It's Monday, so we listened to the summaries of our week #7 science news articles. We discussed section 2-3 notes on Physical vs Chemical changes. I demonstrated how folding, cutting or crumbling a piece of paper is just a physical change, because it was still paper - nothing internally had changed. Then I burned the paper to show how an entirely new substance was formed, making it a chemical change. http://www.brainpop.com/ had a great video on "Property Changes", so students watched it and took the quiz that followed. We had just enough time to complete pages 2-3 & 2-4 with partners and go over the answers before the end of class.
No homework was assigned and the Chapter 2 test is on Thursday, October 27th.
