You will get to refine and expand your knowledge of energy conversions to include electrical, chemical, and thermal energy. Then design your own power plant while learning about renewable and nonrenewable energy resources.
After completing this tutorial, you will be able to complete the following:
Which energy source is needed for a flashlight to work?
~ For a flashlight to work, it needs batteries as a source of electrical energy.
How is electricity generated when the button of the flashlight is pressed?
~ When the button of the flashlight is pressed, the chemical energy of the batteries is converted into electrical energy.
How does this electricity cause the flashlight to give off light?
~ The electricity generated by the batteries heats up the filament of the lamp. When it is sufficiently heated, the filament glows.
Glowing, filament of the lamp radiates which type(s) of energy?
~ The glowing filament radiates both light and thermal energy.
