Ahhh summer. Warm sunny days, swimming, lightning bugs and dinners on the grill. A slower pace mandated by the heat and lack of scheduled activities. But what DO you do when the kids get bored?
Cornstarch putty! Part science, part art and part “playing with your food.” A grand slam of fun for all ages. Don’t believe me? Try it when everyone is home and watch as they can’t resist playing with it.
I used this activity as a science lesson for my son and had him compare the properties of the cornstarch and water before and after mixing it together. We talked about states of matter, whether mixing the two caused any physical and chemical changes, and the impact of force and how the mixture reacted.
Then we got out the food coloring and we played with mixing to experiment with color.
Hint: don’t use your hands to mix after adding food coloring as it will transfer color to your hands.
We did this activity in a clear pyrex pie plate so we could see what it looked like from underneath as well.
Here’s a link to instructions for this science activity from the University of Wisconsin:
