"Blue Bottle" Trailer (Teen Class)

Students experiment with the properties of lye, a strong base -- how to handle it safely, how to measure it, and what happens when it's mixed with other chemicals. They also try to solve the puzzle of why a solution inside a sealed bottle changes color when they shake it and then changes back again. This relates to bases, mixtures, solutions, chemical reactions, oxidation, heat and cold, using a digital scale, and safe handling of caustic chemicals. This video also includes one of Mr. Mac’s crazy stories, “Evil Mister Fred’s Blue Blood,” to help students remember the lesson. Difficulty: Medium
