First graders have been studying the different states of matter in science (liquid, solid, & gas).

Last week first graders enjoyed the book Bartholomew and the Oobleck for Dr. Seuss’ birthday. They then headed over to the Lower School Science Lab to make their very own Oobleck for a fun cross-curricular activity.

The experiment asked students one simple question; what state of matter will we create when corn starch and water are mixed?

Student’s mixed their corn starch with water, and added green food coloring to match Dr. Seuss’s Oobleck. The mixture becomes what is known as a Non-Newtonian Fluid.  If you hit it, it acts as a solid. But if you hold it still, it acts as a liquid. It changes depending on the pressure, or force, exerted, rather than changing due to temperature.
