DAY 136
Goals:
1. Retake Quiz 6 and pass the quiz with a score of 100%
2. Build mastery by answering machine-related questions, and solving machine-related problems
Warm-Up:
1. none
Classwork:
1. Exam Prep
Your Machines Exam is scheduled for Friday. On Thursday evening, I'll post solutions to the conceptual questions and practice problems.
To prepare before then, review the following today:
- vocabulary listed on page 277, section 10.2. LINK
- each of the six simple machines and three classes of levers

Last day to work on Rube Goldberg in Room 37 is this Friday. If you still aren't done (why?), you can take it home for spring break. Some evidence of learning is better than no evidence. Some points are better than no points.

GOALS: SWBAT
1. To describe the relationship between period, mass, and frequency
WARM-UP: Quiz practice
1. How does increasing the mass affect f and T?
Not sure? You should do your HW :). Click the link here, and try it: LINK
CLASSWORK
1. 135B/136A: Factors Which Affect f and T (Mass on a Spring)
Friday we will continue building our math skills by doing calculations with frequency, period, wavelength, etc. With this activity, you'll solidify your understanding of those concepts. For today, you should complete the reading for the activity, and make the at least the first (if not all three) of the data tables. For classwork or homework, watch the video, then complete factor (table) #1: changing the mass
Directions:
1. Link to the handout is here: LINK
2. A video you can watch after reading the handout, but prior to attempting the work, is here: LINK If you want to speed up the video to 1.5x to save some time, go for it.
3. The simulation is here: LINK
2. Quiz:
LEARNING AT HOME (HW)/Announcements
1. There will be three (or more) extra credit assignments posted, due Tuesday after break. They will be posted below.
EXTRA CREDIT OPPORTUNITIES:
Happy spring break students! Hope you're enjoying it. Here are three ways you can build your skills and understanding of center of mass, the concept of a decibel, and the speed of light. For each well done project, you can earn up to 20 project/lab points, or 10 quiz/exam points. Your choice.
Instructions:
Read the summary, background, materials, procedure, make it your own (these are links near the top of the pages)
Complete the procedure. take at least 5 photos, to be included in your writeup.
Write up your results or make a video (bonus points!).
Present your results in class
In order to earn the full 20 points, you'll need to complete the entire procedure, AND complete one of the "Make it Your Own" activities. Projects which don't complete a "Make it Your Own" activity can earn a max of 13 project (or 6 quiz) points.
Yes, you can do all three projects if you'd like.
Due date: Tuesday.
