===Key Stage 2===

: [[Material|Materials]] can be [[solid]], [[liquid ]] or [[gas]].

: Heating can turn a [[solid ]] into a [[liquid and ]]. This is called [[melting]].: Heating can turn a [[liquid ]] to a [[gas]]. This is called [[evaporating]].: Cooling can turn a [[gas ]] into a [[liquid and ]]. This is called [[condensing]].: Cooling can turn a [[liquid ]] into [[solid]]. This is called [[freezing]].
