Science 9:  We handed in the Bar Graphs today that showed the Carbon storage for each biome.  We took notes on the Nitrogen Cycle, read section 4.3 in the old Probe 10 textbook, and completed pg 95 # 2-10, 15, and 17 (Due Wednesday).  

Chemistry 12:  We started off the Electrochemistry Unit by constructing a Copper half cell and a Zinc Half Cell, and connecting them to make a cell that produced nearly 1 V.  We read 5.1 and completed # 1,2.  In the second half we learned how to do oxidation number, which is a technique that is useful in determining which species are oxidized and which are reduced.  The Oxidation number WS is due Thursday.
