Comparing Light Bulbs

This Comparing Light Bulbs lesson plan also includes:

An average home produces twice as many emissions as an average car. Teach your class how to reduce energy consumption by replacing standard incandescent light bulbs with compact fluorescent light bulbs. Perform an experiment to compare the energy efficiency of each, measuring the energy wasted in the form of heat. Use this experiment to teach conservation during Earth Day, or include in a science unit on different forms of energy.
