Learners mix liquid water with solid cornstarch. They investigate the slime produced, which has properties of both a solid and a liquid. When they press hard on the starch slime with their fingers, the slime acts like a solid. Starch in water is a suspension of solid particles in water. When learners leave the starch slime alone, it flows like a liquid. A great opportunity to discuss states of matter. This activity is currently used in the Nature of Matter Unit in OMSI's Chemistry Lab. Cost estimates are per 100 learners.
