Chemistry 11:  We marked pages 1 and 2 of the Chemical Reactions Practice Test, then everyone handed theirs in for me to mark page 3 and 4.  Click here to see the answer key.  Next class we will have a test on Chemical Reactions (units 6 and 7.)  In the second half we took brief notes on Atomic Structure, then we watched this clip about colliding atoms and fusing nuclei to make larger atoms.  We read 8.1 to page 148, and we completed Unit 8 # 13-19 & 22.  In the second half we did Lab 11A parts 1 and 2.  None of these tasks are due on Monday - spend time preparing for your Chemical Reactions Unit Test.

Science 10:  In the first half we learned about triangulation and how it can be used to find the distance to distant objects.  We tried a few problems using triangulations with the Triangulation WS.  We wrote brief notes on Stars, then read pages 338 to 341.  In the second half we finished off the Telescope Database.  Only the WS and brief notes are due next class.  No due date yet for the Telescope database.
