Science 10 (P56): After a short lesson on Polyatomic Ions, we tried 5 names and 5 formulas of ionic compounds that contain these ions.  We also did pg 191 #5 from the old Probe 10, and self checked the answers with an answer key.  We spent the second half doing Lab 8.1 - only the WS is required for analysis, not the Questions below the Procedure.  We finished with part II of the experiment with the falling meter stick.   There will be a Quiz on Names and Formulas of Ionic compounds on Friday.  We watched a short video on Copper at the end.

Chemistry 11:  Today we took notes on Molar Concentration.  We read pg 96-98 and did Exercises # 59 and 61-64, which is due on Thursday.  Lab 4D is also due on Thursday.

Science 10:  I collected pg 174 # 1-12 from the (old Probe 10 Text) today.  We started with a little experiment to gather data on reaction time.  Expect this again next class.  We spent some time on the techniques for writing formulas and naming ionic compounds, and we did 10 for practice.  At the end, we read pg 123 to 124.
