Give an example of one type of energy that comes from the Sun.
Answers will vary. Does it explain light or heat?

Define stored energy and name one example.
Stored energy is fuel that is not being used and waiting to be released. Examples include: batteries, coal, fire, oil all used to make electricity.
300
Which is NOT an example of stored energy? Explain how you know: battery, gasoline, wire, light bulb, food
wire and light bulb. Energy is flows through the wire to get energy into light or heat. A light bulb can't produce light without electricity, so it does not store energy.
300
How can the stored energy in a battery be converted into light energy?
Put the batteries in or use wires to connect the battery to a light bulb.

500
watch the tone generator experiment. Explain what the source and how you know energy was transferred?
The battery turns the tone genertor on. The sound waves from the tone generator creates energy through the air. The energy in the air moves the rice. The rice's movement shows energy was transferred. Without the sound waves, the rice would not move.
