What a learner can do afterwards
- Design a device that converts one form of energy to another (e.g. electrical to light, kinetic to sound)
- Build, test, and identify what works well and what needs improvement
- Explain the energy conversion taking place in the device
The lesson
You already know energy travels from place to place and changes as it goes. Now it is your turn to make that change happen on purpose. An energy-converting device takes one kind of energy, like electrical energy, and turns it into another kind, like light or sound.
A hand-crank flashlight is a good example. Turning the crank gives kinetic energy from your hand. Inside, that motion changes into electrical energy, and the electrical energy changes into light in the bulb.
When you test your device, write down what happens. If it does not work the way you hoped, that is useful information, not a failure. Change one part, then test it again.
Pick two energy forms, build a device that changes one into the other, then test it and make it better.
