5. 59l Triboelectric (or electrostatic) Stations
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)
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?

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

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

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)

15. 59R Static Electricity Research Notes: 59R
What is Static electricity?
What affects the strength of static electricity?
What affects the direction of the electric force?
