Chemistry 11:   Today we wrote a Conclusion for Lab 3A, using the Lab Marking Guide and sample Discussion found on the back of the Lab Marking Guide.  I collected this today, but will gladly take it on Friday if it is not done.   We did Lab 2E today, including all the Questions and Calculations, Follow up Questions, and a Discussion.    Lab techniques to write about:  why heat the container?  why have the lid on, then slightly off, then fully off?  why add water and then evaporate it off with high temperatures?  Lab 2E is also due at the start of class on Friday.

Chemistry 12:  After a review WS (HW Quiz Unit 1 # 41-45) we learned about catalysts, watched a video describing the mechanisms at work in a Catalytic Converter, and read sections 1.10, 1.11, 1,12.  Unit I # 54 - 61 are due on Friday.  We did a pink WS on mechanisms, which is due on Friday.  Half of the Practice Test is due on Friday.  We will have a unit test on Rates of Reaction on Tuesday.
