Science 10:  Today I collected the Half-Life WS.  pg  317 # 2,4,5,10 due Wednesday.  We are working through some Year End Review:  some of you started with Motion and others with Chemistry, but neither of these are due tomorrow.  Spend some time on final exam prep.

Science 9:  pg 247 # 3-7 is not due Thursday.  Today I collected pg 244 # 2,4,5,7-11 from most of you... some will give it to me on Thursday.

Chemistry 11:  WS #4 on Alkenes and Alkynes.  I collected Lab 7B today.

Physics 11:  We worked on 4 problems from a hand-out involving Relativistic Addition of Velocities (due Wed).  We also did a review/lab activity where we found the index of refraction, the critical angle, and the speed of light in a non-air material (not due Wed).
