As  we listened to "Bartholomew and the Oobleck" by Dr. Seuss, the first grade scientists started talking about whether the oobleck was solid or liquid (YES!!!!).

After the story, we had a chance to experiment with the REAL oobleck:)

We compared and contrasted the oobleck to water (liquid) and solid (play dough).

Here are our discovery:

When we tapped on the oobleck, it felt hard just like play dough.  Also, we could roll it to make a ball, which told us that it was solid.
When we put the oobleck into a cup, it lost its shape and filled the cup.  That told us that the oobleck was liquid!

After playing more with the oobleck...

Here are our findings:

The oobleck is liquid AND solid.
When we keep moving the oobleck (ex. rolling), it stays as solid.
When we do not move it, it looses its shape.

Everyone was begging me to post a recipe for the oobleck.
I have to warn you, it will leave a HUGE mess!  Sorry:(

Mix 2 parts of cornstarch with one part of water (ex. 1 cup of cornstarch with 1/2 cup of water).
If you want a colored oobleck, mix food coloring with water before you pour it in the cornstarch.
