4th-6th Makes Oobleck


Fourth through sixth grade students made oobleck in early March as part of a celebration of Dr. Seuss' birthday. Oobleck is a milky-white substance known as a non-Newtonian fluid. It flows like thick paint when you pour it but if you apply a force to it by smacking or squeezing it, this strange fluid becomes a solid.


Making oobleck is a great way for students to learn the different properties of solids, liquids, and gases because it doesn't follow the rules for fluids. Students know that solids have a definite shape whereas a fluid can change shapes as it flows. Ooblecks defies all of those rules!


Students dyed their oobleck green and had a blast playing with the slimy stuff as it switched back and forth from a solid to a liquid!
