Physical Science 20 - Sept 30

Today we had an abbreviated class due to the lockdown drill.  After the drill, we jumped into learning how to do unit conversions.  The method that I used to teach this was called dimensional analysis.  It works for any type of unit conversion, from the metric to the imperial system.  I gave a worksheet for students to work on for the remainder of the class.  I strongly urge students to use the method taught in class rather than something that they learned in earlier science classes.  This will make your understanding of stoichiometry much easier.
