Solids, Liquids, and Gases

All things on Earth consist of matter, and matter exists in many forms. The most common states of matter are solids, liquids, and gases. This unit addresses how matter can change from one state to another. Matter in each state has identifiable properties. The unit also explains that when matter combines, a mixture may form. The components of that mixture may retain their individual properties when combined, or the mixture may have new properties. What allows us to have so many different things all around us is that matter can be found in various states, and it combines with other matter in many ways.
