Students ask if convection currents are strong enough to move heavy objects. they use a fish tank and a toy boat that floats. then they place the boat in the tank and watch it for 10 minutes. it doesn’t move. next they put a hot plate under one side of the fish tank and turn it on. they watch for a half hour, and at the end of that time, the boat has moved across the aquarium away from the heat. what is a flaw in the experimental design of this experiment? question 14 options: the toy boat should have enough weight to sink. the hot plate should have been used in the first test. the fish tank should have been filled with different liquids. the amount of time should have been the same for both tests.
