Yeast is a type of fungus. It is a micro-organism used for making bread.

Fermentation happens when yeast takes in nutrients from food and releases carbon dioxide and alcohol.

In a conclusion, scientists explain what the results show or mean.

The evaluation of an investigation includes what went well, what could have been improved and whether the investigation question was answered.

Carl Linnaeus and classification

Discovering and naming new species

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

This unit covers the classification of living things, including micro-organisms, plants, and animals, based on observable characteristics. It explores reasons for classification and focuses on planning scientific enquiries, recording data, presenting findings, and evaluating scientific evidence.
