The melting temperature of a material is the temperature at which it changes from solid state to liquid state.

A solid has a fixed shape and volume but some solids can change shape when a force is applied.

A liquid can flow, has a fixed volume and takes the shape of the bottom of its container.

Temperature is measured in degrees Celsius (°C).

In a conclusion, scientists explain what the results show or mean.

In this Introduction to states of matter and changing states unit, pupils learn that some materials change state when they are heated or cooled. In the Properties, changes and separating materials unit, they will build on this knowledge to learn that dissolving, mixing and changes of state are reversible changes

In the Everyday materials unit, pupils learnt to compare and group together a variety of everyday materials on the basis of their simple physical properties. In this Introduction to states of matter and changing states unit, pupils will build on this knowledge to compare and group materials together according to whether they are solids, liquids or gases

This unit explores the properties of solids, liquids, and gases, and how materials change state when heated or cooled. It covers evaporation, condensation, and the water cycle, with a focus on practical enquiries, careful observations, accurate measurements, and presenting findings.
