Musings and reflections of a middle school science teacher.

The idea of RED SHIFT was hard for my students to visualize. I found a short, easy demo to demostrate it, and wrote it up into a quick lab. You can find the Modeling Red Shift lab on my webpage. I used elastic instead of a rubber band, and I glued a sparkly star to the middle of the elastic for fun.
The timer on the board in the background is from Online Stopwatch. I often use it to help the students manage their time.
