100
Everything in the world is made up of what?
Atoms
100

Inside each atom (but not in the nucleus) is a smaller part called what?

Electrons

100

How does electricity move?

Electrons jump from atom to atom.

100
What are three things that are in an atom?
Protons, neutrons, and electrons.
100
What what kind of charge does a proton have?
A positive charge.
200
What kind of charge does an electron have?
A negative charge.
200

Define electric current?

The rate at which electric charge (typically electrons) flows past a specific point in a conductive material within a closed circuit. 

200
What two parts attract each other?
Positive and negative.
200

When would an atom have no electric charge?

When protons (+) equal number of electrons (-).

200
What is static electricity?
A charge that stays on an object.
300
What do unlike charges do?
Attract each other.
300
What do like charges do?
Repel each other.
300
What is an electric current?
The steady flow of electricity.
300

What is a circuit?

A current that moves along a wire or path in a single direction

300

What is a series circuit?

A circuit that has only one path for the current.

400

What is a benefit of parallel circuits?

Provides many pathways for electricity; if one path fails, others still will work (unlike series circuits)

400

What is an example of a conductor?

Several examples can be given such as metals, salt water, etc.

400

What is an example of an insulator?

Several examples can be given such as plastic, rubber, wool, etc.

400

Define "conductor"?

A material that current can pass through easily.

400

What is "voltage"?

Pressure or force from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop between two points

500
How do we get electricity?
When an electron moves to a different atom, it causes another electron to have to move. When electrons move quickly from one atom to another it makes electricity.
500

What is an insulator?

A material that current cannot pass through easily.

500

Lightning strikes occur when ____________ charges at the ground attract negative charges at the bottom of a storm cloud.

Lightning strikes occur when POSITIVE charges at the ground attract negative charges at the bottom of a storm cloud.

500

How does a battery generate electric current?

Batteries store chemical energy (in the form of chemical potential energy) within their internal components. When connected to a device, this stored chemical energy is converted into electrical energy through chemical reactions in the battery. 

500

Describe how static charging by contact occurs?

Two materials rub together and transfer electrons.
