mikaela says WANT SOME POPCORN?
(BIRDS CHIRPING)
(CAR HORN HONKING)
(DOG BARKING)
(SIREN BLARING)
(FEET THUDDING)
(SKATEBOARD RATTLING)
(SLIDE WHISTLE TRILLING)
The skater says WHOA! SORRY, DUDE!
(CAR HORN HONKING)
(SIREN SOUNDING)
Mikaela says EXCUSE ME. PARDON ME.
COMING THROUGH.
OH. OH, SORRY!
(CAT YOWLING)
(LAUGHING)
The video ends.
Claire says BRAVA!
Mikaela says BRAVA!
Back in her studio, Mikaela says WASN'T THAT GREAT?
I LEARNED SO MUCH, AND NOW,
I'M PRETTY SURE
I WANNA BE A SOUND EDITOR...
(WHISPERING:) ...FOR NOW.
YOU GET TO WORK WITH
LOTS OF CREATIVE PEOPLE
TO FIGURE OUT HOW TO
MAKE VIDEOS SOUND AWESOME.
AND WHEN RECORDING GOES WRONG,
YOU GET TO SAVE THE DAY.
NOW I KNOW MY VIDEOS
WILL SOUND PERFECT.
FOR EXAMPLE...
As he drops the pen again, an explosion sound is heard.
(EXPLOSION BOOMING)
Mikaela says WELL, ALMOST PERFECT.
SEE YOU NEXT TIME ON...
In a goofy cartoon voice, Mikaela says WHEN I GROW UP!
(MUFFLED MUSIC PLAYING)
The end credits roll.
Teacher James says SO, TODAY, WE'VE LOOKED AT
WHAT KIND OF CAREER
YOU MIGHT BE ABLE TO
CONSIDER GOING WITH SOUND.
IF YOU THINK ABOUT A LOT OF THE
THINGS YOU'VE WATCHED
AND LISTENED TO AND LIKED,
SOUND IS OFTEN
HALF THE EXPERIENCE
IN THINGS LIKE MOVIES,
TELEVISION, VIDEOS,
AND THERE'S A
WHOLE LOT OF HARD WORK
THAT DOESN'T GET NOTICED.
WE ALSO LEARNED THAT PITCH AND
SOUND IS MEASURED IN HERTZ
AND THAT CAN DESCRIBE WHAT OTHER
PEOPLE AND ANIMALS HEAR.
WE'VE LOOKED AT SOME WAYS
THAT YOU CAN USE SOUND
AND LOOK AT IT AND VIEW IT,
JUST USING SOME THINGS AT HOME.
BUT MOST IMPORTANTLY,
YOU'VE, HOPEFULLY,
GOT A NUMBER OF GOOD QUESTIONS
THAT YOU'RE CURIOUS ABOUT
AND WANT TO ANSWER.
GOOD SCIENCE ISN'T ABOUT
TRICKS AND SPECTACLE.
ALTHOUGH, TRICKS AND
SPECTACLE IS FUN.
BUT SCIENCE IS OBSERVABLE
AND REPEATABLE FACT
AND THAT'S FACT THAT'S UNCOVERED
BY CURIOUS PEOPLE LIKE YOU,
WHO ASK THE RIGHT QUESTIONS
AND FIND THE RIGHT ANSWERS.
THERE'S A LOT
GOING ON AT THIS MOMENT
THAT CAN BE PRETTY CONFUSING.
BUT IF YOU ASK
THE RIGHT QUESTIONS
AND BE PATIENT WHEN YOU DON'T
HAVE ALL THE ANSWERS RIGHT AWAY,
IN TIME, THINGS WILL START
TO MAKE A BIT MORE SENSE.
SO, STAY SAFE, BE WELL.
I AM SORRY WE HAVE TO GO NOW,
BUT YOU DON'T HAVE
TO STOP LEARNING.
Music plays as the end credits roll.
A caption reads "TVO Kids would like to thank the following volunteer teachers for teaching the children of Ontario from their homes: James Bambury, Kenisha Bynoe, Spencer de Man, Joel Seaman, Kristy Tait Angel, Vickita Bhatt, Amanda Cameron, Arianna Lambert, Cameron Steltman and Robert Vidler."

The caption changes to "Today's Junior lesson: seeing sound."
Laura says WELCOME TO
TVOKIDS
POWER HOUR OF LEARNING.
TODAY'S JUNIOR LESSON:
SEEING SOUND.
A caption reads "Junior 4 to 6. Teacher James."
James is in his forties, with short gray hair and a beard. He wears a blue T-shirt.
He says HELLO. WELCOME TO
THE TEACHER POWER HOUR.
I'M TEACHER JAMES AND
I AM SO GLAD YOU'RE HERE.
TO GET THE MOST
OUT OF OUR TIME TODAY,
THERE'S A FEW THINGS
YOU SHOULD GET YOURSELF.
A FEW OF THE EXPERIMENTS
THAT YOU SEE,
YOU CAN ACTUALLY DO AT HOME,
EITHER NOW OR LATER.
YOU'RE GONNA WANT
SOMETHING TO WRITE WITH
AND SOMETHING TO WRITE ON.
A PEN, PENCIL, MARKER IS FINE.
SAME WITH SOME PAPER,
A NOTEBOOK.
AND IF YOU HAVE SOME
OF THESE THINGS AROUND,
FOR NOW OR LATER,
THAT WOULD ALSO HELP.
He shows a list and says SO, SOMETHING LIKE PLASTIC WRAP,
A BOWL OR CONTAINER,
SALT OR SOME OTHER POWDER,
A LASER POINTER,
SOME TAPE,
AN ELASTIC BAND, A BALLOON,
A PHONE OR DEVICE
THAT PLAYS MUSIC,
A SPEAKER OR AN EARBUD,
AND MAYBE YOU WANT TO GET, LIKE,
A DRINK OR A SNACK HANDY.
TODAY, WE'RE GOING
TO LOOK AT SOUND.
OR SHOULD I SAY LISTEN TO SOUND?
WELL, YES, NO.
YOU'LL SEE.
NOW, WE TALKED ABOUT GETTING
OUR MIND READY TO LEARN,
BUT DID YOU KNOW
THAT ASKING QUESTIONS
IS ONE WAY YOU CAN REALLY
ENGAGE YOUR MIND
MUCH MORE WHEN YOU'RE LEARNING.
WHEN YOU LEARN SOMETHING NEW,
IT'S NOT THE END OF SOMETHING,
BUT IT SHOULD BE THE PROMPT
TO ASK MORE QUESTIONS.
IT GETS YOUR MIND
PROCESSING IN SOME WAYS.
I'D LIKE YOU, RIGHT NOW,
TO TRY TO WRITE DOWN - IF YOU'VE
GOT YOUR PENCIL AND PAPER -
WRITE DOWN THE FIRST TWO
OR THREE QUESTIONS YOU CAN THINK
OF TO DO WITH SOUND.
NOW, TO HELP YOU,
YOU MAY HAVE SEEN SOMETHING
LIKE THIS BEFORE -
A 'Q CHART'.
He shows a chart with question words and says NOW, IF WE TAKE THE MOSTLY
'W' WORDS OVER HERE...
OVER HERE,
AND THEN ADD THAT TO
ONE OF THE STEMS AT TOP,
THAT BECOMES THE
START OF A QUESTION.
YOU DON'T NEED TO
COPY THIS DOWN OR ANYTHING,
BUT IF YOU'RE WATCHING THIS
ON RECORDING LATER
OR HAVE ONE OF THOSE TVS
WHERE YOU CAN DO THAT,
MAYBE YOU JUST WANNA
PAUSE IT RIGHT NOW
AND USE THAT TO HELP YOU TO
COME UP WITH SOME QUESTIONS.
SO, NOW THAT MAYBE YOU'VE GOT A
QUESTION OR TWO ABOUT SOUND,
LET'S LOOK AT A PROBLEM.
He grabs his phone and says I'VE GOT A DEVICE HERE
THAT CAN MAKE SOME NOISE.
IT'S GOT A SMALL
SPEAKER UP THERE.
BUT IF I WANT TO LISTEN TO IT,
AND SAY I DON'T HAVE EARBUDS
OR I WANT MORE
PEOPLE TO HEAR IT,
IT'S NOT GONNA BE
TERRIBLY LOUD OR CLEAR.
SO, OTHER THAN ATTACHING THIS
TO SOME KIND OF SPEAKER
OR AMPLIFIER, WHAT CAN WE DO?
WHAT SORT OF THINGS DO YOU
THINK YOU MAY EVEN HAVE
AROUND YOUR ROOM OR
YOUR HOME RIGHT NOW
THAT COULD DO THIS?
KEEP THIS QUESTION IN YOUR MIND,
AS YOU SEE HOW THIS CHALLENGE
IS GONNA BE ANSWERED
ON
SCIENCE MAX,
AS THEY TRY TO FIND
THE LOUDEST SOUND.
An episode of "Science Max" rolls.
A group of young scientists appear doing a series of science experiments.
Phil is in his thirties, clean-shaven and with short curly dark blond hair. He wears gray trousers, a blue T-shirt and a yellow lab coat.
Phil says HAVE YOU EVER DONE
A SCIENCE EXPERIMENT
AND WONDERED WHAT IT WOULD BE
LIKE IF YOU DID IT BIG?
I HAVE.
(LAUGHING)
Phil appears under the water, in a skydiving chamber and on a trolley.
He says WHOA!
(SCREAMING)
MY NAME IS PHIL
AND I TAKE YOUR EVERYDAY
SCIENCE EXPERIMENTS
AND DO THEM BIG.
THIS IS
SCIENCE MAX:
EXPERIMENTS AT LARGE.
The logo of the show appears. It's a black and yellow triangle with an exploding element inside and a blue sign across that reads "Experiments at Large."
Voices shout SCIENCE MAX!
Clips from today's show roll.
Phil says TODAY'S
SCIENCE MAX
IS ALL ABOUT SOUND.
WE BEND THE POWER
OF SOUND TO OUR WILL
BY MAKING THE
LOUDEST SOUND WE CAN.
He says to a girl scientist WAIT A MINUTE.
A SUBWOOFER?
She says SUBWOOFER.
Phil says MAKE CORN STARCH MUD DANCE,
GLASSES BREAK,
AND THINGS VIBRATE.
Sal is in his thirties, clean-shaven and with short side parted dark blond hair. He wears glasses, jeans, an orange shirt and a brown tweed blazer.
Sal makes a floatie vibrate and screams.
(SCREAMING)
Phil says IT'S THE SOUNDS OF SCIENCE,
TODAY ON
SCIENCE MAX:
EXPERIMENTS AT LARGE.
Very quietly, Phil says GREETING SCIENCE
MAXIMITES AND WELCOME TO...
CAN YOU HEAR ME?
GREETINGS SCIENCE MAX...
YOU CAN'T.
HOLD ON A SECOND.
He turns up the TV volume and says GREETINGS, SCIENCE...
YEAH, THAT'S MUCH BETTER.
GREETINGS, SCIENCE MAXIMITES
AND WELCOME TO
SCIENCE MAX:
EXPERIMENTS AT LARGE.
TODAY, WE'RE GONNA BE
TALKING ABOUT SOUND.
SOUND IS ALL AROUND US.
WE USE IT EVERY DAY,
BUT WHAT IS IT REALLY?
SOUND IS ENERGY.
LET'S SAY THAT THIS IS THE...
THAT THIS...
He pulls down a projection screen and it rolls back up.
He says NO, STAY.
STAY. OKAY...
He stretches a spring across the screen and says THAT THIS SPRING IS
THE SOUND OF MY VOICE.
WHEN I MAKE NOISE, IT TRAVELS
AWAY FROM ME IN A WAVE.
ONE AIR MOLECULE VIBRATES
THE NEXT AIR MOLECULE,
VIBRATES THE NEXT
AND IT LOOKS LIKE A WAVE,
AND WHEN THERE'S
A LITTLE BIT OF ENERGY
THE WAVE DOESN'T MOVE VERY MUCH.
SCIENCE.
BUT WHEN THERE'S A LOT OF
ENERGY, THE WAVE MOVES A LOT.
SCIENCE!
WHAT DO WE DO-- WHAT DO...
WHAT DO WE DO...
TO MAKE SOUND LOUDER?
He plays the show's theme song on his phone and says THIS IS THE
SCIENCE MAX THEME SONG,
BUT IT'S NOT VERY LOUD,
BECAUSE THE SPEAKER ON
MY PHONE ISN'T DESIGNED
TO MAKE SUPER LOUD NOISES.
SO, WHAT WE'RE GOING TO DO
IS FIND WAYS TO MAKE
THE VOLUME OF THAT SONG
AS LOUD AS POSSIBLE.
HERE IS ONE WAY.
TAKE A PHONE PLAYING SOME MUSIC
AND PUT IT IN A GLASS.
MAKE SURE THE GLASS
IS EMPTY, OF COURSE.
(MUSIC PLAYING LOUDER)
He puts it in and out of the glass and says HUH?
AND SUDDENLY, IT'S A LOT LOUDER.
(MUSIC PLAYING QUIETER)
(MUSIC PLAYING LOUDER)
WOW!
(MUSIC PLAYING QUIETER)
(MUSIC PLAYING LOUDER)
WHY THIS WORKS
IS ONE OF THE THINGS WE'RE
GOING TO BE LOOKING AT TODAY.
SO, WHAT'S WHAT WE'RE
GONNA DO TODAY
ON
SCIENCE MAX:
EXPERIMENTS AT LARGE -
WE'RE GONNA LEARN HOW
TO MAKE SOUND LOUDER,
AS LOUD AS WE CAN.
BUT I'M GONNA NEED
AN EXPERT TO HELP ME.
He throws a lab coat on and enters a portal.
He says OH! I KNOW! MIKAELA FROM
THE ONTARIO SCIENCE CENTRE.
SHE'S VERY SMART.
ALL I NEED TO DO IS GO TO
THE ONTARIO SCIENCE CENTRE
AND SEE IF SHE'S BUSY.
He slides down a slide on the other side and says AH!
Mikaela is in her twenties, with long straight brown hair in a ponytail. She wears black jeans, a purple top and a white lab coat.
She says PHIL! ARE YOU OKAY?
Phil says YEAH! MIKAELA!
IT'S GOOD TO SEE YOU.
Mikaela says NICE TO SEE YOU TOO.
Phil says THAT WAS WEIRD.
I WAS WONDERING IF YOU
COULD GIVE ME A HAND
WITH AN EXPERIMENT?
Mikaela says OH! I'D LOVE TO. YEAH.
Phil says IT'S A SOUND EXPERIMENT.
Mikaela says SOUNDS AWESOME.
Phil says RIGHT ON!
OKAY! WE'LL TAKE THE PORTAL.
WE'LL GO BACK
TO SCIENCE MAX HEADQUARTERS.
Mikaela says OH! WE GET TO TAKE
THE PORTAL! COOL!
Phil says HAVEN'T YOU TAKEN
THE PORTAL BEFORE?
Mikaela says NO, DON'T YOU REMEMBER?
IT WASN'T WORKING LAST TIME.
Phil says OH! WELL, IT'S...
Mikaela says IS IT WORKING?
Phil says FIXED THIS TIME.
YEAH, NO, IT'LL BE GREAT.
TRUST ME. HERE WE GO.
They pop up in a warehouse.
Mikaela says WHOA.
WHAT'S GOING ON, PHIL?
IS EVERYTHING OKAY?
Phil says USUALLY WHEN I COME THROUGH
THE PORTAL,
I LAND ON SOMETHING OR
SOMETHING FALLS ON ME OR...
Mikaela says NOT TODAY!
Phil says IT'S YOUR LUCKY DAY.
I GUESS SO.
Mikaela says SAFE LANDING! NICE!
Phil says SAFE LANDING!
HIGH FIVE! ALL RIGHT!
SO, LET'S GET STARTED...
Mikaela says OKAY, COOL.
(CRASHING)
Phil bumps into a big pile of plastic crates, they all fall and make a loud noise.
Now they stand behind a table with an empty glass.
Phil says THIS IS THE EXPERIMENT I WANT
TO MAX OUT TODAY, MIKAELA.
I KNOW.
PRETTY IMPRESSIVE, RIGHT?
NO, NO. HOLD ON.
(LAUGHING)
Phil says OKAY.
SO, I TAKE MY PHONE
AND I PLAY SOME
MUSIC ON MY PHONE.
(MUSIC PLAYING QUIETLY)
He puts the phone inside the AND...
(MUSIC PLAYING LOUDER)
Phil says IT'S LOUDER!
Mikaela says HEY! CHECK IT OUT!
Phil says RIGHT?
Mikaela says PHIL, YOU'VE JUST MADE YOURSELF
A RESONANCE CHAMBER.
Phil says A RESONANCE CHAMBER!
VERY NICE.
Mikaela says A RESONANCE CHAMBER
IS WHAT WE SAY
WHEN WE'RE TRYING TO DESCRIBE
HOW THE SOUND IS AMPLIFIED.
SO, IF THE SOUND IS COMING
IN FROM ONE DIRECTION,
IT'S BOUNCING AROUND,
NOT REALLY LOSING ENERGY,
SO WHEN MORE SOUND
COMES IN THAT'S AMPLIFIED,
WE HEAR IT A LOT LOUDER.
Phil says THAT'S COOL. SO THAT'S
WHAT I WANT TO DO...
HOLD ON. LET ME TURN THIS OFF.
THAT'S WHAT I WANT TO DO TODAY.
I WANT TO MAX OUT AS MUCH
SOUND AS WE CAN GET
OUT OF THIS
SCIENCE MAX
THEME SONG...
Mikaela says OH! I'M SO EXCITED
Phil says WHICH IS TOTALLY AWESOME.
SO, WHAT ELSE CAN WE DO
TO DO THAT?
Mikaela says WELL, THERE'S A COUPLE
OF AVENUES, I'M THINKING.
DO YOU WANT TO TRY
SOMETHING WITH ELECTRICITY
OR WITHOUT ELECTRICITY?
Phil says BECAUSE WITH ELECTRICITY, WE'RE
TALKING SPEAKER SYSTEMS AND...
Mikaela says YEAH.
Phil says RIGHT.
SO, WHY DON'T WE DO
NO ELECTRICITY FOR NOW
AND THEN WE CAN JUMP
TO ELECTRICITY
WHEN WE FEEL WE'VE EXHAUSTED
EVERYTHING THAT NON-ELECTRIC?
Mikaela says COOL!
SO, I WAS THINKING WE COULD TRY
TO MAKE A MEGAPHONE,
BECAUSE IF WE
HAVE A LOT OF SOUND,
WE COULD, YOU KNOW,
FUNNEL IT IN ONE DIRECTION
AND THEN IT'LL BE LOUDER.
Phil says OKAY, YEAH!
Mikaela says WHAT DO YOU THINK?
Phil says SO, THE MEGAPHONE'S
PRETTY EASY TO MAKE, RIGHT?
WE CAN JUST USE-- IN FACT,
WE COULD USE THIS PIECE
OF PAPER, RIGHT?
Mikaela says YEAH! LET'S TRY IT.
She makes a cone out of the paper and says WHAT DO YOU THINK?
Phil says I THINK IT'S VERY MEGAPHONEY.
SCIENCE-TAPING IT UP.
OKAY, READY?
OKAY, TURN IT ON.
(MUSIC PLAYING QUIETLY)
I'LL PLAY IT.
AND... DOESN'T SOUND...
He points the megaphone at her and says BUT WHAT IF I DO THIS?
(MUSIC PLAYING LOUDER)
Mikaela says HEY! THERE IT IS!
I LOVE THAT SONG.
Phil says OH, YEAH?
YOU HEAR IT?
Mikaela says YEAH! OH, I HEAR IT.
OKAY!
(MUSIC PLAYING LOUDER)
Phil says SO, THAT WORKED
PRETTY WELL! SO...
Mikaela says YEAH, IT WORKS.
WORKS WELL.
Phil says SO, OKAY...
SO THIS IS PRETTY EASY, RIGHT?
YEAH.
Phil says MEGAPHONE?
Mikaela says OH, YEAH!
Phil says SO, WHY DON'T WE MAX THIS OUT?
WHY DON'T WE MAKE
A GIANT MEGAPHONE
AND SEE IF IT MAKES
A BIG DIFFERENCE?
Mikaela says I THINK IT WILL.
He says over the megaphone SOUNDS GOOD!
LET'S GET STARTED.
WAHOO!
The Science Max logo appears under a magnifying glass.
A high-pitched voice says MINI MAX!
(BANGING)
Phil now bangs two trash can lids together and says ALL SOUND IS VIBRATION,
BUT IT'S REALLY HARD...
(CRASHING)
IT'S REALLY HARD TO LEARN
ABOUT THAT VIBRATION
IF YOU CAN'T SEE IT.
I MEAN, SOUND IS
INVISIBLE, RIGHT?
WELL, HERE'S A WAY
THAT YOU CAN MAKE SOUND VISIBLE.
ALL YOU NEED IS
SOME PLASTIC WRAP
AND SALT AND A BOWL.
JUST A REGULAR BOWL.
AND AN ELASTIC LIKE THIS.
SO, WHAT YOU DO IS YOU
TAKE THE PLASTIC WRAP
AND CUT OFF A PIECE
JUST LARGE ENOUGH
TO FIT OVER THE BOWL
AND THEN USE THE ELASTIC
TO WRAP AROUND THE BOWL
TO KEEP THE PLASTIC TIGHT.
POUR SOME SALT ON THE BOWL
AND THEN WATCH THIS.
He gets closer to the bowl and says in a loud voice HELLO!
VIBRATING SALT!
THE PLASTIC WRAP IS STRETCHED
TIGHT OVER THE BOWL
MAKING IT LIKE A DRUM,
A DRUM THAT'S VERY SENSITIVE
TO SOUND VIBRATIONS.
YOUR EAR WORKS THE SAME WAY.
THAT'S WHY WE CALL IT
AN EARDRUM.
THE VIBRATIONS FROM MY VOICE
MAKE THE PLASTIC WRAP VIBRATE
AND THAT MAKES THE SALT DANCE.
BUT THERE'S MORE!
LET'S MAX THIS OUT.
THIS IS A CHLADNI PLATE
AND WHAT IT IS, IS JUST A PIECE
OF METAL ON A PLATFORM
THAT VIBRATES UP AND DOWN
TO A FREQUENCY,
WHICH I CAN PROGRAM
WITH THIS DIAL HERE.
AND WHEN THE SOUNDWAVES
VIBRATE THE PLATE,
THEY CAN INTERACT IN WAYS
THAT MAKE THE SAND FORM
INTERESTING PATTERNS.
TAKE A LOOK.
(HIGH FREQUENCY TONE)
He pours salt on the platform and says THE SOUNDS THAT I'M GENERATING
VIBRATE THE PLATE,
MAKE IT MOVE LIKE A WAVE,
BUT WHEN THE VIBRATIONS REACH
THE EDGE OF THE PLATE,
THEY BOUNCE BACK
AND INTERACT WITH THE OTHER
WAVES GOING THE OTHER WAY.
THE WAY THESE WAVES INTERACT
AT DIFFERENT NOTES
IS WHAT CAUSES THE SAND
TO MAKE
THESE DIFFERENT SHAPES.
SO, THIS IS GREAT,
BUT YOU KNOW WHAT?
WE CAN MAX IT OUT EVEN MORE.
MAXING IT OUT EVEN MORE!
(PITCH GETTING HIGHER)
AHH!
(PITCH GETTING HIGHER)
OKAY! THAT'S ABOUT AS MUCH
AS I CAN TAKE OF THAT. OH...
James says WELCOME BACK.
SO, WE CAN SEE THAT WHEN SOUND
HAS A CHANCE TO RESONATE,
IT CAN GET LOUDER AND FULLER.
IF WE WANT TO MAKE
A PHONE PLAY LOUDER
OR PERHAPS GET MORE
SOUND OUT OF EARBUDS,
WE'RE GONNA NEED SOME TYPE
OF RESONANCE CHAMBER.
FOR THIS, WE NEED AN ENCLOSED
SPACE AND A SMALL EXIT,
SO THAT SOUND CAN
BOUNCE AROUND INSIDE
AND THEN PRODUCE THE RESONANCE.
THINK OF IT A BIT LIKE,
YOU KNOW,
A GUITAR OR A UKULELE HERE.
THE SOUND CAN
BOUNCE AROUND INSIDE
AND IT'S GOT
THE MATERIAL OF WOOD
AND THEN IT'S GOT THE SMALL HOLE
WHERE THE SOUND
CAN THEN COME OUT.
AND, YOU KNOW, SO, THE LARGER
THE RESONANCE CHAMBER,
THE MATERIALS, ALL CHANGE THE
QUALITY OF THE SOUND THERE.
NOW, WHAT KIND OF
QUESTIONS DO YOU HAVE?
DID YOU ASK HOW
A MEGAPHONE WORKS?
OR WHAT WOULD HAPPEN
IF THE MEGAPHONE WERE OF
DIFFERENT MATERIAL?
DID YOU ASK, "SHOULD I MAKE MY
OWN DRUM OF PLASTIC WRAP
"AND WITH A BOWL AND SOME SALT
OR SOMETHING TO SEE THE SOUND?"
WELL, THE ANSWER IS
YES, YOU SHOULD.
I'VE GOT...
AND I'VE GOT THAT HERE NOW.
I'VE TAKEN A BOWL
AND INSTEAD OF SALT,
I'VE GOT SOME ORANGE
DRINK CRYSTALS ON TOP OF IT.
AND LET'S SEE SOME SOUND.
OKAY, SO, I'VE GOT
THE POWDER SET UP.
I'VE MADE KIND OF A DRUM.
NOW, IF I JUST MAKE SOME NOISE,
YOU KNOW,
WITH MY LIPS HERE, JUST LIKE...
(BLOWING RASPBERRY)...YOU DON'T SEE ANY EFFECT.
BUT IF I ADD, SAY, A BIT MORE
RESONANCE TO THAT,
LIKE, SAY, MY VUVUZELA HERE...
I'M GONNA PLAY THIS
AND I'M GONNA KEEP THE BELL
OF THAT ACROSS HERE.
SO, YOU'LL KNOW IT'S
NOT THE WIND OR ANYTHING
MOVING THESE AROUND.
LET'S OBSERVE WHAT HAPPENS.
He plays the vuvuzela and the salt starts moving out of the bowl.
(HORN BLARING)
(HORN BLARING)
James says WHEN WE WERE
DOING THAT JUST NOW,
I WAS PLAYING THE VUVUZELA
AND THE VIBRATIONS FROM THAT
WERE THEN CAUSING
THE BOWL TO SHAKE
AND THAT WAS MAKING
THE PLASTIC WRAP SHAKE
AND THAT WAS MAKING THE DRINK
CRYSTALS ON THERE
START TO KIND OF
BOUNCE UP AND DOWN,
LIKE IT WAS A TINY TRAMPOLINE
AND THEY STARTED TO MOVE OFF
BECAUSE I HAD IT TILTED UP.
SO, WE CAN SEE THAT SOUND CAN
HAVE-- EFFECT THINGS PHYSICALLY
AND IT'S NOT JUST THIS
OTHER THING WE HEAR,
BUT IT IS PART OF
THE PHYSICAL WORLD ITSELF.
NOW, IF YOU STARTED TO
MAKE YOUR OWN AMPLIFIER,
YOU MIGHT WANT TO SEE WHAT KIND
OF CHANGES YOU CAN MAKE
IN THE MATERIAL YOU USE,
WHETHER INSIDE OR OUTSIDE,
THE SIZE AND SHAPE OF THE
RESONANCE CHAMBER,
THE SIZE AND SHAPE OF
THE EXIT FOR IT.
ALL THOSE VARIABLES,
IF YOU ALTER THEM,
IT WILL HAVE SOME
EFFECT ON THE SOUND.
NOW, IN KEEPING WITH GOING TO
THE NEXT LEVEL WITH DESIGN
AND TRYING TO CHANGE THINGS UP,
LET'S CHECK IN ON HOW THE QUEST
FOR THE LOUDEST SOUND
IS GOING WITH
SCIENCE MAX.
Phil says SO, MIKAELA
AND I ARE ON A QUEST
TO MAKE
THE LOUDEST SOUND WE CAN.
THE FIRST STEP IS
TO MAKE THINGS LOUDER
WITHOUT USING ELECTRICITY.
WE'VE LOOKED AT
A RESONANCE CHAMBER
AND NOW WE'RE GOING TO MAKE
A LARGE MEGAPHONE.
SOUNDS CAN BE AMPLIFIED
BY BOUNCING SOUNDWAVES
AROUND IN A SPACE.
WHEN I PUT MY PHONE
INTO THE GLASS,
THE GLASS ACTS AS
A RESONANCE CHAMBER.
THE SOUNDWAVES BOUNCE
AROUND INSIDE THE GLASS
AND THEY COMBINE AND STACK
ON TOP OF EACH OTHER.
THIS MAKES THE SOUND LOUDER.
RESONANCE CHAMBERS ARE USED
BY MUSICAL INSTRUMENTS,
LIKE AN ACOUSTIC GUITAR.
THE WOODEN CHAMBER BOUNCES
THE SOUNDWAVES AROUND
AND THE SOUNDWAVES
BUILD ON EACH OTHER
TO MAKE THE SOUND LOUDER.
A MEGAPHONE BOUNCES
SOUNDWAVES AS WELL.
INSTEAD OF GOING OFF
IN ALL DIRECTIONS,
A MEGAPHONE MAKES THE
SOUNDWAVES
ALL GO IN ONE DIRECTION.
THAT'S ONE OF THE REASONS
WHY A MEGAPHONE
MAKES SOUNDS LOUDER.
BUT ONLY WHEN IT'S
POINTED AT YOU.
SO, WILL A BIGGER
MEGAPHONE WORK BETTER?
SO, WE'VE MADE
A LARGER MEGAPHONE,
WHICH IS EXACTLY THE SAME THING.
YOU JUST TAKE A SHEET
AND YOU ROLL IT UP,
EXCEPT OUR SHEET WAS
PLEXIGLAS COVERED IN PAPER,
AND WE'VE TAPED IT
TOGETHER SO IT STAYS,
AND THE IDEA HERE...
Mikaela says OH, YEAH. BIGGER MEGAPHONE.
WE'RE GONNA VIBRATE EVEN MORE
OF THE AIR INSIDE OF HERE
AND HOPEFULLY,
THIS THING WILL BE LOUDER.
Phil says OKAY, SO YOU'RE READY TO
TRY IT WITH THE PHONE?
Mikaela says YEAH!
Phil says I THINK FIRST,
WE SHOULD TRY IT WITH
OUR VOICES, THOUGH.
Mikaela says OKAY!
They stand at a distance from each other,
Mikaela says through the megaphone HEY, PHIL, WHAT'S YOUR
FAVOURITE SEASON?
Phil says AWESOME! I CAN TOTALLY
HEAR YOU! THAT'S AMAZING!
Mikaela says CAN YOU REALLY?
Phil says AND IT WOULD BE FALL.
NAH! SUMMER!
UH, SPRING?
Mikaela says THINK ABOUT IT.
Phil says ANYTHING BUT WINTER.
SO, THE MAXED-OUT
MEGAPHONE WORKED,
BUT WE STILL HAD TO
TRY IT WITH MY PHONE.
OKAY.
Mikaela says ALL RIGHT.
(MUSIC PLAYING QUIETLY)
(MUSIC PLAYING LOUDLY)
Phil says YEAH?
Mikaela says OH, YEAH!
(MUSIC PLAYING LOUDLY)
OH, DEFINITELY.
He moves the phone further from the megaphone and says HOW ABOUT NOW?
(MUSIC PLAYING QUIETLY)
Mikaela says NO, NOT SO MUCH.
NOT SO MUCH.
Phil moves the phone closer to the megaphone.
(MUSIC PLAYING LOUDLY)
Mikaela says OH, YEAH!
(MUSIC PLAYING QUIETLY)
Mikaela says NO, NO.
Phil says SO, THAT IS A...
THAT WAS COOL... GREAT EXAMPLE OF
NON-ELECTRICAL AMPLIFICATION.
Mikaela says THAT'S RIGHT.
Phil says AMPLIFIED THE SOUNDS.
NO ELECTRICITY.
OKAY! HIGH FIVE!
Mikaela says SWEET!
Phil says ALL RIGHT.
Now a neon sign appears that reads "Sal's Science Shop."
Sal says COME ON!
MAKE SOME NOISE!
(JAZZY SAXOPHONE MUSIC PLAYING)
Sal dances and says WELL, HOW DO YOU MAKE NOISE?
WELL, TO KNOW THAT,
YOU GOTTA KNOW YOUR SOUND.
HEY!
(JAZZY SAXOPHONE MUSIC PLAYING)
ALL SOUND IS VIBRATION.
(GUITAR STRUMMING)
He grabs a guitar and says HERE! TAKE A CLOSER LOOK.
YOU SEE? WE'VE GOT...
He falls over the counter and says WHOA!
OKAY, LET'S TRY THIS AGAIN.
ALL SOUND IS VIBRATION.
(NOTE SOUNDING)
Sal says THE STRING OF
THIS GUITAR VIBRATES,
WHICH VIBRATES
THE AIR AROUND IT,
CAUSING THE SOUND THAT YOU HEAR.
YOUR VOCAL CORDS
VIBRATE IN YOUR THROAT,
CAUSING YOU TO MAKE A SOUND.
(GUITAR STRUMMING)
AH!
(GUITAR STRUMMING)
AH!
(GUITAR STRUMMING)
AH!
LA-LA-LA-LA-LA-LA-LA
He pulls out a floatie and says LOOK AT THIS THING!
LOOK AT THIS THING!
SEE HOW
IT'S SHAKING BACK AND FORTH?
IT'S VIBRATING.
THINGS THAT
MAKE A HIGH SOUND...
(DINGING)...
He plays a tringle and says THEY VIBRATE FASTER.
He makes the floatie vibrate more and says VIBRATING REALLY FAST.
WAH!
THINGS THAT MAKE A LOW SOUND
VIBRATE SLOWLY.
(TUBA PLAYING)
He moved the floatie really slowly and says AH!
HIGH NOTE!
(DINGING)
VIBRATING FAST.
FAST!
(RINGING)
In a low pitch, he says WHOA!
(GUITAR STRUMMING)
LA!
FAST VIBRATING!
(LOW NOTE SOUNDING)
He bangs a gong.
He says SLOW!
AND NOW YOU KNOW YOUR SOUND!
(RINGING)
He bangs the gong again and breaks it.
(CRASHING)
The caption changes to "Max Fax!"
Phil stands behind a fish tank and says EVERYTHING HAS A RESONANCE -
A NOTE THAT IT VIBRATES BEST AT.
LET'S SAY THIS
FISH TANK IS, WELL,
ANY CONTAINER WHERE SOUND
WOULD BE VIBRATING
AND THE WAVES OF WATER
ARE ACTUALLY WAVES OF SOUND.
NOW, NORMALLY,
SOUND WAVES WILL BOUNCE AROUND
INSIDE THE CONTAINER,
OFF THE WALLS,
AND GO BACK AND FORTH LIKE THAT.
AND HOW FAST I MOVE
THIS PIECE OF WOOD
IS THE FREQUENCY
OR THE NOTE THAT WE'RE PLAYING.
I COULD VIBRATE
THIS WOOD VERY FAST
AND MAKE A HIGH NOTE.
I COULD MOVE THIS PLANK VERY
SLOW AND MAKE A LOW NOTE.
AND THE WAVES JUST BOUNCE
AROUND INSIDE THE CONTAINER.
BUT THERE'S A SPEED
I CAN MOVE THIS PLANK
WHERE THE WAVES STOP
GOING SIDE TO SIDE
AND SUDDENLY GET TWICE AS BIG.
THE WAVES BOUNCING
OFF THE SIDES OF THE TANK
ARE MEETING THE WAVES GOING
IN THE OTHER DIRECTION,
BUT WHAT WE END UP SEEING
IS PEAKS OF THE WAVES
NOT MOVING SIDE TO SIDE,
JUST GOING UP AND DOWN
LIKE YOU SEE HERE.
THIS IS THE RESONANCE
FREQUENCY OF THIS CONTAINER.
SO, LET'S MAX THIS OUT.
SAY I HAVE A WINE GLASS
AND I WET MY FINGER
AND I RUB IT
AROUND THE RIM.
(GLASS RINGING)
IT VIBRATES AT A CERTAIN NOTE.
THAT NOTE IS THE
RESONANT FREQUENCY
OF THIS WINE GLASS.
SO, WHAT WOULD HAPPEN
IF WE WERE TO PLAY THAT NOTE
BACK TO THIS WINE GLASS
REALLY, REALLY LOUD?
(NOTE RESONATING)
He uses and amplifier to amplify the note and AND YES, THIS IS SOMETHING
YOU SHOULD NOT TRY AT HOME.
THIS NOTE MAKES
THE GLASS VIBRATE THE MOST.
FINDING THE PERFECT NOTE
THINGS VIBRATE BEST AT
IS GREAT FOR
MUSICAL INSTRUMENTS,
BUT IT'S NOT GREAT FOR
THIS WINE GLASS.
THE SOUNDWAVES ARE CAUSING
THE GLASS TO VIBRATE A LOT
AND BECAUSE THIS GLASS
IS DELICATE,
IT CAN ONLY VIBRATE SO MUCH
BEFORE IT BREAKS.
(NOTE RESONATING)
The glass cracks and breaks.
(CRACKING)
(NOTE RESONATING)
THE VIBRATIONS WERE SO STRONG
THAT THE GLASS LITERALLY
SHOOK ITSELF TO PIECES.
(LAUGHING)
He says SCIENCE!
He takes off his earmuffs and says SORRY-- SCIENCE!
OH, WAIT.
He takes off his earplugs and says SCIENCE.
James says SO, UH, I LIKE TO THINK
THAT, AFTER THAT,
YOU MIGHT HAVE SOME MORE
QUESTIONS YOU MIGHT WANT TO ASK.
MAYBE SOMETHING LIKE,
"HOW CAN SOUND BREAK GLASS?"
OR ABOUT HOW A
RESONANCE CHAMBER WORKS.
LET'S THINK BACK TO THE EXAMPLE
WITH HOW IT FOCUSES SOUND.
WELL, LET'S LOOK AT THIS
INSTRUMENT HERE -
A JAW HARP.
IF YOU JUST PLUCK THE METAL...
(PLINKING QUIETLY)...YOU DON'T REALLY
HEAR ANYTHING.
THE RESONANCE CHAMBER HAPPENS
BY USING YOUR MOUTH AS ONE.
UH...
SO, I JUST PUT IT IN
MY TEETH AND PLUCK IT.
(PLINKING QUIETLY)
WELL, IT'S MUCH LOUDER TO ME
BECAUSE I'M HEARING IT
THROUGH MY TEETH AND BONE
RIGHT INTO MY EARDRUM.
BUT IT PROBABLY DOESN'T
SOUND MUCH DIFFERENT FOR YOU.
SO, IN ORDER TO TAKE THE
NEXT STEP WITH THIS,
I'M GONNA THEN BREATHE OUT
WHILE I'M PLUCKING IT,
AND LET'S HEAR THE
DIFFERENCE THAT MAKES.
(BREATHING HEAVILY,
NOTE SOUNDING)
SO, SOMETIMES, THE SOUND NEEDS A
MEDIUM FOR IT TO BE CLEAR.
YOU CAN GET A SIMILAR
IDEA OF WHAT HAPPENED -
'CAUSE YOU PROBABLY DON'T
HAVE A JAW HARP AT HOME -
BUT JUST WITH A PEN OR PENCIL...
JUST IF YOU A PEN OR PENCIL,
JUST KIND OF SCRATCH IT OR...
KIND OF FLICK THE EDGE OF IT
THERE AND YOU WON'T HEAR MUCH.
BUT IF YOU PUT THIS
SO IT'S ON A TABLE
AND SIT YOUR EAR
RIGHT DOWN THE TABLE,
DO THE SAME THING AND LISTEN
FOR THE DIFFERENCE.
NOW THAT IT'S GOT THAT
MEDIUM TO TRAVEL THROUGH,
IT SHOULD SOUND A LOT
LOUDER AND FULLER
AND SIMPLY SCRATCHING THE PENCIL
CAN SOUND LIKE SOMEBODY...
SOMEBODY SAWING LOGS...
RIGHT NEAR YOU.
SO, YOU MAY WANT
TO THINK ABOUT THIS.
AND DO YOU HAVE ANY
NEW QUESTIONS?
YOU KNOW, PEOPLE HAVE BEEN
ASKING QUESTIONS ABOUT SOUND
FOR AN INCREDIBLY LONG TIME.
OVER 150 YEARS AGO,
IN THE MID-1800S,
A FRENCH INVENTOR -
EDOUARD-LÉON SCOTT -
WAS TRYING TO LOOK AT WHAT
SOUNDS LOOKED LIKE
AND HE WANTED TO KNOW HOW THEY
WERE DIFFERENT FROM ONE ANOTHER.
AND SO, HE MADE A DEVICE THAT,
WHEN IT HEARD SOME SOUND,
IT WOULD MOVE A TINY NEEDLE,
AND IF YOU MOVED PAPER UNDER IT
WHILE SOME NOISE WAS HAPPENING,
IT SORT OF WIGGLED AROUND
AND IT MADE SOMETHING
CALLED A PHONAUTOGRAM.
He shows a picture of transcribed sound waves.
He says AND SO...
EDOUARD SCOTT SANG THE SONG
"AU CLAIR DE LA LUNE."
AND WOUND UP CAPTURING
THE FIRST EVER AUDIO RECORDING.
EXCEPT, HE DIDN'T REALLY
KNOW IT AT THE TIME.
HE REALLY DIDN'T THINK
THERE WAS EVER GONNA BE A WAY
TO PLAY BACK SOUNDS.
HE WAS JUST HAPPY TO SEE
AND OBSERVE THAT THEY
COULD BE DIFFERENT.
SO, JUST TO GIVE YOU AN IDEA
'CAUSE THIS IS A COPY OF HIS... ..THAT THIS WOULD HAVE BEEN
ROLLED UP INTO A CYLINDER... ..AND THEN PLAYED
AND THEN TURNED OVER...
ROLLED UP INTO A CYLINDER
AND THEN TURNED OVER,
AS THE NEEDLE THEN MADE ALL THE
DIFFERENT IMPRESSIONS ON IT.
RIGHT THERE.
NOW, UH...
PAY ATTENTION IN
THE NEXT SEGMENT HERE,
WHEN YOU HEAR THE WORD "HERTZ."
HERTZ IS A FANCY AND PRECISE
WAY OF MEASURING PITCH.
IF YOU'VE EVER PLAYED
A MUSICAL INSTRUMENT
OR TAKEN ANY MUSIC LESSONS,
YOU'LL KNOW THAT NOTES
MAY HAVE DIFFERENT NAMES -
C, D, E, F, G,
B-FLAT.
AND YOU MAY EVEN THINK
OF THEM AS GOING UP OR DOWN
IN TONES OR SEMITONES.
BUT HERTZ IS A WAY
OF GOING FURTHER THAN THAT.
THINK OF IT A BIT
LIKE TEMPERATURE.
YOU MAY SAY
IT'S COLD OR CHILLY
OR HOT OR SCORCHING OUTSIDE.
BUT YOU CAN ALSO
GET A THERMOMETER AND KNOW,
"OKAY, IT'S 28 DEGREES."
OR 15 DEGREES.
HERTZ WORKS THE SAME WAY,
EXCEPT RATHER THAN SAY
SOUND IS HIGH OR LOW,
WE CAN GIVE IT A
VERY PRECISE NUMBER,
AND THIS IS SOMETHING YOU'LL
WANT TO TAKE INTO CONSIDERATION
WITH THE LOUDEST SOUND.
AND THIS NEXT SEGMENT,
ONE QUESTION I HAVE
GOING INTO IT IS
"WHAT WOULD EDOUARD-LÉON SCOTT
"THINK OF WHAT IS
ABOUT TO HAPPEN."
Back to Science Max, Phil says MIKAELA AND I HAVE TRIED
A RESONANCE CHAMBER
AND A GIANT MEGAPHONE
TO MAKE SOUND LOUDER.
NOW, IT'S TIME TO MOVE ON TO
THE NEXT STEP OF THE PLAN -
USING ELECTRICITY TO HELP US
AMPLIFY SOUND
AND THAT MEANS SPEAKERS.
SO, SPEAKERS
THAT YOU HAVE AT HOME.
THREE DIFFERENT
SPEAKERS HERE, RIGHT?
THREE DIFFERENT CONES.
Mikaela says YEAH, THERE'S
A LOT GOING ON HERE.
Phil says SO, WHAT'S THE DEAL?
Mikaela says WELL, HERE AT THE BOTTOM,
WE HAVE A SUBWOOFER.
Phil says A SUB-- WAIT A MINUTE,
A SUBWOOFER?
Mikaela says SUBWOOFER.
Phil says SO, IT'S A WOOFER?
THE WORD IS "WOOFER"?
Mikaela says YEP!
Phil says OKAY, SO IT'S FOR DOGS. RIGHT?
Mikaela says NO! NO! A SUBWOOFER IS FOR LOW
NOTES HERE IN OUR SPEAKER.
Phil says AH!
Mikaela says AT THE TOP HERE,
WE HAVE A TWEETER.
Phil says SO, IT'S FOR BIRDS!
IT'S BIRDS, DOGS.
SO, LET ME GUESS.
LOW NOTES?
Mikaela says YEAH.
Phil says TWEETER IS HIGH NOTES?
Mikaela says YEAH! HIGH NOTES!
Phil says YEAH.
Mikaela says AND THEN WE HAVE THIS
GUY HERE IN THE MIDDLE
AND THAT'S CALLED
YOUR MID-RANGE SPEAKER.
Phil says OH, THAT'S NOT NEARLY
AS COOL A NAME.
NOW, WE HAVE SPEAKERS.
WE'VE TAKEN A LOOK OF THAT.
BUT WHY DON'T WE
TAKE ONE APART? RIGHT?
Mikaela says COOL!
YEAH! LET'S DO IT.
Phil says I'VE GOT THIS ONE HERE
THAT I SPILLED JUICE ON.
SO, IT DOESN'T WORK ANYMORE,
SO I'VE KIND OF TAKEN IT APART,
Mikaela says COOL!
Phil says SO, IT'S GOT...
Mikaela says OH, MAN,
THAT'S AWESOME.
Phil says OKAY, SO IT'S GOT
THE COVER.
THAT'S COOL.
SO, WHAT I FIND INTERESTING
IS THERE'S THE SPEAKER
AND THE WIRES, RIGHT?
BECAUSE IT'S ELECTRICAL
AMPLIFICATION,
BUT CHECK THIS OUT.
THIS IS JUST A RING
TO HOLD THAT ON
AND THE REST IS
JUST AN EMPTY BOX
WE KNOW WHAT THAT IS.
They both say RESONANCE CHAMBER!
Phil says THAT'S RIGHT,
SO THAT'S WHY IT'S AN EMPTY BOX.
Mikaela says LET'S TAKE THIS APART, TOO,
SEE WHAT'S GOING ON.
Phil says SO, THAT'S JUST...
THAT'S THE PAPER CONE, RIGHT?
SO, THAT'S THE...
LIKE, THAT'S THE DRUM, I GUESS.
IT'S LIKE EARDRUM,
THE THING THAT VIBRATES.
Mikaela says YES. YEAH.
THIS WHOLE THING VIBRATES.
THAT'S OUR ELECTROMAGNET.
WHEN WE TURN THIS ON, THE
ELECTROMAGNET GOES ON AND OFF
AND IT'S CAUSING
THIS WHOLE THING TO VIBRATE.
Phil says SO, THAT'S HOW IT WORKS.
IT'S THE ELECTRICITY TURNING
THE ELECTROMAGNET ON AND OFF
Mikaela says EXACTLY.
Phil says AND IT'S ON AND OFF,
ON AND OFF, ON AND OFF,
ON AND OFF, ON AND OFF,
AND IT MAKES IT VIBRATE
AT CERTAIN SPEEDS, RIGHT?
Mikaela says YEP.
Phil says HERTZ.
THE NUMBER OF TIMES IT
VIBRATES PER SECOND IS HERTZ.
WHAT WE COULD DO IS WE COULD
MAX IT OUT WITH THE SPEAKER
AND PLUG THE PHONE
IN THE SPEAKER,
BUT THIS STEP DOES NOT FEEL LIKE
SCIENCE MAX
TO ME,
BECAUSE ANYBODY
CAN DO THAT, RIGHT?
Mikaela says YEAH.
Phil says YOU CAN JUST TURN UP
YOUR TELEVISION RIGHT NOW
AND THAT'S PRETTY MUCH
THE SAME KIND OF THING.
WE NEED ELECTRICAL
AMPLIFICATION, BUT MAX IT OUT.
Mikaela says MAX IT OUT.
WHAT ARE YOU THINKING?
Phil says OKAY, SO I'VE GOT A FRIEND
AND HE'S GOT A STEREO
SYSTEM THAT HE BUILT,
HE PUT TOGETHER,
AND WHAT HE DOES IS HE
TOURS DIFFERENT CITIES.
SO, HE SAID HE'D BRING IT BY
SCIENCE MAX HEADQUARTERS.
Mikaela says WHAT?!
HE'S GONNA BRING IT HERE?!
Phil says WE'VE GOT TO GO OUTSIDE.
Mikaela says I CAN'T WAIT TO SEE THIS THING.
Phil says AND IT'S VERY LOUD,
SO WE HAVE TO GO OUTSIDE.
Mikaela says WHEN IS HE COMING?
Phil says UM... RIGHT NOW.
ALL RIGHT.
LET'S GO CHECK IT OUT.
The caption changes to "Max Fax!"
Phil says SEEING SOUND VIBRATIONS IS FUN.
THIS KIND OF SPEAKER
IS A SPECIAL KIND.
IT'S CALLED A SUBWOOFER,
WHICH IS DESIGNED TO
GIVE YOU THE LOW NOTES,
THE BIG RUMBLY BASE SOUNDS.
I TILT THE SPEAKERS
SO IT'S FACING UP
AND COVER IT WITH
BIG SHEETS OF PLASTIC WRAP,
WHICH I PUSH INTO THE CONE,
THEN TAPE IT
SO IT'S NICE AND SECURE.
THEN WHAT YOU NEED IS
SOME CORN STARCH MUD,
WHICH IS TWO PARTS CORN STARCH,
ONE PART WATER.
I'VE GOT SOME YELLOW CORN STARCH
AND SOME BLUE CORN STARCH.
THIS EXPERIMENT WORKS
THE BEST WITH LOW NOTES.
I'M PLAYING A TONE THROUGH THE
STEREO THAT IS VERY LOW.
HERE'S WHAT HAPPENS
WHEN I TURN UP THE VOLUME.
(LOW RUMBLING)
(LOW RUMBLING)
The corn starch mud starts jumping.
Phil says WHOA!
(LAUGHING)
(LOW RUMBLING)
IT'S ALIVE!
(LOW RUMBLING)
YOU SEE, CORN STARCH MUD
IS A SHEER THICKENING FLUID,
WHICH MEANS WHEN YOU IMPACT IT,
IT TURNS SOLID.
SO, THE VIBRATIONS
FROM THE SPEAKER CONE
ARE MAKING THE
CORN STARCH MUD IMPACT
AND THAT'S TURNING INTO A SOLID,
BUT THEN IT SORT OF ALSO
MELTS BACK INTO A LIQUID,
SO YOU GET LITTLE
COLUMNS OF CORN STARCH
COMING UP AND
FALLING DOWN AGAIN.
IT'S LIKE IT'S DANCING.
WHOA!
(LOW RUMBLING)
VISUAL SOUNDWAVES!
SCIENCE!
SO, MIKAELA AND I
ARE GOING TO MAX OUT SOUND.
TO DO THAT, WE NEED
A MAXED OUT SOUND SYSTEM!
They walk out to the parking lot.
Phil says THIS IS GOING TO BE AMAZING.
Mikaela says IT'S SO COOL!
Phil says THIS IS GONNA BE SUPER
MAXED SOUND EXPERIMENT.
THIS IS JAMES, MIKAELA.
Mikaela says HEY, JAMES! HOW ARE YOU?
James says NICE TO MEET YOU.
Phil says THANKS FOR COMING, BUDDY.
James is in his thirties, with his head shaven and wears jeans, a black T-shirt and a yellow lab coat.
James says NICE TO BE HERE.
Phil says SO, TELL US ABOUT
YOUR SPEAKER SYSTEM!
IT LOOKS A LOT LIKE A VEHICLE.
James says THIS IS MY AUDIO VAN.
IT'S GOT FOUR 15-INCH
SUBWOOFERS IN THE BACK,
IT'S GOT A WHOLE BUNCH
OF POWER TO POWER IT,
AND I'M GLAD TO BE HERE
TO LET YOU GUYS HEAR IT TODAY.
Phil says AWESOME!
SO, IF I HAVE A SPEAKER AT HOME,
LIKE A LITTLE SPEAKER LIKE THIS,
HOW MANY WATTS DO
YOU THINK THAT WOULD BE?
James says SOMEWHERE BETWEEN 15 AND 25.
Phil says 15 AND 25 WATTS.
James says YES.
Phil says AND YOU'VE GOT 4,000?
James says YES.
Phil says SO, THAT'S A LOT MORE.
YEAH, IT'S QUITE A BIT.
Phil says AND SUBWOOFER?
THEY PLAY LOW NOTES?
James says YES.
Phil says SO, IS THAT BETTER WHEN
YOU HAVE A VAN LIKE THIS?
James says WITH A CAR AUDIO VAN LIKE THIS,
YOU WANT TO PLAY LOW NOTES.
LIKE YOUR HOUSE STEREOS
AND THAT WILL PLAY ANYTHING
FROM 120 TO 200 HERTZ.
I'M PLAYING 20 HERTZ
TO ABOUT 35 MAX
FOR YOU GUYS TODAY.
Phil says SO, THAT'S LIKE A SORT OF
RUMBLE OF THUNDER AND...
James says YES, VERY LOW.
(MAKING SHAKING SOUND)...
A caption reads "Listen closely, can you hear it?"
Phil says WHERE YOU REALLY FEEL IT.
IT'S LIKE A TRAIN
GOING PAST ALMOST.
James says YES.
Mikaela says OH, THAT'S COOL.
Phil says SO, WE GET OUR HEARING
PROTECTION ON
AND WE TRY IT OUT.
I KNOW WHAT YOU'RE THINKING.
PHIL, WHAT'S THE POINT
OF HAVING LOUD MUSIC
IF YOU CAN'T REALLY HEAR IT?
BECAUSE WE'VE GONE FROM
LISTENING TO MUSIC
TO FEELING IT.
They put on earmuffs.
(RUMBLING)
(LAUGHING)
Phil says THE SOUNDWAVES ARE SO STRONG
THAT THEY HAVE BECOME
A PHYSICAL PRESENCE.
MIKAELA'S HAIR FLIES AROUND,
BECAUSE THE AIR
FROM THE SPEAKERS
IS CREATING SHOCKWAVES.
THE SOUNDWAVES ARE SO POWERFUL,
THEY MOVE THE
AIR BACK AND FORTH
WHICH MAKES MIKAELA'S HAIR
DANCE ALL OVER THE PLACE,
AND MY HAIR NOT SO MUCH.
(SCREAMING)
(LAUGHING)
(LOW RUMBLING)
(WHOOPING)
(LOW RUMBLING)
Phil says SCIENCE!
(RUMBLING)
(LOW RUMBLING)
Phil says I'M TOTALLY JEALOUS
OF YOUR LONG HAIR.
Mikaela says YEAH, YOU NEED
TO GET LONGER HAIR.
Phil says OKAY, HOLD ON.
He puts on a wig and says OKAY.
WHOA!
SCIENCE MAX:
EXPERIMENTS AT LARGE!
They both say SUPER SOUND!
Phil says HIGH FIVES!
OKAY, READY TO DO AGAIN?
SO COOL!
Mikaela says YEAH! LET'S DO IT.
Phil says OKAY! THERE WE GO!
(LOW RUMBLING)
(RUMBLING)
They say AHH!
(LOW RUMBLING)
WHOO!
Now the end credits roll as gag reels from the show play.
Mikaela says IS IT AT THE BOTTOM?
Phil says I CAN'T...
I CAN'T REACH IT.
SO, THAT'S GREAT.
(SCREAMING)
The giant megaphone rolls off the table.
Phil says WAIT, WAIT...
ALMOST...
Phil drops his phone in a hole and says NO, I CAN'T.
At the parking lot, Phil says OKAY! I'VE GOT THE
HEARING PROTECTION ON!
Mikaela says PARDON?
Phil says YOU GOT YOUR
HEARING PROTECTION ON?
Phil says WHAT WAS THAT?
(CHUCKLING)
Phil rescues his phone and chuckles.
Mikaela says YAY!
Phil says HELLO?
OH, HI, MOM.
NO, I'M SHOOTING THE SHOW
Teacher James says RIGHT NOW. I CAN'T...
SCIENCE.
NOW, I CANNOT HELP BUT WONDER
HOW LOUD IT WAS IN THAT VAN.
DURING THE EPISODE
WE JUST WATCHED,
WE'VE SEEN SOUND VISUALIZED
IN A NUMBER OF DIFFERENT WAYS.
THERE'S BEEN THE DRUM WITH SALT
AND OTHER PARTICLES ON IT.
THERE'S BEEN THE
CORN STARCH MUD.
AND THEN, WE SAW THAT
LOUD ENOUGH SPEAKERS
AND LOW ENOUGH TONES WILL...
MOVE PEOPLE'S HAIR LIKE WIND.
WE ALSO HAD A LOOK AT
THE PHONAUTOGRAMS.
NOW, IF YOU THINK BACK TO THE
LIST THAT WE SAW...
THAT WE PUT TOGETHER
IN THE BEGINNING,
MAYBE YOU CAN SEE
THAT THERE'S ANOTHER WAY
THAT WE CAN VISUALIZE SOUND.
NOW, FOR THIS NEXT PART,
MAKE SURE THAT YOU
HAVE THE PERMISSION
OF THE BIG PEOPLE YOU LIVE
WITH BEFORE YOU START
AND DO BE CAREFUL ABOUT
DOING ANY OF THIS
BECAUSE WE'RE GOING TO ASK YOU
TO CUT SOME CANS AND ALL.
IF YOU CAN GET A RECYCLED CAN
AND THEN TAKE BOTH ENDS OFF
OF IT-- AGAIN, BE CAREFUL.
SOME OF THIS IS SHARP.
YOU MAY EVEN WANT TO PUT SOME
TAPE OVER ONE OF THESE ENDS.
AND THEN, FIND A BALLOON,
AND CUT THE END OFF OF IT
WHERE YOU WOULD NORMALLY
BLOW AIR INTO IT.
AGAIN, BE CAREFUL.
AND THEN, STRETCH IT OVER,
SO MAKE KIND OF
ANOTHER TINY DRUM.
AND I HAPPEN TO HAVE
A SMALL MIRROR
THAT I THEN ATTACHED
TO THIS TAPE.
YOU COULD ALSO USE A DIME,
IF YOU'VE GOT, LIKE,
A SHINY STICKER THAT,
YOU KNOW, LOOKS REALLY CLEAR,
A NUMBER OF THINGS MIGHT WORK.
THEY MAY OR MAY NOT BE AS CLEAR.
AND IF YOU'VE GOT A CAT AROUND,
MAYBE YOU'VE GOT ONE
OF THESE LASER POINTERS THERE.
AND JUST MAKE SURE YOU BE
CAREFUL WITH THIS,
WE DON'T SHINE IT AROUND
ANYONE'S EYES AND THAT
'CAUSE IT CAN DAMAGE YOUR...
DAMAGE YOUR VISION.
SO, IN A MOMENT,
I'M GONNA SET THIS UP
AND I'M GONNA USE SOME TRIPODS
AND OTHER THINGS TO
KEEP IT VERY STILL,
SO YOU CAN SEE THAT THE MOVEMENT
WILL BE COMING FROM THE SOUND
AND NOT JUST ME HOLDING AND...
AND THIS BEING SHOOK AROUND.
IF WE PUT...
IF I SHINE THAT ON...
YOU CAN SEE THERE'S THE
REFLECTION BEHIND ME.
As he points the laser against the mirror, it reflects on the wall behind James.
He says IF WE START PUTTING SOME SOUNDS
THROUGH THE OPEN
END OF THIS CAN,
WHAT'S GONNA HAPPEN ON THE IN...
WHAT IS GONNA HAPPEN TO THE
REFLECTED DOT OVER THERE?
REMEMBER BACK TO
THE WAY THE CRYSTALS,
THEY WOULD JUMP AROUND WHEN IT
HEARD THE SOUND THERE.
WHAT IS THAT GONNA
DO TO THE MIRROR
AND WHAT WILL SEE THAT...
WHAT WILL WE SEE THAT DO?
OKAY.
TRY TO THINK AND PREDICT TO
YOURSELF WHAT YOU'RE GONNA SEE
AND THEN WE'RE GOING TO...
WE'RE GOING TO SHOW YOU EXACTLY
WHAT'S GOING TO HAPPEN THERE.
NOW, MAYBE I CAN GET A NICE
'80S VIDEO TOASTER TRANSITION
INTO THIS NEXT PART.
SO, I'VE, UH...
RIGHT HERE, I'VE GOT THE
LASER POINTER ON A TRIPOD.
IT'S GOING INTO THE MIRROR
AND WE CAN SEE
ITS REFLECTION HERE.
NOW, I'M GONNA PLAY...
JUST SOME RHYTHMS HERE
AND LET'S WATCH WHAT HAPPENS
TO OUR LASER POINT.
(DRUM BEAT PLAYING)
The reflection starts moving around and changing shapes.
(DRUM BEAT PLAYING)
James says YEAH, SO, IT'S MOVING AROUND.
AS THE MIRROR MOVES
ON TOP OF THE BALLOON,
THE BALLOON IS SHOOK BY
THE SOUNDWAVES THERE,
AND WE CAN SEE, YOU KNOW,
SOME OF THE DIFFERENT BEATS
HAPPENING RIGHT IN FRONT OF US.
LET'S-- LET'S DO ANOTHER ONE.
(ROCK BEAT PLAYING)
(ROCK BEAT PLAYING)
James says SO, YOU MAY WANT TO WRITE
DOWN A QUESTION OR TWO NOW.
YOU ALSO MAY WANT TO CONNECT.
WHEN HAVE YOU SEEN A
PRESENTATION LIKE THIS,
WHERE THERE'S SOUND AND
THERE'S SOME KIND OF LASERS?
DOES IT WORK
SOMETHING LIKE THIS?
HERE'S SOMETHING
INTERESTING, THOUGH.
WE SEE A WHOLE LOT OF
DIFFERENT SQUIGGLES AND SOUNDS
BECAUSE WHEN YOU HEAR EVEN
JUST A DRUM BEAT LIKE THAT,
THERE'S THINGS HAPPENING ON
ALL KINDS OF FREQUENCIES -
THERE'S THE
HIGH-PITCHED CYMBALS,
THERE'S THOSE KIND OF
MEDIUM-PITCHED
SNARE DRUMS AND TOMS,
AND THEN YOU HAVE
THOSE LOW BASS DRUMS
THAT YOU JUST KIND OF FEEL MORE
THAN YOU ACTUALLY HEAR.
BUT WE CAN ALSO PLAY...
JUST-- JUST PLAY
A STRAIGHT TONE.
LET'S HEAR WHAT HAPPENS
WHEN I PUT IN JUST A...
JUST 200-- 200 HERTZ.
LET'S HEAR.
(MEDIUM TONE BLARING)
The reflection makes a circle.
(MEDIUM TONE BLARING)
James says DID YOU SEE THAT?
SO, WHEN WE WERE PLAYING
JUST THAT STRAIGHT TONE,
IT MADE JUST A CIRCLE.
AND THEN, WHEN SOME OTHER
INTERFERENCE CAME IN,
IT MADE KIND OF A FIGURE-EIGHT.
LET'S GO A LITTLE LOWER.
LET'S GO TO 150 HERTZ.
(LOW TONE BLARING)
(LOW TONE BLARING)
(LOW TONE BLARING)
(BEAT PLAYING)
SO, YEAH, ONCE AGAIN,
WE SAW THE SAME THING.
WHEN IT'S-- WHEN WE HAVE
THAT ONE CLEAN FREQUENCY,
IT MAKES THE...
IT MAKES OUR DEVICE
RESONATE IN SUCH A WAY
THAT IT BECOMES A LITTLE BIT
MORE-- MORE EVEN ALL OVER IT
AND WE START GETTING
THESE MORE PRECISE,
MORE MATHEMATICAL PATTERNS.
LET'S TRY-- LET'S GO DOWN
ONCE MORE TO 50 HERTZ
AND SEE WHAT WE CAN GET.
(LOW TONE BLARING)
The reflection stretches and makes circles.
(LOW TONE BLARING)
(LOW TONE BLARING)
James says YEAH. INTERESTING.
SO, IF YOU CAN MAKE A DEVICE,
SOMETHING LIKE THIS,
IF THE ADULTS IN YOUR HOUSE ARE
OKAY WITH YOU DOING THAT,
WHAT DO YOU THINK
SOME SONGS THAT YOU LIKE
ARE GOING TO LOOK LIKE?
NOW...
WE WERE TALKING ABOUT
USING HERTZ TO DESCRIBE
SPECIFIC MEASUREMENTS
WITH SOUND,
BUT THIS ALSO BECOMES USEFUL
WHEN THINKING ABOUT THINGS
THAT-- THINGS THAT WE CAN HEAR.
SO, AS HUMAN BEINGS,
WE CAN HEAR ABOUT...
UPWARDS TO 20 KILOHERTZ.
WE CAN HEAR THINGS UP
TO 20 HERTZ
AND AS HIGH AS 20 KILOHERTZ.
AND KILOHERTZ IS A FANCY WAY OF
SAYING 20,000 HERTZ.
THINK OF THIS LIKE KILOMETRES.
WE HAVE...
WHEREAS...
1000 METRES IS THE
SAME AS A KILOMETRE,
1000 HERTZ IS THE SAME
AS A KILOHERTZ.
SO, WHEN WE START TALKING
LARGER NUMBERS OF HERTZ,
IT JUST BECOMES
EASIER TO SAY THAT.
SO, HUMANS CAN HEAR UPWARDS OF...
UPWARDS OF 20,000, BUT THAT'S
NOT THE SAME FOR EVERYONE
BECAUSE MOST PEOPLE,
AS THEY GET OLDER,
THEY TEND TO LOSE A BIT OF
THAT HIGH END HEARING.
YOU CAN PROBABLY HEAR
SOUNDS AROUND 17, 18,
19, OR 20 KILOHERTZ THAT THE
ADULTS AROUND YOU CAN'T.
AND-- WELL, AND THEN
THERE'S SOME ANIMALS, LIKE...
OH, LIKE ZOEY HERE.
ZOEY. COME HERE, ZOEY.
He hugs his little black dog and says SO, ZOEY CAN HEAR SOUNDS
UP TO 45 KILOHERTZ.
SO, IF YOU'VE GOT,
LIKE, A DOG OR CAT
THAT MIGHT SEEM TO ACT LIKE
THEY'RE HEARING THINGS
WHEN YOU CAN'T HEAR ANYTHING,
IT MIGHT BE THAT THEY'RE
ACTUALLY LISTENING TO SOMETHING
OR HEARING SOME NOISE FAR OFF.
OKAY. DO YOU HAVE ANY QUESTIONS?
THIS'D BE A GOOD TIME
TO WRITE THEM DOWN.
(CHIME SOUNDING)
NOW, ON THE OTHER HAND,
WE SAW THAT, IN
SCIENCE MAX,
THAT LOWER FREQUENCIES,
LOWER HERTZ SOUNDS
ARE MORE FELT THAN LISTENED TO.
AND THINK ABOUT SOME
MUSIC YOU'VE HEARD.
WHAT ARE THE INSTRUMENTS YOU
HEAR THAT ARE LOW
AND THAT YOU FEEL
MORE THAN YOU HEAR?
PEOPLE WHO GET INVOLVED
WITH MUSIC PRODUCTION
AND MAKING MUSIC HAVE
TO BE AWARE OF THIS
AND THERE'S ALL
KINDS OF JOBS IN SOUND.
YOU MAY BE INTERESTING IN
SEEING MORE OF THE CAREERS
THAT YOU CAN TAKE PART IN
SOUND ENGINEERING
WITH THIS EPISODE OF
WHEN I GROW UP
AND A LOOK AT SOUND ENGINEERS.
OKAY, READY, ZOEY?
Mikaela pops up against a colourful animated background. She's around 13, with mid-length curly brown hair, and wears a blue sweater.
[WHOOSH]
She says MY NAME'S MIKAELA, AND SINCE
I CAN REMEMBER,
I'VE DREAMT ABOUT WHAT I'LL BE
WHEN I GROW UP!
THERE ARE SO MANY COOL JOBS,
SO I DECIDED TO TRY THEM ALL.
In animation, gear from different jobs appears on her: an astronaut's helmet, a construction worker's vest and helmet, a chef's hat and apron, and a police officer's hat and badge.
She says I BUILT AN AWESOME STUDIO IN
MY GARAGE,
SO I CAN MAKE AND SHARE VIDEOS
ABOUT MY JOURNEY.
She pops up in her garage. The place has a multi-coloured tile floor, hangers with different uniforms, a bike, a desk, and a colourful back wall with a graffiti that reads "When I grow up!"
She says IT'S ALL ABOUT DISCOVERING
WHAT I'LL BE
WHEN I GROW UP!
The name of the show appears in purple surrounded by colourful silhouettes of different animals and shapes. It reads "When I grow up."
A film countdown clocks appears.
In her studio, Mikaela says OH, HEY, EVERYONE.
I'M HARD AT WORK
EDITING A NEW VIDEO.
RIGHT NOW,
I'M FOCUSING ON THE SOUNDS.
THAT'S RIGHT - SOUND.
DID YOU KNOW THAT'S
A HUGE PART OF EDITING?
FOR EXAMPLE,
WHAT IF THE SOUND DOESN'T
MATCH UP WITH THE PICTURE?
DOESN'T MATCH UP
WITH THE PICTURE!
DOESN'T MATCH UP
WITH THE PICTURE!
OR A SOUND EFFECT THAT,
WELL, DOESN'T SOUND RIGHT.
As he drops a pen, a glass breaking sound is heard.
As he rings a bell, a dog barking sound is heard.
(GLASS BREAKING)
(BOING SOUND)
(DOG BARKING)
Mikaela says THERE'S A JOB THAT FOCUSES
COMPLETELY ON EDITING SOUND.
IT'S CALLED A SOUND EDITOR.
I'M GONNA CHECK OUT THE JOB,
SO MY AUDIO DOESN'T
SOUND LIKE THIS...
(ROOSTER CROWING)...WHEN I GROW UP.
Now in a different building, Mikaela says THIS IS WHERE SOUND EDITORS
WORK ON TV AND MOVIES
TO MAKE EVERYTHING
SOUND AWESOME!
IT'S SO COOL BECAUSE THERE'S
SO MANY COMPUTERS...
(VOICE ECHOING:)...AND VIDEOS, AND-- WAIT.
(NORMAL AUDIO:)
CAN YOU GUYS HEAR ME?
I THINK I KNOW WHAT HAPPENED.
GOOD THING WE'RE AT THE RIGHT
PLACE TO SEE HOW IT'S DONE.
COME ON!
As she walks inside, she says WOW! THIS PLACE IS MUCH
BIGGER THAN MY STUDIO.
Claire says HEY, MIKAELA.
Mikaela says OH, HI, CLAIRE.
CLAIRE'S A SOUND EDITOR HERE.
CLAIRE, WHAT'S YOUR FAVOURITE
PART ABOUT BEING A SOUND EDITOR?
Claire is in her thirties, with long straight red hair and wears jeans and a black sweater.
She says MY FAVOURITE IS HAVING FUN
AND MAKING IT WORK.
Mikaela says COOL. LET'S GO.
BUT FIRST, SHOULD OUR
FOOTSTEPS BE NORMAL OR SILLY?
UMM...
Claire says SILLY.
Mikaela says AGREED.
(HORN HONKING)
Mikaela says ONE, TWO, ONE...
(HORN HONKING)
Claire says OKAY, MIKAELA,
IF WE'RE GONNA DO SOME SOUND
EDITING, WE'RE NEED A VIDEO.
DID YOU BRING ONE?
Mikaela says YEP. I FILMED ONE SPECIAL
JUST FOR TODAY.
LET'S WATCH IT!
Mikaela says I CAN'T WAIT.
(BREATHING IN AND OUT)
In the video, Mikaela takes a walk outside.
A skater almost bumps into her and says WHOA! SORRY, DUDE!
OOPS.
She crawls through a crawl tube and shrugs.
The video ends.
Mikaela says STUNNING, JUST STUNNING!
WHAT DID YOU THINK, CLAIRE?
Claire says I THINK IT'S A GREAT VIDEO
TO HAVE SOME FUN
WITH SOUND EDITING.
WE CAN DO SOME SOUND EFFECTS.
WE CAN DO FOLEY
FOR THE HOPSCOTCH.
WE CAN WORK ON THE DIALOGUE
FOR THE SKATEBOARDER.
AND THEN,
WHEN YOU GO INTO THE TUBE,
WE CAN HAVE A LOT OF FUN.
Mikaela says SOUNDS GOOD!
(WACKY CARTOON
SOUND EFFECTS SOUNDING)
(MUFFLED MUSIC PLAYING)
Back in her studio, Mikaela says OH, HI, THERE.
SPEAKING OF SOUND,
I WAS JUST
TESTING OUT SOME MUSIC
I'M GONNA USE IN
ONE OF MY VIDEOS.
ANYWAY, WHY DON'T YOU CHECK OUT
HOW CLAIRE BECAME
A SOUND EDITOR.
(MUFFLED MUSIC PLAYING)
In animation, a comic book cover appears with the title "When they were growing up! By Mikaela!"
[PAGE FLIP]
The pages of a comic book flip.
A frame shows a little girl playing the piano.
Mikaela says WHEN CLAIRE WAS A KID,
SHE LOVED PLAYING MUSIC,
SO SOUND WAS VERY
IMPORTANT TO HER.
IN HIGH SCHOOL,
SHE STARTED MAKING SHORT FILMS
ABOUT HER EVERYDAY LIFE.
Another frame shows little Claire filming a butterfly.
Mikaela says CLAIRE LOVED WORKING
ON THE SOUNDS
THAT WENT INTO THE FILMS.
SHE WAS AMAZED
AT HOW MUCH A SCENE
COULD CHANGE JUST WITH SOUND!
(HORSE HOOVES POUNDING)
Another frame shows Claire watching a western movie.
Mikaela says AT FILM SCHOOL,
CLAIRE LEARNED THAT
THERE WAS A PART OF FILMMAKING
FOCUSED COMPLETELY ON SOUND.
Claire says WOO-HOO!
SHE ENJOYED IT SO MUCH,
FROM THAT POINT ON,
SHE KNEW SHE WANTED
TO BE A SOUND EDITOR.
(TRUMPET SOUNDING)
Mikaela says NOW THAT YOU'VE
LEARNED ABOUT CLAIRE
LET'S GET BACK TO THE SHOW
(RIM SHOT SOUNDING)
DING
Claire says ALL RIGHT, MIKAELA,
WELL, THIS IS WHERE WE'RE
GOING TO BE RECORDING FOLEY
AND ANDREA'S GONNA
RECORD IT FOR US.
Mikaela says HI, ANDREA!
Andrea says HI, MIKAELA.
Andrea is in her thirties, with long straight brown hair and wears a gray cardigan sweater and a black scarf.
Claire says NOW, THE AUDIO FROM WHEN
YOU WERE PLAYING HOPSCOTCH
DIDN'T QUITE WORK,
SO WE'RE GONNA RECREATE IT
HERE IN THE STUDIO.
Mikaela says AWESOME!
Claire says YOU GOT IT, THAT'S YOUR
HOPSCOTCH COURSE.
NOW, ANDREA'S
GONNA ROLL THE VIDEO
AND YOU'RE GOING TO DO YOUR
STEPS IN REAL TIME HERE
AND MATCH WHAT
YOU SEE IN THE VIDEO.
Mikaela says GOT IT.
Claire says I'M GONNA GET OUT OF YOUR WAY.
Mikaela says ROLL IT, ANDREA!
(THUDDING)
As she sees herself in the video playing hopscotch, she stomps her feet on the platform.
(THUDDING)
She says WHOO!
Claire says THAT WAS PRETTY GOOD!
I THINK WE GOT IT.
Mikaela says WAIT. CAN I JUST DO ONE MORE?
Claire says SURE.
Mikaela says ROLL IT AGAIN, ANDREA!
(THUDDING)
(THUDDING)
(THUDDING)
Mikaela says DID WE GET THAT ONE, ANDREA?
Andrea gives her the thumbs up.
Mikaela says NICE.
NOW THAT WE'VE DONE FOLEY,
CLAIRE'S GONNA SHOW ME
HOW TO DO SOUND EFFECTS
TO MAKE A VIDEO SEEM MORE FUN.
HOPEFULLY, IT'S A SNAP!
She snaps her fingers.
(SQUEAKY DOOR OPENING SOUND)
Mikaela says I MEAN, A SNAP.
(SNEEZING SOUND EFFECT)
I MEAN, A SNAP.
(SPLASHING)
I MEAN, A SNAP!
(MEOWING)
I MEAN, A SNAP!
(SNAPPING SOUND)
(SIGHING)
Claire says OKAY, MIKAELA,
SO THIS IS MY OFFICE.
Mikaela says COOL.
Claire says AND THIS IS WHERE
I DO MY SOUND EDITING.
WHAT SOUND EFFECTS
ARE WE DOING FIRST?
Claire says WELL, THE FIRST SCENE IN YOUR
VIDEO TAKES PLACE IN THE PARK,
WHERE YOU'RE JUST WALKING ALONG.
SO, WE WANT TO THINK
ABOUT ALL THE SOUNDS
THAT YOU COULD BE
HEARING IN THE BACKGROUND.
(SHEEP BLEATING)
(ANIMAL NOISES BLARING AT ONCE)
An animated Mikaela in the park says PHEW!
Mikaela says WHAT DID YOU HAVE IN MIND?
Claire says WELL, YOU COULD HEAR SOME BIRDS.
(BIRDS CHIRPING)
(BIRD CHIRPING)
Claire says WE COULD HEAR SOME TRAFFIC.
(ENGINES RUMBLING)
Claire says YOU COULD HEAR A POLICE SIREN.
(SIREN BLARING)
(SIREN BLARING)
Claire says AND IN A PARK, YOU COULD EVEN
HEAR PEOPLE PLAYING TENNIS,
LIKE THIS.
(WHACKING SOUNDS)
(WHACKING SOUNDS)
Mikaela says WHAT ABOUT THE SKATEBOARDER?
Claire says WELL, YOU COULD HAVE THE NATURAL
SOUND OF A SKATEBOARD GOING BY.
(SKATEBOARD RATTLING)
Claire says OR YOU COULD DO SOMETHING
A LITTLE DIFFERENT.
(SLIDE WHISTLE TRILLING)
Mikaela says THAT'S THE ONE.
AND WHAT ABOUT WHEN
I WENT THROUGH THE TUBE?
I WAS THINKING
SOMETHING... CRAZY!
Claire says OH.
WELL, HOW ABOUT THIS?
(CREAKING,
VOICE CACKLING)
(GIGGLING)
(CAT YOWLING)
Mikaela says THAT'S DEFINITELY CRAZY.
GUYS, THIS IS SO COOL.
CLAIRE'S ABOUT TO
SHOW ME HOW TO RECORD ADR.
THAT STANDS FOR
AUTOMATED DIALOGUE REPLACEMENT.
IT MEANS THAT YOU CAN RECORD
YOUR VOICE TO REPLACE AUDIO
THAT DIDN'T WORK OR MAKE
YOUR VOICE SOUND DIFFERENT.
In a high-pitch voice, she says LIKE THIS.
In a low-pitch voice, she says OR LIKE THIS.
In a scary, low-pitch voice, she says OR LIKE THIS.
Back in Claire's office, Mikaela says HOW DOES THIS WORK, CLAIRE?
Claire says SO, IN VIDEOS, IT'S REALLY
IMPORTANT TO UNDERSTAND
WHAT PEOPLE ARE SAYING.
SO, I THINK THERE
ARE A FEW PLACES
WHERE IT WOULD BE A GOOD IDEA
TO REPLACE IT WITH ADR.
WHEN YOU FIRST WALK IN,
YOU TAKE A BIG BREATH.
AND THEN, LATER, WHEN THE
SKATEBOARDER ROLLS BY,
THE SKATEBOARD WAS REALLY LOUD,
SO WE COULDN'T REALLY
HEAR WHAT HE SAID.
DO YOU WANNA REDO HIS VOICE?
Mikaela says TOTALLY, DUDE.
Claire says AND THEN,
WHEN YOU GO IN THE TUBE,
YOU CAN DO WHATEVER YOU WANT.
HERE'S YOU MICROPHONE,
SO WHENEVER
YOU'RE READY TO ROLL.
She puts on her headphones and says AND ACTION!
(BREATHING IN AND OUT)
In the skater's voice, she says WHOA! SORRY, DUDE!
Claire says THAT WAS PRETTY GOOD, BUT LET'S
TRY IT A LITTLE BUT FASTER.
Mikaela says OKAY.
WHOA! SORRY, DUDE!
WHAT'D YA THINK?
Claire says THAT WAS EXCELLENT.
As she sees herself crawl inside the tube, she says EXCUSE ME.
PARDON ME.
COMING THROUGH.
OH. OH. SORRY.
SORRY! UM, JUST GOING...
DID WE GET IT, CLAIRE?
Claire nods and gives her the thumbs up.
Mikaela says AWESOME!
SO, WHERE ARE WE AT, CLAIRE?
Claire says EVERYTHING'S READY TO GO.
IT'S TIME TO FINISH YOUR VIDEO.
Mikaela says LET'S DO IT!
Claire says HOW DO YOU FEEL
ABOUT THIS SOUND?
(DOG BARKING)
Mikaela says GOOD.
Claire says ALL RIGHT.
Mikaela says WHY DON'T WE MOVE
THAT OVER THERE?
Claire says YEAH!
SHOULD WE BRING THIS UP A BIT?
(COW LOWING)
(ROOSTER CROWING,
DOG BARKING)
(CAT YOWLING)
Mikaela says I HAVE AN IDEA!
MOVE THAT OVER HERE.
(CAT YOWLING,
ROOSTER CROWING)
Mikaela says CLAIRE, I THINK IT'S READY!
(DRUM ROLL SOUNDING)
In animation, Mikaela takes the film to the screening room.
Claire says ALL RIGHT, THE VIDEO'S DONE.
Mikaela says AND NOW IT'S TIME
FOR MY FAVOURITE PART -
THE FINAL SCREENING.
BUT THERE'S ONE THING MISSING.
(POPCORN POPPING)
(FANFARE SOUNDING)
As a bucket of popcorn pops up in her hands, Mikaela says AHH. POPCORN.
ROLL IT, PLEASE!
Now the video rolls with all the sound effects.
Mikaela says WANT SOME POPCORN?
(BIRDS CHIRPING)
(CAR HORN HONKING)
(DOG BARKING)
(SIREN BLARING)
(FEET THUDDING)
(SKATEBOARD RATTLING)
(SLIDE WHISTLE TRILLING)
The skater says WHOA! SORRY, DUDE!
(CAR HORN HONKING)
(SIREN SOUNDING)
Mikaela says EXCUSE ME. PARDON ME.
COMING THROUGH.
OH. OH, SORRY!
(CAT YOWLING)
(LAUGHING)
The video ends.
Claire says BRAVA!
Mikaela says BRAVA!
Back in her studio, Mikaela says WASN'T THAT GREAT?
I LEARNED SO MUCH, AND NOW,
I'M PRETTY SURE
I WANNA BE A SOUND EDITOR...
(WHISPERING:) ...FOR NOW.
YOU GET TO WORK WITH
LOTS OF CREATIVE PEOPLE
TO FIGURE OUT HOW TO
MAKE VIDEOS SOUND AWESOME.
AND WHEN RECORDING GOES WRONG,
YOU GET TO SAVE THE DAY.
NOW I KNOW MY VIDEOS
WILL SOUND PERFECT.
FOR EXAMPLE...
As he drops the pen again, an explosion sound is heard.
(EXPLOSION BOOMING)
Mikaela says WELL, ALMOST PERFECT.
SEE YOU NEXT TIME ON...
In a goofy cartoon voice, Mikaela says WHEN I GROW UP!
(MUFFLED MUSIC PLAYING)
The end credits roll.
Teacher James says SO, TODAY, WE'VE LOOKED AT
WHAT KIND OF CAREER
YOU MIGHT BE ABLE TO
CONSIDER GOING WITH SOUND.
IF YOU THINK ABOUT A LOT OF THE
THINGS YOU'VE WATCHED
AND LISTENED TO AND LIKED,
SOUND IS OFTEN
HALF THE EXPERIENCE
IN THINGS LIKE MOVIES,
TELEVISION, VIDEOS,
AND THERE'S A
WHOLE LOT OF HARD WORK
THAT DOESN'T GET NOTICED.
WE ALSO LEARNED THAT PITCH AND
SOUND IS MEASURED IN HERTZ
AND THAT CAN DESCRIBE WHAT OTHER
PEOPLE AND ANIMALS HEAR.
WE'VE LOOKED AT SOME WAYS
THAT YOU CAN USE SOUND
AND LOOK AT IT AND VIEW IT,
JUST USING SOME THINGS AT HOME.
BUT MOST IMPORTANTLY,
YOU'VE, HOPEFULLY,
GOT A NUMBER OF GOOD QUESTIONS
THAT YOU'RE CURIOUS ABOUT
AND WANT TO ANSWER.
GOOD SCIENCE ISN'T ABOUT
TRICKS AND SPECTACLE.
ALTHOUGH, TRICKS AND
SPECTACLE IS FUN.
BUT SCIENCE IS OBSERVABLE
AND REPEATABLE FACT
AND THAT'S FACT THAT'S UNCOVERED
BY CURIOUS PEOPLE LIKE YOU,
WHO ASK THE RIGHT QUESTIONS
AND FIND THE RIGHT ANSWERS.
THERE'S A LOT
GOING ON AT THIS MOMENT
THAT CAN BE PRETTY CONFUSING.
BUT IF YOU ASK
THE RIGHT QUESTIONS
AND BE PATIENT WHEN YOU DON'T
HAVE ALL THE ANSWERS RIGHT AWAY,
IN TIME, THINGS WILL START
TO MAKE A BIT MORE SENSE.
SO, STAY SAFE, BE WELL.
I AM SORRY WE HAVE TO GO NOW,
BUT YOU DON'T HAVE
TO STOP LEARNING.
Music plays as the end credits roll.
