Science

In this Why we group and classify living things unit, pupils learn about why we classify plants and animals based on specific characteristics. In the Species and classification unit, they will build on this knowledge to learn more about the identification and classification of organisms, including at the cellular level.

In the Living things and the environment unit, pupils learnt to recognise that living things can be grouped in a variety of ways. In this Why we group and classify living things unit, pupils will build on this knowledge to give reasons for classifying plants and animals based on specific characteristics
