Efficiency equals money where homes are concerned. A comparative lesson asks learners to measure heat output of incandescent and compact fluorescent light bulbs. They follow their investigation with calculating the cost of using the two...

Careful, that light bulb is hot! Compare heat and light energy using a simple light bulb. The exercise addresses energy conservation and presents actual calculations to determine the most cost-effective light bulb.

How many humans does it take to power a light bulb? The 10th part of a 25-lesson Energy Systems and Solutions unit has learners conduct an experiment to calculate power. They then use the results to determine how many classmates they...

Students demonstrate simple circuits and find the differences between parallel and serial circuits.  In this electronic lesson plan students work in teams to test different designs using a low voltage light bulb. 

Compare heating and cooling rates of different land forms. A lab activity has groups collect data on the rate of heating and cooling of soil, grass, saltwater, fresh water, and sand. An analysis of the rates shows how the different land...
