Physical Science 20 - Sept 22

Today in class we learned a method for converting units.  This method is called dimensional analysis or unit analysis.  We went through a couple of examples and then students worked on the handout called Metric Conversion Homework.  Period 2 did the odd questions and Period 3 did the even ones.  The notes were on slides 37-49 of the Math Notes Powerpoint located in the Chemistry Notes folder.  The assignment is also located in the same folder.  Tomorrow we will start looking at the concept of the mole.
