Give 2 examples of power sources
What are wall outlets and batteries?
What are the two types of circuits we've learned about?
What are a series circuit and a parallel circuit?
What is the difference between kinetic energy and potential energy?
What is, potential energy is when objects are at rest and kinetic energy is when objects are moving?
How does alternating current differ from direct current?
What is, direct current always flows in the same direction; the direction of an alternating current switches back and forth?

What are light bulbs, TVs, computers, refrigerator, etc.
What happens if you disconnect a circuit from its positive terminal?
Does an object have more potential energy the higher up it is, or when it is on the ground?
What is, the higher up it is?

What are rubber, plastic and glass?
What is the main difference between a series circuit and a parallel circuit?
What is, there is only one pathway in a series circuit; there are multiple pathways in a parallel circuit?
What do wind and moving water have in common?
What is, they both have mechanical energy?
Why is static electricity not useful as a power source?
What is, because all energy is released at once in static electricity?
The part of a battery where the electrons flow out of
What is the negative terminal?
List 3 examples of conductors
What are gold, silver and copper?
What type of current is a circuit connected to a battery?
What is direct current?
What is the sun?
What is one possible reason why it’s a good idea to conserve electricity?
