Fireworks and atomic Theory


Friday, October 1, 2010

Dear, Class

Today we started class by stamping and going over the homework which was page 1 and 2. Then we had to rush through some notes so we could get onto our fireworks lab. I was expecting explosives in the fireworks lab, but there weren't any so that was a big let down. In the Lab we tested Li+, Na+, K+, Sr 2+, Cu 2+. We didn't test everything on the sheet because apparently it was to expensive to buy. To test what color each of those burned we dipped a metal rod in some water then into the salty looking chemicals then put the metal rod over the fire and watched what happened to the color of the fire. Each one produced a different color fire. At the end of the period Ms. Mando showed us three different chemicals and we have to guess what they are for our homework. Remember work on your chem think and webassigns. work book 3-4 due 2marow and finish the lab for 2morrow

Love, Dan b
