PD Day: time to get messy!

One of our activities today was experimenting with cornstarch. First, we put our hands in dry, so feel the substance in it's powdered state. Next, we added water and let the kids mix it with their fingers. They liked that. :)

Then it was time to dig in! The harder they pushed, it seemed the mixture squeezed back! Then, when they held a clump of it still in their hands, it melted back into goop!

At nap time, I'm going to show the kids a short myth busters clip which has a great visual explanation of the molecular action of this super cool matter.

Later, we'll be back out into the snow! Thank goodness it snowed so much last night! Perfect day for snow play!
