Students will model and measure energy transfers from light to heat.
Students will easily figure out how to get two energy transfers just by using the solar panel to run a light bulb or motor. It will be harder for them to figure out that heat given off by light bulbs and motors. To get four or five energy transfers will require a lot of thought by students. One possibility: batteries to light bulb to solar panel to motor or voltmeter.
Students should be aware that energy comes as light, heat, electricity, kinetic and chemical and that it can change from one form to another. They should receive instruction of the use of the voltmeter and solar panels if necessary. This is a good time to review circuits as well.
Scoring Guide:
