As part of the wrap up of our science unit of study on matter, we made slime today (and noted how it's a chemical change)! What a wonderfully, messy, fun time the kids had! :) Here's the recipe we used. If you try it at home, and don't want it runny, it takes A LOT more Borax than the recipe calls for. I used about a box and a half for the four groups, with all of the other ingredient amounts staying the same.
