Can be any of the following: wood, plastic, glass, rubber, paper, cardboard, styrofoam, cloth
200
In a series circuit, what happens if one light bulb goes out?
All the light bulbs go out.
200
In a parallel circuit, what happens when one light bulb goes out?
All the other light bulbs stay on.
300
If you face the north pole of one magnet toward the south pole of another magnet, what will happen to the magnets?
They will attract and be pulled together.
300
How can the strength of an electromagnet be changed?
By adding more electricity through batteries or coils.
300
Name three types of metals that can be conductors.
Can be any of the following: steel, iron, gold, silver, copper, bronze, aluminum, brass, zinc, nickel, lead
300
Draw a simple circuit on the board.
Power source, connected to conductor, connected to light bulb, connected to another conductor, connected back to power source. (May have switch.)
300
What does a conductor do?
Allows electricity to flow through it.
400
If you face the north end of one magnet toward the north end of another magnet, what will happen to the magnets?

400
Draw a bar magnet with poles on the board.
A rectangle or horseshoe shape with a north and south pole.
400
How is static electricity created?
Too many positive or negative particles are present, and the item wants to be balanced, so it tries to get rid of the extra particles.
400
What are the four components of a circuit?
Power source Switch Item that needs electricity Conductor
400
What does an insulator do?

Can be any of the following: steel, iron, nickel, cobalt
500
Why does a compass always point to the north?
The earth is a giant magnet, and a compass can pick up on the earth's magnetic field.
500
What is the function of the power source in a circuit?
It provides electricity to the circuit.
500
What is the function of a switch in a circuit.
It opens and closes the circuit, which turns the electricity on and off.
500
What is an example of electricity created by nature?
