1. Solids, Liquids and Gases By Kathleen Amy

2. Solids One of the major states of matter A solid does not take the shape of its container Atoms in a solid are tightly bound together

3. Liquids Second major state of matter Liquids can flow Liquids take the shape of their container Atoms in a liquid are loosely bound.
