T/F: An insulator does not conduct electricity.
What is true?
100
What happen if you have a closed circuit?
Electricity flows completely through and the device will turn on.
100
A material that allows electricity to pass through easily.
What is a conductor?
200
A constant flow of electrons through a conductor.
What is electric current?

Why does lightning occur?
When a a cloud and rain rub together.
200
Give an example of a good conductor of electricity.
What is steel, copper, water.
200
If a light is out in a series circuit, what happens to the rest of the lights?
None of them work.
200
A material that does not let electricity flow through easily.
What is an insulator?
300
The smallest particle of a substance.
What is an atom?
300
What causes static electricity?
When positive and negative charges are not balanced.
300
Give an example of a good insulator of electricity.
What is wood, rubber, glass.
300
If a light is out in a parallel circuit, what happens to the rest? Why?
The rest of the lights work because they each have their own loop to the source.
300
An electric circuit in which each device has its own loop.
What is a parallel circuit?
400
The buildup of electric charges on an object.
What is Static Electricity?
400
How is an electromagnet formed?
A coiled wire is wrapped around an iron core.
400
What would happen if the rubber coating on a wire was broken?
You would get shocked.
400
Explain the process of electron flow in a closed circuit. Include the 4 materials needed to make a circuit.
Electrons are let go from the source (battery,) flow through the copper wire, to the switch, through more wire, to the device, through wire, back to the source.
400
An electric circuit in which the devices are connected with a continuous loop.
What is a series circuit?
500
A particle that is around hte nucleus with a negative charge.
What is an electron?
500
Why does a compass work?
Because the Earth has magnetic poles so the needle is attracted to them.
500
Explain why an object conducts electricity. Use the words electrons, and resistance in your explanation.
Electrons are easily let go so they have a low resistance.
500
What type of circuits are used in a house? Why?
Parallel circuits, because if you had series circuits, if one light was out the rest of the lights in the house would be out.
