We are grateful to have Dr. Marta Guron and the Chemisty Department from Villanova University present several lessons to our third graders. The students experimented with physical and chemical changes. Also, they got a chance to make oobleck.
Oobleck is a non-Newtonian fluid; it has properties of both liquids and solids. You can slowly dip your hand into it like a liquid, but if you squeeze the oobleck or punch it, it will feel solid. The name oobleck comes from the Dr. Seuss book, “Bartholomew and theOobleck.”
