Physical Science 20 - Feb 29

Happy Leap Day Everyone!!  It also happens to be the day that we started to learn about the mole.  We had some time to go over the assignment from Friday on metric conversions but then moved on to learn about what the mole is.  This was covered in a new powerpoint called The Mole.pptx found in the notes folder of the chemistry folder in the Physical Science 20 Course notes link on the right hand side of the webpage.  We covered slides 1-12 today and students spent most of the class working on Assignment C17, which we will go over tomorrow.  Tomorrow in class we will learn how to use the molar mass to convert between mass of a substance and moles of a substance.
