Kitchen counter science: soluble/insoluble

Water, water everywhere, and not a drop to drink. Especially this stuff. I wouldn't drink from a single one of these glasses.

This week finds us exploring mixtures and solutions. You know, the breaking down of a substance into its basic molecular form so it can "swim" among the liquid masses. Calvin got a real kick out of that visual. We had a good time creating a chart with columns for soluble, insoluble, and hypothesis, and I was thoroughly surprised by how often he was right on with his forecasting. He didn't know why he thought sugar would dissolve while flour would not, but he was right on pretty much across the board. Plus, it was great fun to design and create interesting concoctions in the kitchen.
