  • 1. How did Benjamin Franklin feel when he discovered electricity? He was shocked!
  • 2. Father of Electricity Benjamin Franklin
  • 3. Curiousity led Franklin to investigate electricity!
  • 4. Key, Kite, Leyden Jar helped in discovery
  • 5. Franklin invented the lightning rod
  • 6. Lighning would strike the rod not the house. With Without
  • 7. Volta discovered first battery!
  • 8. Did you know?
  • 9. Electricity and magnets are related!
  • 10. Michael Faraday Produced electricity by placing a magnet through copper wire
  • 11. Electromagnet http://www.fossweb.com/modules3-6/MagnetismandElectricity/activities/electromagnet.html See how it works! He produced an electromagnet!
  • 12. These items use electromagnets. Can you think of more?
  • 13. Electricity : energy produced by moving electrons.
  • 14. Cause Electricity Moving electrons
  • 15. Edison and Westinghouse created the first power stations.
  • 16. Electrically charged particles flow from powerstations into homes. Electric Current
  • 17. Transformation Just as the caterpillar changes to a butterfly...
  • 18. Electricity is transformed into other forms of energy...
  • 19. Light Energy

  • 26. The amount of electricity an object uses. WATT http://www.engineeringinteract.org/resources/siliconspies/flash/concepts/electricity.htm Check it out:
  • 27. Static Electricity Build up of negative charges
  • 28. Lightning Negative static charges jump to positive charges
  • 29. Circuit Path that electric current flows
  • 30. Series Circuit One goes out, they all go out!
  • 31. Series Circuit http://www.engineeringinteract.org/resources/siliconspies/flash/concepts/simplecircuits.htm Great activity Check it out!
  • 32. Parallel Circuits Buildings and homes are wired this way.
  • 33. Parallel Circuits When one path is broken...
  • 34. The other paths work!!!
  • 35.
    • http://www.engineeringinteract.org/resources/siliconspies/flash/concepts/buildingcircuits.htm
    Build your own circuit!
  • 36. Conductors allow electricity to flow through it.
