Day 138: Doppler Effect & Percent Yield

Physics: Doppler Effect

I introduced the equation for the Doppler effect, then students worked through some problems. A few students used a lot of color coding to keep track of all the different variables.

Chemistry: Percent Yield

Students reacted hydrocholoric acid and sodium carbonate to make sodium chloride, then calculated their percent yield. Students really liked the lab and saw the value in the calculations, which reminded me that I need to keep working on getting more true chemistry labs into this course.
