  1. Electricity! By Denzel and Jessica

  2. Electricity • Atoms have protons, neutrons, and electrons. • Same number of protons and electrons, it is balanced and neutral • Sometimes electrons get knocked out of place – free electrons • If they go to where other electrons are missing, this creates a current of electricity!

  3. Static Electricity! • Charge that stays on an object • When something gives up or gains electrons • Does not move along a wire or other conductor

  4. Current Electricity! • Electric charges are called electric current. • Free electrons continuously move to spaces where electrons are missing.

  5. Examples • Light bulbs • Cars • Computers

  6. Conductors • A conductor is a material that current can pass through easily

  7. Examples • Metal • Paper clips • Silverware • Wires • Water

  8. Open-Closed Circuits • If a switch is opened electrons stay still. No electricity moves. • If a switch is closed electrons move and energy is released.

  9. Parallel-Series Circuits • The series move in a circle • The parallel circuit moves in a straight line • The parallel series moves in a straight line and in a circle

  10. Chemical • Chemical changes cause energy • Batteries • Glow sticks • Pop Rocks

  11. Mechanical • Generator • Robots • Trains • Windmill • Motorcycles

  12. Nonconductors • Do not allow electricity to pass through easily • Insulators • Rubber • Plastic • Glass

  13. Household Electricity • What are some types of household electricity? • Cords • Computers • TV • Microwave • Stove

  14. Safe Use Of Electricity • Don’t pull cords • Don’t put metal in an electrical appliance
