Lesson Details
Key learning points
- There are lots of examples of solids and liquids changing state in real life.

Common misconception
Pupils may not have experience of a solid material changing to its liquid state then back to its solid state again.
Pupils will explore melting solid wax then watching it change back from a liquid to a solid again as it cools. The lesson provides many examples of where changing state is useful to humans in industry and every day life.
Keywords
Solid - A solid has a fixed shape and volume but some solids can change shape when a force is applied.
Changing state - Changing state is when a material changes state from one state to another.
Temperature - Temperature is a measure of how hot or cold something is.
Melting - Melting is when a material or substance changes from its solid state to its liquid state.
Liquid - A liquid can flow, has a fixed volume and takes the shape of the bottom of its container.
