Chemistry 12:  After a short review of electrochemical cells we looked at our Hoffman Apparatus.  This electrolytic cell uses direct current to split water into Hydrogen gas and oxygen gas.  We took notes on Electrolysis, then we read 5.13.   We worked on the Electrolysis Mini Review, then the Electrochemistry Practice Test, then the Practice Final #1 (and some students are working on #2).  Due next class is all but the Practice Final.  

Science 8:  We reviewed atomic structure first, by looking at our posters of atomic structure.  We made a table of minerals at we wrote descriptions of feldspar, mica, sulfur, sphalerite, quartz, and galena.  We reviewed the rock families and read about volcanism and forming igneous rocks.  Everyone made their own rock cycle diagram. In the second half we write the Geology Practice Test.  On Monday we will write the Geology Unit Test.
