Whoa! I have two fish in my aquarium. Betty, my white goldfish always stays really close to the front wall as she swims towards her food. However, Stripe, my striped goldfish swims diagonally across the tank to the back top right to retrieve his sprinkle of food.
I wonder which fish swims a greater distance? How much longer a trip does Stripe take? What information do you need to find out?
Check out this blogpost write up of this activity by a math teacher and blogger, Martin Joyce.
Extension: Once you figure out which fish swims a greater distance think about how much faster that fish has to swim compared to the other fish in order to get to the food at the same time?
