Science 90 - Nov 4

Today students finished their notes on molecular compounds.  We then looked at chemical formulas and how to count atoms in a chemical formula.  During the last 30 minutes of class, students were assigned a worksheet on counting atoms in formulas as well as some questions from the textbook.  Student are to read pages 167-172 in the textbook and answer questions #1-4 on pg 171 as well as questions #1-5,9 on pg 173.  These questions will be checked on Thursday.  Tomorrow students have a day off from class and an experience in the workforce.  Have fun with the real world.
