Chemistry 11:  After a brief review of safety topics, we created a 3 column on our notes from Friday (headings:  Name/Physical Properties/Category) and we looked at about a dozen different materials and recorded their physical properties.  A little time was provided to finish reading Unit 1 (pages 1-8 in Hebdon) and complete the map as per the instructions in the text.  In the second half we learned about how scientists measure (to the nearest one-tenth of the smallest division) and how the last digit in scientific measurements is called the uncertain digit because it depends on the measurer's opinion.  We started the Measurement Intro WS.  

Chemistry 12:   We wrote brief notes on Factors that affect rates of reaction, then we read section 1.3 and completed # 10-13.  The remaining time was spent completing Lab 7.  Both the lab and the Hebdon questions are due Tuesday.

Friday, September 11th

Chemistry 12:  Unit 1 # 1-9 was handed in first.  After a successful fire drill we completed Lab 7A from a hand out.  We recorded data and started the analysis right on the Lab 7A hand-out.  Lab 7A is not due Monday, we will work on it during class. No work is due for Monday, but please ensure your supplies are all sorted out.

Chemistry 11:  We reviewed safety topics and read through the safety rules at the start of the Heath Lab Manual.  The rules were categorized according to how familiar students are with them (Most Students know, Some Students Know, Few students Know) and we had a special column for rules that are completely new and unfamiliar.  We wrote brief notes on Chemistry before the end of the period.  No work is due for Monday, but please ensure your supplies are all sorted out.
