100

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

What is an electric current? (electricity is also an acceptable answer)

100

These are materials through which an electric current can flow.

What are conductors?

100

True or false: Electrical energy can be transformed into many other types of energy

What is true?

100
These are temporary magnets, NOT permanent magnets.
What are electromagnets?
100

This is when negatively charged particles are transferred between two objects

What is static electricity?

200
This is the pathway taken by an electric current.
What is a circuit?
200

These are materials through which an electric current CANNOT flow.

What are insulators?

200
A battery makes a motor run by changing electrochemical energy into this type of energy.
What is mechanical energy?
200
This term means "to push away".
What is repel?
200

This is a dangerous electrical situation where a circuit is missing a device that uses up some of the electrical energy.

What is a short 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. (Hint: think of the experiment we did in class!)
What are nails, paperclips, and aluminum foil? (Anything metal!)
300

This is the energy transformation that occurs when you use a microwave.

What is electrical energy -> thermal energy?

300
This is the invisible force field around every magnet.
What is a magnetic field?
300

This is the reason it is not safe to use electrical devices in/near water.

What is the conductive nature of water?

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

These are the two sources of electricity that we commonly use.

What are batteries and power from a wall outlet (originating from a power plant)?

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 simple 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

Early scientists most likely saw a discharge of electricity for the first time while observing this.

What is a lightning storm?

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.
Who is Thomas Edison?
