  1. Model on pg. 58LWhat do these 9 experiments have in common? https://www.youtube.com/watch?v=ViZNgU-Yt-Y

  2. Static electricity

  3. 58R (Top Half) Shirt/Balloon(s) Exploration https://phet.colorado.edu/sims/html/balloons-and-static-electricity/latest/balloons-and-static-electricity_en.html • Google “Phet Balloons Simulation” • Explore the Phet Simulation by trying to create motion between the + and the -

  4. 58R (Top Half) Shirt/Balloon(s) Exploration https://phet.colorado.edu/sims/html/balloons-and-static-electricity/latest/balloons-and-static-electricity_en.html • Google “Phet Balloons Simulation” • Explore the Phet Simulation by trying to create motion between the + and the -

  5. 59l Triboelectric (or electrostatic) Stations https://docs.google.com/document/d/1WdyyX19S-5NROhw_rTl8obxZWo9lnPqtyZ9CQxeUwKg/edit?usp=sharing At each station you will be rubbing the balloon against the materials then trying to pick up the paper punches. Wood, paper, human hair, hands, glass, styrofoam, cloth, polyester, fur, plastic wrap, aluminum.

  6. 59L Triboelectric (or electrostatic) https://docs.google.com/document/d/1WdyyX19S-5NROhw_rTl8obxZWo9lnPqtyZ9CQxeUwKg/edit?usp=sharing Tells us which materials have a greater tendency to hold on to their electrons and which have a greater tendency to lose their electrons.

  7. John Travoltage Middle of page 58R • Make John Travoltage have excess electrons. What do you see/what is the behavior of electrons? • What happens when John brings his finger towards the door? Why would the electrons move? • What happens when he has lots of electrons vs. fewer electrons? • From where is he getting the electrons? https://phet.colorado.edu/sims/html/john-travoltage/latest/john-travoltage_en.html

  8. 58R (Bottom Third of Page) John Travoltage • Compare the two simulations. What is the sweater balloon simulation trying to show you? • What is John Travoltage trying to show you? • What do you notice about the motion of the protons and electrons? • How do the static electricity stations we did last class connect to the two simulations we played with on Phet?

  9. Triboelectric Series page 59L/R + - Positive +- gives up negative electrons Rabbit Fur (+++) Hands Glass Human Hair Wool Silk (+) Aluminum Paper Cotton (neutral) Wood (-) Styrofoam Plastic Wrap Negative - gains electrons easily

  10. Triboelectric Series pg 59L/R + - What happens when . . . Aluminum is rubbed against human hair? Fur is rubbed against styrofoam? Teflon is rubbed against styrofoam? Dry hands are rubbed against Teflon? Positive +- gives up negative electrons Rabbit Fur (+++) Hands Glass Human Hair Wool Silk (+) Aluminum Paper Cotton (neutral) Wood (-) Styrofoam Plastic Wrap Teflon Negative - gains electrons easily

  11. Electrostatic discharges What environmental conditions favor static shock? What can you do to reduce the chance of getting a static shock? Explain what is happening in these animations. They are different!

  12. Static Stations There are two stations that you will be exploring today. You will be getting into groups of 3

  13. What do you wonder/What do you notice? (60L and 60R)
