 * Stewart** - Laser Golf Reflection Activity - the following is a diagram of where to place the obstacles for each hole. There's no instruction sheet, just the diagram sheet. Each student group is to create a 9x5 grid on their table. They then setup the obstacles as shown in the diagram for that particular hole. They may use up to 3 mirrors to aim a laser in the hole.


 * Stewart** - Scattering Activity that explores the question, why is the sky blue?

Lund- Used with an Ipad app (free oscilloscope- I used Physics Oscilloscope) Introduces relationship between frequency/pitch and amplitude/volume using book and then on oscilloscope were students can actually see it happening.

Lund- This is what I have been using to help students track grades and understand requirements with SRG. Properties of Waves: Also posters for my walls. Interactions of Waves: Posters


 * Sound and Light CFAs**

Freilinger and Snyder (Hiatt) These are the CFAs we have used over the previous two years. Some of the questions are not the best, but use what you can. CFA 4A 2012-2013

CFA 4A-B 2012-2013

CFA 4A-C 2012-2013

CFA 4A-E 2012-2013

CFA 4A 2013-2014

CFA 4A-B 2013-2014

Visual aid for CFA 4B

Visual aid option #2 for CFA 4B

Lund - Visible Spectrum comparison of wavelength/frequency to color [|http://heasarc.nasa.gov/docs/xte/outreach/HEG/efw/efw_intro.html - This is where the idea for the above came from. (This is a puzzle students can solve and see the change in frequency and wavelength with the electromagnetic spectrum]

to be used with reading from __Oh, Yuck! The Encyclopedia of Everything Nasty__ by Joy Masoff titled "Eye Gunk" page 49-53. for extra practice with wave interactions for students, can be used as a quiz or activity.

4A: I can distinguish between types of waves.

4B: I can describe the characteristics of waves.

4C: I can compare and contast sound and light waves.

4D: I can compare and contrast transmission, absorption, reflection, refraction and scattering of waves.

4E: I can explain how the color of an object is determined.

4F: I can trace the route light must take in order to be seen and the role the eye plays in vision.
