100

This is the flow of electric charges that moves in an unbroken loop.

What is an electric current?

100
These are materials through which an electric current can pass.
What are conductors?
100
Early scientists most likely saw a discharge of electricity for the first time while observing this.
What is a lightning storm?
100

The particles in an atom carry a negative charge.

What are electrons?

100
In this type of circuit, electricity has only one path to follow.
What is a series circuit?
200

This is the pathway taken by an electric current.

What is a circuit?

200
These are materials through which an electric current CANNOT pass.
What are insulators?
200
These are three examples of non-renewable sources of energy.
What are coal, natural gas and gasoline?
200
This term means "to push away".
What is repel?
200
In this type of circuit, electricity has more than one path to follow.
What is a parallel circuit?
300
This type of circuit is a complete circuit where everything is connected and electricity can easily flow through it.
What is a closed circuit?
300

Give three examples of conductors. (Hint: think of the experiment we did in class!)

What are nails, paperclips, and aluminum foil? (Anything metal!)

300
These are three examples of renewable sources of energy.
What are solar, hydro, and geothermal energy?
300

If you take electrons away from your hair by using a balloon, your hair will have this type of charge.

What is a positive charge?

300
This person invented the light bulb.
Who is Thomas Edison?
400
This type of circuit is an incomplete circuit where there is some part that is not connected and electricity cannot flow through it.
What is an open circuit?
400
These are some examples of insulators.
What are plastic, wood, and rubber? (There are many other examples!)
400

This is the unit used to show how much "push" a battery has to move electrons through a circuit.

What is a volt?

400

This is the term to show that an object has an equal number of protons and electrons (no charge).

What is neutral?

400
These are the basic materials needed to make a complete circuit.
What are a power source (battery or outlet), wires, and a light bulb?
500
This is a device that is used to open and close a circuit easily without connecting and disconnecting the wires.
What is a switch?
500
This is the name of the crackle you hear and feel when you touch a doorknob after rubbing your feet across a carpet.
What is static electricity?
500

This is a material that cuts down the flow of current, but does not stop it.

What is a resistor?

500

This is when all the electrons suddenly move and a charged object becomes neutral again.

What is discharge?

500

This can happen when the path the electrons follow doesn't have enough resistance.

What is the wire can heat up (there can be a fire)?
