The document discusses the three states of matter - solid, liquid, and gas - and provides examples using water. It defines the key properties of each state, such as solids maintaining a fixed shape while liquids and gases take the shape of their container. Water is used as an example, describing how it can exist as a solid (ice), liquid (water), or gas (water vapor) and demonstrating the properties of each state. The document concludes by listing the relevant first grade physical science learning standards regarding states of matter and water.
