1. Electricity is the flow of electrons.
2. The word that means "go around" is circuit.
3. Electrons and water are alike because both can flow and carry energy.
4. You don’t get shocked in a bumper car because the car is insulated and the electrical system is designed to keep current within the circuit, not through you.
5. Cold metal conducts electricity better than hot metal.
6. A material that allows electricity to flow is called a conductor.
7. A material that does not allow electricity to flow is called an insulator.
8. We measure the “pressure” of electric circuits in volts.
9. We use amperes (amps) to describe the amount of electrons flowing on a circuit.
10. The combination of voltage and amps is called power, measured in watts.
11. The South American Eel produces about 600 volts.
12. Turbines are located in dams that produce electricity from falling water.
13. Electricity that flows in 2 directions is called alternating current (AC).
14. Electricity that flows in 1 direction is called direct current (DC).
15. The cells that harness the sun’s energy for electricity are called photovoltaic cells or solar cells.
16. Birds can sit on a power line and not get electrocuted because they are not completing a circuit to the ground — no current flows through their bodies.
