Plastic is a material which is made from oil and can be moulded.

If something is degradable, it can be broken down into the simple parts that made it.

A bioplastic is a plastic made from materials which come from sustainable sources such as plants.

To observe is to look very closely and use other senses too.

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
