Lab+Description

Lesson 1: ** Lab Activity:   ** ** Do the lab activity with cornstarch and water outlined on the very first page of the section **. ** Discuss the results with someone in your family. **   ** Answers and Discussion: ** If mixed carefully according to the instructions, the mixture forms a sort of semi-solid material. It will lay in the bowl like a liquid, until you attempt to jab at it or pick it up. Then it sort of “scrunches up” like a solid mass. It will resist jabbing like a solid but will act like a liquid if you slowly push your finger into it. If you form balls and then squeeze and release them, they will start to flow just like a liquid. The factor that determines if the mixture behaves as a solid or liquid seems to be how quickly you stress it.
