Introduction:
Water is all around us in one form or another. When you cool yourself off on a hot and humid afternoon with a tall glass of water loaded with ice, you’ve got the three states, or phases of water right there—liquid, solid, and gas.
In this lesson you will:
- Identify the three states, or phases, of matter: solid, liquid, and gas
- Explore how water changes from one phase to another
- Examine arrangement and movement of water molecules in each phase of matter
