Abstract
In this project you'll make a liquid that will contradict your expectations. Hold it loosely in your hand and it will drip off your fingers, but grab it tightly and it will feel solid. Slap a bowl of it with a spoon, and instead of splattering, it solidifies. Do background research on colloids, and be sure you can explain the following terms: colloid, Newtonian fluid, non-Newtonian fluid, thixotropic. (For instructions on how to make it see the link listed under Exploratorium, 1998, in the Resources section, below.) What happens if you put it on a flat surface? Does ooze leak through a small hole in a piece of paper? Are there other examples of non-Newtownian fluids? What do they have in common? How does "ooze" differ from a solution, such as sugar in water? (Exploratorium, 1998; Gardner, 1999, 30)Bibliography
