Explain what a breaker box does in a house.
It protects each room by regulating how much electical current is sent to each room. It can shut off an outlet, a room, multiple rooms, or even the whole house if the electrical current is too great.
300
Which type of magnet is more powerful? An electromaget or a permanent magnet? and why?
What is an electromagnet? An electromagnet is controlled by electricity, you can make the electical current stronger or weaker depending on what you are using the magnet for.

Is a rubber tire an insulator or conductor?
What is a conductor?

What is the difference between a series circuit and a parallel circuit?
In a parallel circuit, the parts are connected so that current passes along more than one pathway. In a series circuit, the parts are connected so that the current goes through one pathway.

In a string of holiday lights, all of the lights work if one bulb is broken or removed. Use what you know about circuits to explain this.
The string must be a parallel circuit. In a parallel circuit there are two pathways for the electic current to take, this will skip over the missing socket.
