Science 90 - Oct 31 & Nov 3

On Friday in class we learned about the structure of an atom and how to determine the amount of various subatomic particles.  This was accomplished by going through the notes on slides 45-52 in the notes powerpoint.  We also learned the difference between an atom and an ion.  Students were then given the rest of class to work on Worksheet 1.  This was a table that students needed to complete by filling in various amounts of information based on atomic structure.

I checked that work today.  We then went over the answers and I assigned the backside of the worksheet.  This is due tomorrow.  I am taking this assignment in for marks.  We also learned how elements come together to form compounds.  There are two types of compounds and we learned about.  The first type are called ionic compounds.  These types of compounds form between metals and non-metals.  This was covered on slides 55-58.  I ended the lesson early so that students could work on the atomic structure assignment that is due tomorrow.

I have also set the date for the quiz in the unit.  It will occur on Friday, Nov 7.  The following information will be on the quiz

•Lab Safety and WHMIS

•Mixtures and Pure Substances

•Chemical and Physical Properties

•Atomic Models

•Atomic Structure
