10/4 - Begin CHapter 22

Today we started talking about Chapter 22 - The Atmosphere.
Some of it should seem familiar to you, we talked about the composition of the atmosphere, then we focused on water vapor, ozone, and oxygen in the atmosphere. Then we started talking about atmospheric pressure, and discussed why your ears pop when you go to a higher altitude (lower air pressure).

We will continue with the notes on Monday. Tomorrow, you will get progress reports, and get back your test and quizes and homework.
