Video Lecture for today: https://youtu.be/wTkiDbxGYS4
Goals: SWBAT...
1. Describe the cause of static electricity
2. solve electrostatic force problems
WARM-UP:
1. How many word parts in the word "electrostatic"?
2. Define each word part (electro and static)
3. One Coulomb is about the amount of charge that passes through a common 100 watt lightbulb in about one second. What might you feel if 1 Coulomb of charge passed through your body?

2. 164B: What is Static Electricity:
Watch the video here: https://ed.ted.com/lessons/the-science-of-static-electricity-anuradha-bhagwat#watch
While watching, in your notes, answer the 7 "Think" questions listed in the Think section of the website (you can also click here (LINK) for the questions. To answer #2, review the brief paragraph below:
"Dry air preferred. Static electricity is formed much better when the air is dry or the humidity is low. When the air is humid, water molecules can collect on the surface of various materials. This can prevent the buildup of electrical charges. The reason has to do with the shape of the water molecule and its own electrical forces."
3. 164C: How attracted are you?
Do any 6 for base level (proficient = 5pts), or all 12 for mastery (and 10pts).
Solve these in your notes. LINK
