We took our learning to the kitchen. Our goal: experiment with water's solvent properties. We read about water being the universal solvent and wanted to give it a try.
The challenge was to find four things they wanted to try to dissolve in water. If the substance was dissolved completely, it was a solution (a special type of mixture). If the substance was not dissolved, it was simply a mixture.
Little Guy picked olive oil, pancake mix, maple syrup, and salt. Big Sister picked baby powder, corn syrup, corn flour, and powder dish washing detergent.
Here is a picture of their individual set up.
Above, Little Guy was adding oil to the water. He found his first mixture.
Big Sister started with the corn syrup. After a few stirs, it was a clear solution.
Baby powder was more of a mystery to us. It was chosen by Big Sister out of her own curiosity. She stirred for a while but it was not getting completely dissolved. After a few long tries, she declared it a mixture.
The pancake mix was a cloudy solution.
Corn flour didn't dissolve completely. It was declared a mixture.
Both kids got a chance to draw their findings, to add to their water folder.
Little Guy was very happy to clean the cups.
Here is a picture of their recordings.
