Physical Science 20 - Feb 8

Today I continued on with chemical reactions and showed how to transform a paragraph describing a chemical reaction into a word equation and then from there into a balanced chemical equation.  We also learned abou the five different types of chemical reactions.  This should be review from last year.  This was covered on slides 27-41 in the notes.  Students spent the remainder of class working on Assignments C10 & C11.  We will go over these tomorrow and look at some demos of the different types of reactions.
