In Science the children explored the three states of matter - solids, liquids and gases. They talked about how matter can be mixed like a tossed salad. Then, the class explored what mixes with water. Adding water to separate cups containing olive oil, a saltine cracker, oatmeal, iced tea mix, sand and Cheerios, they were shaken and observed. A few minutes later they were observed again. The children found that some substances mix with water, some do not mix, and some initially mix but then settle to the bottom.
