This week in science we started our unit on Matter. We mixed 125g of cornstarch with 100 mL of water to see what we would come up with. The students had a lot of fun trying to decide if it was a liquid or a solid. The students discovered that the mixture behaved like a liquid or a solid depending on how much pressure was applied. The mixture is one of a few substances that has properties of both a liquid and a solid and is classified as a non-Newtonian fluid. Cornstarch and water is probably the most commonly found example of this. (It also is the inspiration for the Dr. Seuss book titled, Bartholomew and the Oobleck.)
