  • 1.
    • Static
    • electricity
  • 2. Current electricity – Current electricity can be used by people. when electrons flow through a circuit. There are two categories (types) of electricity:
  • 3. There are two categories (types) of electricity: Current electricity – Current electricity can be used by people. when electrons flow through a circuit.
  • 4. There are two categories (types) of electricity: Static electricity – when electrons build up on an insulator (rubber, clothing, non-metals) causing an imbalance. The “charge” of static electricity is sometimes discharged (balanced) by a spark. This type of electricity is not used much by people, but can be fun (and sometimes dangerous).

    • Everything is made of tiny particles called atoms.
  • 8.
    • Atoms have positively (+) charged protons in the middle

    • Atoms have positively (+) charged protons in the middle
    • and negatively charged electrons (-) orbiting quickly around them.
    _ + _ +
  • 10.
    • Protons always stay with their atom, but electrons sometimes move to different atoms.
    • Traveling electrons are what we know as electricity.
  • 11. When more negatively charged electrons are on an object it has a negative charge. If electrons have been taken away, the object will be have a positive charge because it is out of balance toward the positive protons.
  • 12. Your body is an object that can become unbalanced with a negatively charge when you shuffle your shoes on a carpet. The spark that jumps from your hand to the doorknob balances your static charge. You have to walk on the carpet some more to get another spark.
  • 13.
    • Two objects with static charges can attract or repel each other much like magnets.
    • If the charges are the same (both positive or both negative) the objects will repel just like magnets.
    • If the charges are different, they attract.
    • (Opposites attract)
    + + _ _
  • 14. Different charges attract Charges that are the same repel each other.
  • 15. The reason this hair looks so funny is because each hair has the same static charge. Each hair is repelling all the others.
