Matter can be solid, liquid, or gas. Solids keep their shape, liquids flow and take a container’s shape, and gases spread to fill their container. A change of state happens when heating or cooling changes one state into another.
Spend 10 minutes comparing ice, liquid water, and air in a balloon, then record the melting change of state.

Check understanding
- Correctly sort a set of everyday materials as solid, liquid, or gas and give a reason for each
- Use the terms solid, liquid, and gas accurately when describing everyday substances
- Use 'change of state' to describe what happens when ice melts or water boils
“If you point to water, ice, and steam from a kettle, can your child correctly call each one a liquid, solid, or gas — and use those words naturally?”
