 Chemistry 11:  We learned about using the dilution equation and finding the [ions] in solution.  Due Thursday is pg 102 # 78-81 as well as the WS titled Finding the Concentration of Ions.

Chemistry 12:  We made a Carbonate and Bicarbonate buffer, to show how buffers are made.  The buffer resisted a change in pH when acid or base was added.  After we wrote some notes on Buffers, we did the Buffer Mini Review to try out our skills. A little was given for completing the Acids and Bases Practice Test, which is due Thursday.  Click here for a practice test key.  We will have an Acids and Bases Test on Thursday.

Science 8:  We did the Chapter 1 & 3 Practice Test today, and it is due Wednesday.  I returned your Immune System Flippits, and we spoke about how you can use your flippit during your test on Wednesday.
