We began today's class by reviewing yesterday's class in the form of worksheet 3-5. Students took about 5 minutes to complete that page before we reviewed the answers together. We then did worksheet 3-6 all together, which reviewed last week's topics, including mixture vs compound and heterogeneous vs homogeneous. I introduced students to a coefficient (from section 3-3 notes), and I showed three different examples on the board of how coefficients change the atom count in a formula. Students then used this concept to complete worksheet 3-8 before we reviewed the answers. There was just enough time left at the end of the period to watch a http://www.brainpop.com/ video on Chemical Equations, which is what the past two days are leading up to tomorrow.
No homework was assigned, and the test is scheduled for Thursday, December 9th.
