This week we have continued to learn about liquids and solids. We have learned that liquids change shape to be in whatever container they are in, and that they flow. We have learned that solids do not change shape, and do not flow. Today we looked at salt, which was a bit tricky because it looked like it flowed and changed shape when put in different containers, but then we looked at it with a microscope to see that there are actually many, many little grains that make up salt. We have decided that salt is a solid, because the grains do not flow or change shape.
