Learn how heat energy can be produced by mechanical and electrical machines.

Students work in teams to learn about solar panel design, simple circuits, and how solar energy is used to provide power to simple machines such as calculators.

During this lesson, students will construct a passive solar house from everyday items then explore how the sun's energy is used to heat and cool it.

Compared to incandescent lamps, fluorescent lamps last longer, require less energy and produce less heat, advantages resulting from the different way in which they generate light.
