Science 8:  We went through page 205 # 105, then we wrote notes on the Human Eye.  We labelled an eye diagram, to practice identifying anatomy, then we read pages 206 - 210.  We completed page 210 # 1-7 and finished page 197 # 1-10.  Clear diagrams are a useful way to explain ideas with less words.  In the second half we discussed the difference between near sightedness, far sightedness, and astigmatism.  This video shows how laser eye surgery can correct the cornea to eliminate these issues.  We raced around a paper track using a plane mirror to view our hand and had trouble with direction.  Lab 6-2, page 207 was the final task, and this can easily be accomplished at home.  Only page 210 and 197 are due next class.

Chemistry 12:  We took brief notes on the Relative Strength of Acids, then we read 4.10 and completed 38-44, 47, and 48. Extra time as used to finish Lab 20G.  In the second half we learned about pH and pOH.  We read 4.11 and completed # 49-57.  The textbook work is due Friday, and Lab 20G is due on Monday.
