1. Electric Circuit A continuous pathway that can carry an electric current: The lights in your home are on an electric circuit.

2. Electric Current A flow of electric charges: Electric current flows through a circuit.

3. Electric Charge A basic property of the tiny particles that make up matter; it can be positive or negative: Some particles of matter have electric charge.

4. Static Electricity The buildup of electric charges in one place: Static electricity might make your hair stand up.

5. Electric Field The area around electric charges in which electric forces can act: Strong static electric charges have large electric fields.

6. Series Circuit An electric circuit with only one path that current can follow: If one bulb in a series circuit goes out, the others also go out.

7. Magnetic Poles One of the two areas on a magnet where it exerts the strongest force: Every magnet has two magnetic poles.

8. Electromagnet A device made up of a current carrying wire coil around an iron core: You can make an electromagnet with a nail, some wire, and a battery.

9. Kinetic Energy The energy of motion: When you move, you have kinetic energy.

10. Electric Motor A device that converts electricity to motion: Some toys have electric motors.

11. Generator A device that converts other forms of energy into electricity: People use portable generators when the power is out.

12. Insulated To protect from electricity by covering with rubber or another material that does not carry current: The red, blue, and green plastic insulates these wires.

13. Parallel Circuit An electric circuit with two or more paths that current can follow: If one bulb in a parallel circuit goes out, the others stay on

14. Resistance The measure of how much a material opposes the flow of electric current: Most metals have low resistance.

15. Magnetic Field The space around a magnet in which magnetic forces can act: The metal filings show where the magnetic field is.
