7. Electricity

8. Electricity • a form of energy that is produced when electrons move from one place to another place Electron Electricity -> Atom

9. Electric Current • the constant flow of electrons

10. Conductor • materials that allow electricity to move through them easily • Examples: foil, metal, water, most liquids, humans (because we are made mostly of water)

11. Insulator • Materials that resist the flow of electricity • Examples: rubber, plastic, cardboard Metal wires Plastic insulator Another plastic insulator

12. Electric Circuit • a pathway that electrons flow through (a circle)

13. Open Circuit • there is no flow of electrical current. The flow is interrupted. • Examples: light bulb is out, light switch is off, battery is dead

14. Closed circuit • Electricity flows without interruption • Examples: Light switch is on, battery in the game
