Welcome back from Spring Break. Hope you were able to take some time to relax and do some things you enjoy. We baked, played a lot in the back yard, and did a TON of CLEANING. Happy wife, happy life.
If you haven't seen it yet, there are some COVID-19 resources available on Venice HS's website: https://venicehs-lausd-ca.schoolloop.com/pf4/cms2/view_page?d=x&group_id=1535349876217&vdid=i17b2g9xq3k4
Also, office hours for when your teachers will be rapidly responsive to your questions are listed here: https://venicehs-lausd-ca.schoolloop.com/pf4/cms2/view_page?d=x&group_id=1535349876217&vdid=i1v7b2gh79xq42t As you know, I answer Remind messages and emails just about all the time, but my official office hours are Monday 1-2, Wednesday 10-11, Friday 10-11.
This week's schedule:
Mon: Finish IMA (Ideal Mechanical Advantage)
Tue: MA and IMA Quiz
Wed: Review Machines. Quiz retake.
Thurs: Waves Intro
Fri: Machines Exam
#Goals: SWBAT...
1. recite the IMA equation
2. interpret the IMA equation, as it relates to a multi-gear bicycle
3. solve problems using the IMA equation
4. interpret the solutions to explain their meaning
Warm-Up:
1. Can a machine make a task require less work?
2. If yes, how? If no, why not?
Classwork:
1. 133A: How It Works - Bicycle Gear Shifters
A. Read the intro at the top, then steps 1-4. Textbook link to page 276 --> LINK
B. Watch the lesson (17min) here: https://youtu.be/ynN645yLjJM
C. Answer questions 1 and 2 on page 276. Check your answers in my video above.
2. Catch up.
If you haven't taken our 118A: Thermodynamics Exam, please do so by Tuesday.
Same goes for any other the other assignments.
Question? Remind App.
3. Have a Great Day!
GOALS: SWBAT
1. differentiate between transverse and longitudinal waves
2. define longitudinal wave terms
3. label the components of transverse and longitudinal waves
4. measure the velocity of a wave
WARM-UP
Go to: https://www.difference.wiki/longitudinal-wave-vs-transverse-wave/
Draw transverse and longitudinal waves.
What is a rarefaction?
What is a compression?

CLASSWORK
133A: Wave Basics - Spring Lab
Read the entire lab document (3min): https://docs.google.com/document/d/1Z_AysvIR0qjpSGaHpQyVivFugnXvHYs3nzfr5LHKgQk/edit
Make a copy, and share it with me.
In groups of 3-4, check out a spring, and complete the lab.
You should finish all data collection, and perhaps all questions as well, today. Lab is due Thursday.
LEARNING AT HOME (HW)
1. Complete 132A and B. Wednesday, we will do more wave calculations, so you'll want your wave math skills to be sharp
