Physical Science 20 - May 26

I haven't posted in a little while.  On Tuesday, I was away from class but the substitute covered the beginning of the waves unit by looking at periodic motion and vibrations.  This was covered on slides 110-122 of the physics notes powerpoint.  Students then had time to work on Homework 5.1.  We took up that assignment yesterday and then went over the notes on some important terms used in describing waves.  As well we learned about different types of waves called mechanical waves.  There was just notes for this and they were on slides 123-132.  Today students had a study period to prepare for their exam tomorrow. Reminder of your exam tomorrow on light reflection and refraction.
