A material that electric charges can flow through easily
What is a conductor?
100
Objects with unlike charges do this.
What is attract each other?
100
The point on a magnet where the force is the strongest.
What is the magnetic poles (North & South)?

You rub a balloon with a wool cloth and touch it to the wall. The balloon sticks. What do you know about the electric charges on the balloon and on the wall?
What is opposite charges attract? Rubbing the balloon gives it more negative charges, which means the wall must have more positive charges.

If there's a gap in a circuit, then we say the circuit is this.
What is open?
200
The build up of electric charges on an object.
What is static electricty?
200
Objects with like charges do this.
What is repel?

You walk across a carpet and then touch your cat. Both you and your cat feel a shock. Why does this happen?
What is an electric discharge is given off when you touch your cat. Negative charges have built up on you when you walk across the carpet.
