This is an activity that can be used with a unit on the Layers of the Earth or Plate Tectonics. It demonstrates how some matter can act like both a liquid and a solid called non-Newtonian fluid. It uses water and cornstarch. I have to play around with the ratio of cornstarch to water to get the right consistency. You want it to be thick but smooth with the cornstarch well mixed. I have put this activity lab in their Interactive Notebooks. The Power Point Slide is used with an Interactive Notebook. The left side is for the in and out question ( I call mine the K.O. short for Kick Off and G.O. for Get Out question.) the right side is where the activity, lab, or class notes go.
