To evaporate is to change from a liquid to a gas.

Temperature is a measure of how hot or cold something is.

To affect something is to influence or change it.

Variables are the things that can be changed, measured or kept the same in a comparative or fair test.

Temperature and evaporation: plan

Science

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
