I love including my children in cooking, but it's not always possible--especially when sharp knives and hot pots are involved. So I've been building an arsenal of activities to keep them occupied and entertained while I tackle garlic chopping or lasagna assembling. For this experiment and sensory activity, we used flour, kitchen utensils, and colored chalk.
I filled a large bowl with a few scoops of flour and my kids got busy sifting, scooping, and mixing it. Meanwhile, I assembled dinner and got it in the oven.
Then, I grated some chalk into the bowl. My kids were intrigued and wanted to see what happened when it mixed with the flour. They were surprised that it mostly blended in, barely tinting the flour, and requested more!
While she stirred, I got some dishes done, and then I returned to grate some more chalk until she had enough. She learned about scale and volume while experimenting with these fun powdery substances, while I was able to make a hot meal--mostly uninterrupted!
