Force Diagrams

I collected and we debriefed the Newton's First Law Lab.  I also showed a video lecture from Paul Hewitt, the author of our textbook.  If you do not take notes during the lecture, the alternate assignment is to read Chapter 3 and answer the Review Questions on p. 35-36 #1-15.

I also explained how to make a Force Diagram.

HW: WS 1a

Newton's First Law Lab (Orange: 10/22 Black: 10/27)

We took a diagnostic test about forces then did the lab.  The lab has 10 stations around the room that all demonstrate Newton's First Law.

HW:  None

2.  Write the score for each homework in the upper right hand corner of the assignment.  Score your homework packet as follows:

Homeworks with stamps and corrections = 100

Homeworks with stamps but not corrected = 75

Homework complete, but no stamp = 50

Not complete = 0

Quizzes scores are not included in the homework packet!

3.  Add up the total number of points for your packet and write it at the top of the first page.

Doppler Shift (Orange: 10/20 Black: 10/21)

Today Mr. Rann guest lectured on the Doppler Shift.  He showed some cool animations and youtube videos that he made.  After that we reviewed for the test by going over the more challenging questions on the review sheet and grading quiz #4.  I passed back most of the labs from this unit for studying as well.

The practice test is available for download.  I left out the matching section, but you can check your answers to the vocab on the review sheet link below.  The practice test is closely aligned, but not identical to the real test.  Be sure to come in during tutorial to check your answers!

HW:
Study for test
Check your answers to the review sheet here (Download a blank one here).
Assemble HW packet (I will put up a second post by Sunday night.)

Test is Monday p. 2, 4, and 6 and Tuesday for p. 5

Rainbows (Orange:10/18 Black 10/19)

I checked the homework, but students will need to correct their homework online by clicking here.  I gave the quiz on colors, then we spent most of the period doing the Rainbow Lab.  First, we made rainbows without rain by observing thin-film interference.  The second part of the lab involved going outside to make rainbows using a spray bottle.

HW:
Review Sheet (Due 10/20 for Orange, 10/21 for Black)
Read p. 432-436; Answer the review questions p. 438 #22-27

More Color Mixing (Orange: 10/14 Black: 10/15)

We finished (p. 2,4 and 6) the True Colors lab, then discussed Parts 1,2 and 4.  During the discussion we also corrected the WS 6 and talked about the questions that weren't assigned.  I demonstrated how shadows are made using different colored lights, similar to the worksheet.  This took most of the period.  We talked about our field trip to the Exploratorium on November 18 (an Orange day).  The cost of the trip is $30 and the money and permission slips are due on Friday, October 23.  The last thing we did was grade quizzes 1-3 in class.

HW:
Read pp. 399-408; Review Questions on p. 416 #1-15
Study for quiz on colors (Reading, Lab, WS 6)

True Colors (Orange: 10/12 Black: 10/13)

We switched seats today.  I also collect the homework (the reading) and debriefed and collected the lab.  I passed back the test and went over it, as we revisited two topics from the particle model of light unit, shadows and refraction.  The lab was called True Colors, and we looked at the dispersion of white light through a prism, and used the optics benches to do additive color mixing.

HW:  Complete Worksheet 6 (skip 5-9 for now).

Casio Lab (Orange: 10/8 Black 10/11)

We started the period with the Wave Interference Quiz.  I talked a little about sound waves and hearing, then we spent most of the period doing the Casio Lab.

HW:  Reading and summary on Loud Music and Hearing Loss

Resonance (Orange: 10/6 Black: 10/7)

I checked the homework, but you will need to correct it by checking here.  I discussed the Standing Wave lab and collected it.  I also discussed the Wave Tank lab (either the NVIDIA or PhET versions), with the most important concept from the lab being diffraction.  The first 2 minutes of this clip provides a great explanation of diffraction.  After that we took the Post-Test for NVIDIA to review the results.  Most of the period was spent discussing resonance, and I showed a number of examples, including the Mythbusters resonance episode, and this one of the Tacoma Narrows Bridge collapse.

Constructive and Destructive Interference (Orange: 10/4 Black: 10/5)

I checked the homework (WS 25-1) and we corrected it in class.  The quiz was based on the homework and the lecture from last week on wave relationships.  Following that, we discussed constructive and destructive interference and standing waves.  The second have of the period we did the Standing Wave Lab and two on-line activities.

HW:  Finish the online activities, wave adding worksheet.
