Great activity that had students taking apart reactant molecules and putting them back together as products to reinforce the Law of Conservation of Mass. This is our stepping stone to balancing chemical reactions. I wanted it to be more than symbols on a piece of paper and I liked what I saw yesterday and decided to invent a new activity. Our principal encourages this and says once in a six day cycle he’d like to see us stretch a little (with the understanding that we may fall flat on our faces but with no risk comes no reward). Part of students’ grade was the photo I took of their work.
Students in IS II are really enjoying the NOVA production. “Hunting the Elements” with David Pogue. It is long (nearly 2 hours) so we watch it in 25-30 minute segments every few days. We were streaming it from the PBS website but our school’s broadband was having issues so we bought it via Amazon for $1.99. Best purchase ever. The video captures their attention, and aids in their understanding of basic bonding and chemical reactions. I follow David Pogue on Twitter (
@Pogue ) and he has been gracious enough to respond to a few of my inquiries. When he is ready for a group of teachers to help him with any of his ideas or productions, I’m in!
