Year 6 Science

TERM I 2022/2023

Unit 6.1 Forces and movement, on Earth and beyond

In this unit learners will understand the difference between mass and weight, they will have opportunities to use the terms correctly. They will build on their knowledge of force diagrams and how to use them to show the forces acting on an object. They will also learn to describe, in detail, the forces acting on an object and how forces affect whether objects float or sink.

Unit 6.2 Human health and disease

In this unit learners will develop an understanding of two of the major body systems of humans, and most vertebrates; the respiratory system and the circulatory system. They will understand that these two systems are fundamental for human life and many of the processes of the human body.

TERM II 2022/2023

Unit 6.3 Materials, including rocks, and physical change

This unit covers a range of properties of materials and substances and how they change under specific conditions. Learners will continue to develop their understanding of the particle model in the context of boiling and evaporation; they will understand that different substances change state at different temperatures and that many physical changes of substances are reversible.

Unit 6.4 Electricity, conductors and light

In this unit learners will continue to develop their understanding about phenomena that are abstract and difficult to conceptualise.

Learners will consider aspects of electrical circuits: they need to be closed to work, they need an energy source and there are international conventions on how circuit diagrams are drawn. They will also learn the difference between series and parallel circuits

TERM III 2022/2023

Unit 6.5  Chemical changes and mixtures

In this unit learners will understand how chemical reactions result in the formation of new substances and how to recognise when a chemical reaction has occurred.

They will then consider mixtures including dissolving by investigating how dissolving is affected by temperature. Learners will then expand their understanding of mixtures to looking at soils which are different mixtures of many different substances

Unit 6.6 Ecosystems

In this unit, learners will extend their understanding of food chains into more complex food webs. They will explore different food webs that are found in different ecosystems and how each food web is made up of interacting food chains.
