Evaporation is the change of state from a liquid to a gas.

Water is called water vapour when it is in the gas state.

The water cycle is the name of the journey water takes as it moves from the sea or land to the atmosphere and back again.

Condensation is the change of state from a gas to a liquid.

Precipitation is water, in the solid or liquid state, which falls from the atmosphere to Earth’s surface.

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.
