A material is the substance that objects are made from such as wood, metal or plastic.

The physical properties of a material are the features that can be observed or measured.

A thermal insulator is a material that does not allow heat to pass through it easily.

In a comparative test, the variable that is being changed has names or labels, such as the names of plants.

A variable is something that can be changed, measured or kept the same in an investigation.

Science

In this Properties, changes and separating materials unit, pupils learn to decide how mixtures might be separated, including through filtering, sieving and evaporating. In the Materials challenge unit, they will build on this knowledge to apply their understanding of separating materials to a wider range of everyday situations

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 Properties, changes and separating materials, pupils will build on this knowledge to compare an group together everyday materials on the basis of a wider variety of properties
