Leo's Fishheads

Hot Water

Ready, set, science! A rainy day can't stop Leo and the FishHeads with their mission to help the Department of Fisheries and Oceans conduct a super cool - or, hot - science experiment. Christian is helping to net the Eastern Sand Darter, the perfect fish to gauge the temperature of the water, which is vital information for the scientists tackling environmental changes. How hot can it go before the darter starts darting?
