Energy Transformations KWLH Chart
Read: A windy afternoon
Amira is helping set up a small wind turbine at a coastal science centre. The wind makes the turbine blades spin. Inside the turbine, a generator changes some of the blades’ kinetic energy into electrical energy. Wires carry the electricity to a small lamp. The lamp changes electrical energy into light and also gives off some heat. Not all the energy ends up in the useful form we want: some spreads to the surroundings as sound and heat.
- Movement energy
- Light energy
- Sound energy
- Electrical energy
- Use the same turbine, measure its rotations for the same time, and change only the wind strength.
- Use a different turbine each time and guess which one spins fastest.
- Change the wind strength and the time measured at the same time.
- Watch the turbine once without recording anything.
