  1. Today is October 3, 2012 • You need to finish your review sheet from yesterday ON YOUR OWN! • There is no talking for the beginning of class • I’m going to walk around and see what you have done to take a grade so get busy

  2. Give me five properties ofMETALS • Shiny • Good Conductor of heat and electricity • Ductile • Malleable • High Melting point
