If the north poles of two magnets are close, they will:
What is Repel
200
What happens when you put opposite poles together?
What is They attract
300
You rub a plastic comb with wool.Why will the comb then attract small bits of paper?
a. The comb has a magnetic attraction.
b. The bits of paper have electric discharge.
c. The comb and paper both have a negative charge.
d. The comb has a negative charge.

300
Explain one way to change a circuit.
What is
.Adding more bulbs
.Add another battery
.Switch the wires around
300
An insulator is:
What is an insulator is a material through which an electric charge cannot easily flow.
300
How can you turn a magnet into an electromagnet?
What is by wrapping a wire around a nail.
300
Why do we need electricity?
What is to power our phones,houses,and to give us light.
400
What is it called when electrons move quickly from one object to another?
What is Electric Discharge
400
Explain how a bulb works.
What is The filament wire is very thin,so electrons have a hard time passing through. When electrons do pass through, the filament becomes hot and begins to glow.
400
Give three examples of insulators.
What is Most plastics,Glass,Cloth,Sand,Rubber,Wood,Dry air
400
What is the magnetic field?
What is the area where magnetism is the strongest.
400
I have two light bulbs
One of my bulbs is broken
but the other one still lights
What am I?
What is a parallel circuit
500
Explain what happens when you rub a balloon on your head and then stick it to the white board.
What is The balloon picks up electrons from your hair giving it a negative charge and then attracts to the positive charge of the whiteboard.
500
In which part of a circuit is electrical energy changed into other forms of energy?
a. The battery
b. The switch
c. The wire
d. The load (anything that uses current to work)
What is The load (anything that uses current to work)
500
Explain how you can test whether an object in an insulator or a conductor.
What is Build a circuit and see if the object light the bulb or not.
500
Name two advantages of electromagnets.
What is
1. They can be turned of and on.
2. They can be stronger or weaker by changing the strength of the battery or wire loops.
3.The direction of the fields can be changed(switch the poles )by switching the ends of the battery.
500
I have a battery and two wire
I also have a switch
but there is a break in the wires
What am I?
