Electrical energy is created by the movement of electrons through a circuit. A circuit can be open or closed, with a closed circuit allowing electrons to flow freely and an open circuit preventing flow. Materials that allow or prevent electron flow are conductors and insulators respectively, with common examples like copper and plastic provided.

2. Electrical Energy
A from of energy created by the movement of electrons.
electrons

3. Electrical Circuit
The pathway through which electrical current flows

4. Closed Circuit
A circuit where there are no gaps and electrons can flow freely

5. Open Circuit
A circuit where there is a gap or opening that prevents electric
current from flowing freely or stops the flow

6. Insulator
A material that does NOT allow heat energy or electricity to pass
through it easily
plastic wood glass cotton ball
styrofoam rubber

7. Conductor
A material that allows heat energy or electricity to pass through it
easily
water aluminum foil
screw copperPaper clip

8. Current
The flow of electricity through a circuit

9. Switch
A device that open or closes an electric circuit to stop or start the
flow of electrons

10. Wires
A thin flexible metal strand, often wrapped in plastic

11. Cell
A container holding chemicals that produce electricity; battery
