Week 2

      This past week in Chem A we continued classifying matter and everything from elements to macaroni salad to rocky road ice cream.  We saw how elements can be considered the building blocks of the building blocks of all matter.

      All students successfully passed the safety quiz earlier in the week and in no time we were in the lab looking at how what we see as physical and chemical reactions can also be viewed with atomic level representations.  I got to break out 1970's camera and describe to students the chemistry of flashbulbs!  Remember those!

   Next week is going to be busy as we continue in all things measurement and how important that is in lab!
