N.R.'s experiment shows us a "volcano" (made out of Playdough) exploding by using baking soda and vinegar. It was cool that, as she put more of the white powder, it "exploded" more and more! This taught us about the science of chemisty.
With M.M's experiment he put food color in milk. Then he put soap on a stick, and when the soap got close to the colors they moved away and mixed! A.J. did some research and found out that the soap isn't as dense (or "thick") as milk, so the colors just stayed on the top and mixed together that way. P.F. thought that this experiment was awesome because it was fun to see the colors move around and combine together. It was like magic!
P.F. says that his "underwater volcano" experiment was excellent because it exploded better in class than it did in the house. He used cabbage juice to make the liquid red, and it was fresh because it exploded so much and then it turned pink.
