Ewwww......!! Oobleck!!


1DS experimented recently with a substance called 'oobleck'.  Our inquiry question:  "Is this substance a solor or a liquid?"  We had a lot of fun trying to figure it out because oobleck seems to have properties of both!  














The Science Behind It:
Cornstarch is made up of long chains of atoms.  When you move them slowly past one another, they flow like a liquid because they can slide easily past each other.  When you squeeze, roll, or agitate them, the “atom chains” will get entangled and form a solid!  Substances like oobleck are referred to as “non-Newtonian fluids” because they do not have the normal properties of either solids or liquids.
