![]() What happens when objects are dropped or placed in the oobleck? Try it! Is the evidence and data you are collecting helping you test your hypothesis question? Answers will vary based on the scientist. When you squeeze it, the cornstarch particles squish together making it feel solid. Is oobleck a liquid or a solid? It’s a Non-Newtonian fluid - a what? Check out the “How it Works” section for more information on what that is! During the Experiment What happens when you squeeze the oobleck in your hand? Try it! What happens to water if you do the same? Try it! What causes the oobleck to turn into a solid when pressure is added? Applying pressure increases its thickness, or its viscosity. Solids are rigid and have their own shape. Be careful not to get it in your eyes, and wash your hands after handling the Oobleck.ĭiscovery Questions Beginning the Experiment What is the difference between a solid and a liquid? Liquids move and flow and take the shape of their container. **Note: Oobleck is non-toxic, but use caution when doing any science activity. Pouring it down the drain, even with lots of extra water, can clog pipes. Important Cleanup Information: Pour the oobleck into a zip-top storage bag and throw it away in the garbage.Multiply the quantity of each ingredient by 10 or more and mix it up. Bonus: Use a large plastic bin or tub to make a big batch of Oobleck.Play! Experiment to see when it feels most solid (hint: try punching or pounding it) and when it feels most liquid (hint: try slowly sinking an open hand into it).If desired, mix in a few of drops of food coloring.(The consistency should be somewhere between a liquid and a solid-you should be able to grab a clump using pressure to keep it “solid”, but when you open your hand it should “melt” back out like a liquid.) If it is too liquidy, add more corn starch by spoonfuls. Put 1 cup of water in a bowl and gradually add the cornstarch to it.Ask student to create a testable question (a hypothesis).Įxample: Will objects sink or float in the oobleck?. ![]()
