  1. 3rd Period Science Static Electricity

  2. Hair and Balloon Attraction • The balloon takes the loose electrons from your hair. Then the positive and negative charges attract.

  3. Salt and Balloons Attract • Salt is positive and with the balloon rubbed against the wool, and it has more electrons than protons, so it attracts the salt.

  4. Balloon and Wall Attraction • The balloons are charged negatively when rubbed against the wool. Since the wall is positive the balloon attracts to it.

  5. Balloon and Can Races • The cans are attracted to the balloon, since opposites attract. Ellie and Kassi raced down the hallway with this experiment.

  6. Lemon Battery Lab • We used one lemon to make a cell battery on the first day. • On day two, we used four lemons to create a series circuit to light a LED light.

  7. Van de Graaff Designer Hats

  8. Van de Graaff Generator • The Van de Graaff generator is a machine that transfers electrons from an internal belt to the dome, which produces static electricity.

  9. Van de Graaff Discharge • To discharge the generator after an experiment, we used the discharge wand. • This prevents unexpected shocks from the Van de Graaff by transferring the extra electrons to the ground.

  10. Van de Graaff Experiments • Tape and Tack • Designer Hat • Muscle Contraction • Fluorescent Light • Paper Towel • Chain Shock • Bubbles • Hair Lifting

  11. Vocabulary • Repulsion - Same charges in hair and the Van de Graaff jump apart from each other. • Attraction - Objects with opposite charges, like protons and electrons, come together.
