Chemistry 12:  We began with a short discussion about when to use Ka or Kb to find pH.  We spoke about weak acids, weak bases, strong acids, and strong bases.  We took notes on buffers, then read section 4.19.  Due Tuesday is Unit 4 # 131-134, 136, and 139.  We also got a start on the All Topics Mini-review WS.  

Chemistry 11:  Today we began with Lab 12B, where we used molecular model kits to construct molecules.  This allowed us to see the 3 dimensional arrangement of atoms in molecules.  We did Procedure # 1,2,4 only, and no questions or conclusion.  In the final part of class we did the Dead Sea Lab, and performed all our calculations on a worksheet.

Science 8:  A review of human eye anatomy was followed by a discussion of all the things that can harm vision.  We read pgs 206 - 210 and completed pg 210 # 1-7 in sentences - this is due on Tuesday.  We finished off with a world map, where we labelled all the oceans and continents.  We shaded 5 countries that we might want to travel to.
