• Biomass is the combustion of materials that originate from living things.
• Chemical is used to fuel automobiles and other vehicles.
• Electrical drives many small machines and keeps lights glowing.
• Geothermal taps steam from water heated underground (like geysers) and uses it to spin
turbines.
• Hydrogen power uses electricity to break down water into hydrogen gas. The amount of
energy released is less than the energy used to break it apart, so not currently feasible.
• Hydroelectricity generates electricity by harnessing the power of flowing water (a renewable
resource as long as there is rain). Refer to the associated activity Water Power for students to
observe and learn about water related methods of harvesting energy.
• Kinetic is the energy of motion. A spinning top, a falling object, and a rolling ball all have kinetic
energy. The motion, if resisted by a force, does work. Wind and water both have kinetic energy.
Refer to the associated activity Wind Power to give students an understanding of how wind
energy is harvested and used.
• Light energy is generated from light bulbs and computer screens, the sun.
• Nuclear fusion imitates the method the sun uses to produce energy. It involves the joining
together of the nuclei of hydrogen atoms.
• Nuclear fission is when energy is given off from splitting nuclei of uranium atoms.
• Potential energy is the energy stored by an object as a result of its position. For example, roller
coaster at the top of a hill.
• Sound energy is created, for example, when a door slams, it releases sound energy.
• Solar energy occurs from the sun (light). Refer to the associated activity Solar Power for
students to explore this energy form.
• Thermal energy (or heat) boils water, keeps us warm and drives engines.
• Tidal energy is when the energy from ocean tides is harnessed.
• Wave energy is when the energy from ocean waves is harnessed
