England
Key Stage 2
Programme of study: Science
Sc3 Materials and their properties; Changing materials
- 2b: to describe changes that occur when materials are heated or cooled
- 2d: about reversible changes, including melting, boiling, condensing, freezing and evaporating
- 2f: that non-reversible changes result in the formation of new materials that may be useful
Sc3 Materials and their properties; Separating mixtures of materials
- 3b: that some solids dissolve in water to give solutions but some do not
- 3c: how to separate insoluble solids from liquids by filtering
- 3d: how to recover dissolved solids by evaporating the liquid from the solution
QCA scheme of work primary science units 6C: More about dissolving and 6D: Reversible and irreversible changes
Wales
Key Stage 2
Programme of study: Science
Materials and their properties; Changing materials
- 2.1: to explore changes in materials and recognise those that can be reversed and those that cannot
- 2.2: that dissolving, melting, condensing, freezing and evaporating are changes that can be reversed
- 2.3: that irreversible changes result in a new material being produced, which may be useful
- 2.6: that heating or cooling materials can cause them to change
Materials and their properties; Separating mixtures of materials
- 3.2: that some solids are soluble in water and will dissolve to give solutions, but some will not
- 3.3: that insoluble solids can be separated from liquids by filtering
- 3.4: that solids that have dissolved can be recovered by evaporating the liquid from the solution
Northern Ireland
Key Stage 2
Programme of study: Science and technology
Materials; Change
- a: investigate which everyday substances dissolve in water
- c: investigate the changes of state brought about by heating and cooling everyday substances
- e: understand that when new materials are formed, change is permanent
Scotland
Environmental studies: 5-14 National guidelines
Science; Earth and space; Changing materials
- Level B: describe how everyday materials can be changed by heating or cooling
- Level B: give examples of everyday materials that dissolve in water
- Level C: distinguish between soluble and insoluble materials
- Level D: explain how evaporation and filtration can be used in the separation of solids from liquids
