The document discusses the three states of matter - solid, liquid, and gas. It defines each state and provides examples. Solids have a fixed shape and volume, with particles arranged tightly. Liquids have a fixed volume but no fixed shape, with particles moving past one another. Gases have no fixed shape or volume, and particles are far apart with empty space between them. Following the presentation, students will write a paragraph describing the three states and including an example of each state.
