Chemistry 11:  We began with a short review of key Moles Unit terms and percent composition of lead in the mineral Galena (PbS).  We spent most of our time completing the Moles Unit Practice Test, which is due Tuesday.  The Moles Unit Test will be during the double block. 

Science 9:  Today I collected pg 217 # 1-11 and 14-18.  We watched two videos, one on Neon and the other on Argon.  We drew Bohr Diagrams for each element up to atomic number 20 and recognized trends in the outer shell, called the valence shell.   After this we looked at local lakes, mountains, and streams on a stylized map of our Area.
