    LEGO atoms and molecules

  • We used about 1/2 of 100g of CaCl2 for 5 different tests in the LEGO Chemical Reaction module by Vandiver and MIT. We also used Jiffy Juice 15instead of phenol red. This was our first chemical reaction to write chemical formulas and learn about conservation of mass. We paired this with lesson 19 of Friendly Chemistry. High grade CaCl2 got us heat, gas, color change, and 4 new products to test. I'd already tried deicer from local sources and got very little heat or gas production. Many Thanks for making this hands on lesson so productive for us, Melody

  • At http://www.science-house.org/learn/CountertopChem/index.html you will find a whole bunch of great experiments. Most use real chemicals, and I have been able to find all of these at home science tools. In fact, at least once I've seen a post on a chemistry site lamenting how hard it was to find a specific chemical, and someone else had already told them to come to this site. This chemical was used for one of the "Zip-top bag" experiments, and the kids really enjoyed it. I do keep the chemicals located in a hidden spot, out of reach of children, with the lid securely fastened.
