Chemistry 11:  We discussed the development of atomic theory over time, and how our understanding changes as new technology allows better measurements and new observations.  We saw a Cathode Ray Tube in action, producing a beam of electrons.  We viewed this animation showing Rutherford's Gold Foil Experiment.   We spent time reading pgs 139 - 147 and completing # 13-19 in quality point form.  We will have a Test on Reactions (Chapter 6 & 7) tomorrow, Tuesday.

Chemistry 12:  We carried on with Lab 20G today.  No work is due for the lab, but ensure that Unit 4 # 28-30 is done.

Science 8:  Today we learned about concentrated and dilute solutions. We viewed this animation to show how in mixtures the molecules move from high concentration to low concentration through random movement.  We read pg 56 & 57 and created a placemat (for each system, write the name, function, and two parts).  Due tomorrow is pg 39 # 1-10.
