Students learn about the properties of liquids and solids. When a liquid is poured into a container, it takes the shape of the part of the container that it occupies. Cooling a liquid can turn the liquid into a solid (e.g., water to ice). When it becomes a solid it assumes the shape of the container and retains that shape, even when removed from the container. These observations about the properties of materials and how numerous materials can change from liquid to solid and back again begin to build an understanding of matter and its transformations that will be formalized as states of matter during the grade 2-3 band.
