This unit provides students with basic understanding of what matter is and how different states of matter interact with one another. Students use concepts of mass, volume, and density to understand natural cycles of states of matter as well as buoyancy. UNDERSTANDINGS: 1. Matter is neither created nor destroyed, but can change states. 2. State of matter is dependent on energy and density of particles. 3. Changes in states of matter causes natural continuous cycles on Earth. (water cycle, rock cycle, convection weather patterns)
