Chemistry 12:  We started with a short discussion about the final two weeks of the course and our final exam on January 24th.  New today was balancing half cells and balancing full cells.  Due Tuesday is # 19 (any 3 acidic and any 3 basic half reactions) as well as #24 (any 3 acidic and 2 basic full redox reactions).  Now is a good time to begin preparing for your final exams - we spoke about the number of sleeps within review cycles as a major factor in retaining information.  Have a regular meeting with a classmate at lunch, and study for 15 minutes together.  Fun and effective.  

Chemistry 11: We started with a short discussion about the final two weeks of the course and our final exam on January 25th.  We took notes on Cis and Trans Isomers, then we read pgs 229 and 230.  Click here to see WS#6, which needs to be completed for Tuesday.  

Science 8:  After reviewing 9 mountain peaks visible from RSS we learned about plate tectonics.  We read section 17.4 from the old Probe 10, and we worked on pg 508 # 1-9,11,12 which will be due on Thursday.  We watched this clip that shows divergent plate boundaries, as well as this one showing many types of plate interactions.  This clip has a terrific depiction of convection currents in the mantle that push the plates apart and shows subduction well.  This is a good clip for understanding mountain formation.
