Physical Science 20 - Feb 14

Happy Valentine's Day everyone!  This was a special day as students were given most of the class to work on Homework C15.  We did a couple more examples of how to complete double replacement reactions.  Then students were given time to work on Homework C15.  We will take this up tomorrow.  If students finished early, they then worked on Assignment C2.  This will be handed in on Thursday.  Tomorrow we will begin looking at math skills that will be required for chemistry.
