Wave Relationships and Virtual Wave Tank (Orange: 9/30 Black: 10/1)

Today we started with a quiz on the basic parts of a wave.  I continued to lecture on wave relationships, frequency, period, and velocity.  Most of the period was spent completing a lab that shows how waves behave using a virtual wave tank.

HW:  Finish WS 25-1 (Read 25.1-25.9 for help)

Quiz on wave relationships (period, frequency, speed)

Review for Particle Model Test and Begin Waves (Orange: 9/24 Black: 9/25)

I checked and we corrected the review sheet.  We also took and corrected the Refraction Quiz, and graded Quiz #3.  We discussed a few more refraction examples, then talked about problems with the particle model of light.  We began our Waves Unit with a pre-test that will be used with the research that Stanford University and NVIDIA are doing in our classroom.

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.

More Refraction (Orange: 9/22 Black: 9/23)

I checked and we whiteboarded WS5a.  Following that, I did a few demonstrations of refraction and critical angle.  I gave about 25 minutes to work on homework, the review sheet for the upcoming test.

HW:
Review Sheet
Study for Refraction Quiz (WS5a)

Discuss Refraction Lab (Orange: 9/20 Black: 9/21)

I started the period by discussing the results of the Refraction Lab, then collecting it and the Reflection Lab.  The Refraction Lab need the graph attached to it, the Reflection lab has the white paper that you used to trace the light rays attached.

Most of the period was spent working on the homework (Worksheet 5) in class.  We also graded Quiz #2 in class.

Homework is to finish WS 5.

Refraction Lab (Orange: 9/16 Black: 9/17)

We started the period off with a quiz on WS 4a and I checked to make sure everyone had a protractor.  Following that I did a few demonstrations using refraction of light.  The majority of the period was spent doing the refraction lab.

HW:  Finish the lab

First Whiteboarding Session (Orange: 9/14 Black 9/15)

Today started with a quiz on the Law of Reflection.  Following that we discussed how whiteboard presentations work and what is expected of each presentation, presenter and the audience.  We spent almost an hour preparing and presenting Worksheet 4a.  Click here for the answer key!

Debrief Reflection Lab and Drawing Ray Diagrams (Orange: 9/10 Black 9/13)

We started the period with the quiz on Worksheet 3.  I also checked the homework and we briefly went over it.  We debriefed the reflection lab and discussed how to draw ray diagrams.  I gave a lot of time in class to work on WS 4a.  If you did not finish WS4a it is homework.  The quiz will be on the law of reflection (review your lab).

Plane Mirrors (Orange: 9/8 Black: 9/9)

I checked Worksheet 3 homework, but we did not go over it. The answers can be found on my website, or click here to be taken directly to the answer key. I also collected the paragraph summary and the light intensity lab. We took the quiz on pinholes. The quiz for the next block will be on WS 3, so be sure to correct your answers. The remainder of the period we worked on the plane mirror lab. From this we learned the Law of Reflection and that the virtual image is the exact same distance "behind" the mirror as the real object is in front of the mirror.

Homework:
Read 29.1-29.4 (pp.419-424); answer the Review Q's 1-9 p. 437
Finish Lab
Quiz on WS 3

Light Intensity Lab (Orange: 9/3 Black: 9/7)

I gave the quiz on properties of light and shadows. I checked WS 2 and went over it. There will be a quiz on one problem from this worksheet the next time I see you. I also showed a video Mr. Hammack and I made that shows how pinhole viewers work. The one thing that was not discussed in the video is how the pinhole representation gets more intense (brighter) when the viewing screen is close to the pinhole. To explore this we did the Light Intensity Lab and discovered the Inverse Square law.

Homework:
Finish WS 3

Study for Pinhole Quiz

Pinhole Viewer (Orange: 9/1 Black: 9/2)

I started the period with a quiz on the Green Sheet and collecting "Getting to Know You...".  We spent a considerable amount of time debriefing the Shadow Lab and the back side of "Properties of Light" notes from the first day.  The remainder of the period we made pinhole viewers, then constructed a physical model to explain what we saw in the viewers.  The last 10 minutes was spent playing a Who's Who, so students can get to know each other.

Homework:
Complete Worksheet 2
Finish the Shadow Lab Discussion Questions
