Science 8:  We looked at lab 13E and sketched out where the liquid outer core must be, so that S-waves are blocked from reaching seismic stations F and G.  We took brief notes on the structure of the earth, then drew a scale diagram of a cross section of the earth (we used 1 cm = 1000 km).  Near the end we watched this clip, which introduced Plate Tectonics and helps explain the mechanism for continental drift.  Only the scale diagram is due on Wednesday.

Chemistry 12:  The Oxidation Number WS answer key was reviewed first.  We learned how use the Standard Reduction Table to predict the spontaneity of redox reactions. Section 5.3 was read, and we completed Unit 5 # 7-14 (due on Wednesday).  In the final minutes we looked at the Acids and Bases test.

Chemistry 11:  We did the Precipitation Reaction Mini lab and practiced writing Formula, Complete Ionic, and Net Ionic equations.  The answer keys for the Atomic Theory and Solutions Review were posted for everyone to see.  Test on Thursday.
