Chemistry 12:  We had a short discussion about collision theory, and I used this animation to show the effects of increasing temperature, or pressure, or concentration.  We read sections 1.3, 1,4 and 1.5 in Hebdon, then completed # 10 - 22.  These are due on Monday.  Click here to see the assignment log.

Science 8:  Page 249 # 1-5 was handed back today with helpful comments - please adjust your writing according to the comments I provided.  Quite a good effort overall on your first textbook assignment.   We spent more time learning how to measure to the nearest one tenth of the smallest division, and we measured some liquid volumes with graduated cylinders and beakers to try our skills.    We took brief notes on Measurment, then completed the Measuring Volumes WS.  Due on Monday are page 251 # 2-4 and 253 # 1-4, (half in sentences).   Click here to see the assignment log.

Science 10:   We reviewed how to measure liquids in chemistry labs, then we practiced measuring a few volumes.  We learned about polyatomic ions and how to find them on page 3 in our databooklet, and we tried 5 names and 5 formulas of ionic compounds .  In the last 20 minutes we viewed 10 ionic compounds and recorded the ion formulas, names and compound formulas.  This task was collected at the end of class.  Click here to see the assignment log.
