Physical Science 20 - Sept 26

Today students began class by reviewing the conversion technique we will be using in class.  We worked on a metric conversion assignment.  After about 20 minutes on this assignment, we moved on to learn the concept of the mole.  I introduced this concept to the students and then we learned how to calculate a substances molar mass.  At the end of class I assigned Assignment C17 and told the students to work on every second letter.  Tomorrow we will learn how to do molar conversions.  There is a new powerpoint that we are using.  It is called Chemical Quantities and today we did slides 1-12.  It is found in the Notes folder of the chemistry link in the physical science 20 course notes folder.
