This Efficiency of a Water Heating System activity also includes:
Tired of waiting for hot water? Groups of three determine the efficiency of an electric water-heating device. They calculate the amount of energy it takes to heat the water and the theoretical amount of energy required to heat the water. The class then compares the efficiency of each device and determines which method is the most efficient.
