Today both the Centipede and the Beetle classes explored the properties of Oobleck! Corn starch, like vinegar and baking soda, is a product that can be easily found in most kitchens.
By adding a little water to the corn starch powder, we created a fun sensory experience. First we explored this new medium with our hands and talked about how the mixture felt and what it did when we manipulated it.
Hey, it's soft AND hard!
Look what happens when we pick it up? It runs through our fingers.
This is kind of what hot lava would feel like if it was cool enough to touch.
I can make a rock. See?
I am making a big mess.
This is fun.
We also used small cups to try scooping and dumping the oobleck. It wasn't easy to put the oobleck into the cup because it was hard and clumpy. It poured out slowly when we tipped our cups over.
Is this a solid or a liquid?
It was fun to get messy.
Really, really messy!
When we were all done we watched it all wash away with the water. Science with toddlers and preschoolers doesn't need to be complicated, just interesting, fun, and usually messy too.
