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
These are temporary magnets, NOT permanent magnets.
What are electromagnets?
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

These are examples of conductors.

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
This is the invisible force field around every magnet.
What is a magnetic field?
300
This is a material that cuts down the flow of current, but does not stop it.
What is a resistor?
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 measure the energy used by an appliance (like a microwave) in a certain amount of time.
What is a watt?
400
All magnets have these two types of poles.
What are north and south poles?
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
A battery makes a motor run by changing electrochemical energy into this type of energy.
What is mechanical energy?
500
To make an electromagnet, a conductor could be coiled around this.
What is an iron or steel nail?
500
This person invented the light bulb.
