Intro to Waves

After listening to summaries from our 33rd week of science news articles, we began Chapter 9 on Waves.  We discussed section one notes, which differentiates between transverse and longitudinal waves.  I provided a demonstration of each using a giant slinky coil.  Students were then assigned page 9-1 to do with their partner, and we reviewed the answers before class ended.
No homework was assigned.
