Physical Science 20 - Oct 27

We had a couple of interruptions to contend with today in class.  In period 2, most of the class was absent due to the late start we had because of the awards ceremony.  Students spent most of the time preparing for their stoichiometry exam tomorrow.  In Period 3, we had to do the Tell Them From Me survey, which took up a significant portion of the class.  Afterwards we returned to the class and continued with the introductory physics activity from yesterday.
