Therefore, struggling in quicksand makes it harder to escape, but if you move slowly, you can get out. The “quicksand” you’ve created has a different viscosity depending on how much pressure you apply. The water and the pudding have different viscosities. Think about stirring a cup of water versus a cup of pudding. Viscosity corresponds to the concept of thickness. Unlike a solid or a liquid, non-Newtonian fluids have a different viscosity depending on the pressure you use. The quicksand-like material you have created is known as a non-Newtonian fluid. Now, imagine that you’re stuck in quicksand! If you struggle to escape, it will harden around your hands, but if you try to slide your hands back out slowly, you can escape. However, if they push their hand into the quicksand slowly, it will slide right in. Have your students tap the top of your “quicksand.” It should feel thick and hard. You’ll know it’s ready when it becomes difficult to stir quickly! Keep adding water until it starts to look thick like quicksand. Next, start pouring in the water and any food coloring you want to use. The cornstarch is a solid made up of tiny particles.
Science Experiment #1: Escape the Quicksand National STEM/STEAM Day, observed on November 8, is an opportunity to focus on science, technology, engineering, art, and mathematics topics and spark students’ interest in the STEM/STEAM fields.Ĭheck out these simple science experiments, perfect for introducing your students to what STEM is all about and sparking their curiosity! The best part is these experiments are parent-approved, and could make or some fun at-home activities, too.
Young learners have an innate curiosity to explore, build, and invent. Science is cool! If you have any doubts, keep reading.
