What does a fluorescent bulb use to produce light?
What is gas? The gas heats up when the electric current passes through it.

How does lightning happen? Why does it happen?
How --> The negative charges have accumulated enough in the cloud to get attracted by the positive charges on Earth's ground.
Why --> Water particles bump against each other in a cloud creating negative charge.

What has more power a battery or an outlet?
An outlet?
400
Name two electrical devices that change electricity into motion.
What is (anything with a motor) a fan, a vacuum cleaner, for example.
400
If a balloon has more positive charges than negative charges, it is considered to have what kind of charge?
What is positive charge?
500
Describe what happens when lightning strikes the ground. Where does the electricity flow - from what to what?
What is electricity flows from the clouds to Earth?
500
In a series circuit, if one bulb burns out - will the current flow in the circuit? Why or why not?
No. If any part of a series circuit is broken or removed, the circuit is open and will not flow.
