Youngsters make a mental assessment of electricity-consuming appliances in their homes and then evaluate them for the amount of energy consumed. They learn how to use power meters and measure the electrical consumption of several devices. After calculating the cost of energy used, they analyze and discuss results. This is a useful lesson for introductory physical science classes.
