DAY 165

GOALS: SWBAT...

1. determine the charge (+ or -) of two materials after they interact with each other

2. use friction to create a charge imbalance in two objects

WARM-UP

1. Define the following. Look up physics definitions if necessary. Write your definition in your own words

a. affinity

b. electron affinity

CLASSWORK

1. Review: GR Electrostatics:

Check your answers to last night's guided reading: LINK

2. Review: What is Static Electricity:

3. 165A: Charging by Friction

- type your answers into the Google Doc on Schoology (can't access it on schoology? alternate link is HERE)

- answer all questions from the following LINK

- unsure of how to answer these? Here's your assistance in two readings:

- Charging by Friction LINK2

- Structure of Matter LINK1

- Slideshow: LINK3

How attracted are you?

Practice (do any 6 for proficiency, or all 12 for mastery). Solve these on paper. LINK

Last Day!!!!

Goals:

1. Make a motor

2. Explain how it works

WARM-UP:

Watch this video: What's making the coil spin?

CLASSWORK

165A: Making a Motor: Stripped Down Motor Lab

- Document is on schoology, so get it there. Read the instructions after we watch the video

- after you get the motor working, think about HOW it works. Here's some questions to help you think about that.

- Electrons flow where?

- What kind of field do flowing electrons create?

- What kind of field does the magnet make?

- Would two fields interact? How?

- What role does the sharpie marker play?

- Submit your document via schoology by Sunday 11:59pm

- Extra credit if you show advanced level of knowledge

Can't access Schoology, here's the link to the lab doc: https://docs.google.com/document/d/1FxAU_BrpxY-s-vqgVbQ7I-IY8uOTAbv3DAnfq42df3I/edithttps://docs.google.com/document/d/1FxAU_BrpxY-s-vqgVbQ7I-IY8uOTAbv3DAnfq42df3I/edit

Learning at Home (HW)

- Study for your final. Final Review docs are on day 162

- Complete your Stripped Down Motor Lab by Sunday

- Want more motor building fun?
