KS3 Subject Intent

Our Science Department Vision:

To ensure that Science is recognised for its fundamental significance in everything, its influence on our history and its importance to all our futures. To nurture students who are scientifically literate, knowledgeable, and inquisitive. A sense of excitement and curiosity will be promoted through the use of current, relevant and real-world Science. Students are not only able to develop a good understanding of Scientific topics but will also be analytical and able to make intelligent and logical observations about the world around us.

As of Septmeber 2022 we are introducing our new “The Big Ideas” curriculum in both KS3 and KS4 Science. Students will be learning about the 15 Big Ideas of Science (5 Biology, 5 Chemistry and 5 Physics) through appropriately sequenced key concept topics, allowing learning progression in each of our Big Ideas. The sequencing of these topics is based on BEST research evidence on sequencing which will enable the best learning progression of students in Science.


The Cellular Basis of Life: Organisms are made of one or more cells, which need a supply of energy and molecules to carry out life processes.

Heredity And Life Cycles: Genetic Information is passed from each generation to the next; this information and the environment affect features, growth and development of organisms.

Organisms and their Environments: All organisms, including humans, depend on, interact with and affect the environments in which they live and other organisms that live there.

Variation, Adaptation, and Evolution: Difference between organisms cause the species to evolve by natural selection of better adapted individuals. The great diversity of organisms is the results of evolution.

Health and Disease: Organisms must stay in good health and thrive; the health of an individual results from interactions between its body, behaviour, environment and other organisms.


Substances and Properties: Materials are either made of a single chemical substance or a mixture of subsances which each have distinctive properties.

Particles and Structure: All matter is made up of atoms. The behaviour and structural arrangement of atoms explains the properties of different materials.

Chemical Reactions: During chemical reactions, atoms are rearranged and new substances are formed.

Earth Chemistry: Substances can move within and between the atmosphere, hydrosphere, geosphere and biosphere as part of large-scale Earth systems.

Dynamic Earth: The Earth’s crust is constantly changing as new rocks are formed and older rock is worn away.


Matter: Objects are made of Particles and Mass. Understanding Particles helps us to design our world.

Forces and Motion: Forces make things change. Understanding forces helps us to predict and control physicsl change.

Sound, Light and Waves: Waves radiate information. Understanding waves helps us to control physical change.

Electricity and Magnetism: The everyday world is largely a consequence of electrical charge. Understanding electricity and magnetism helps us develop technology to improve lives.

Earth and Space: Understanding the uniqueness of the Earth and the Vastness of space gives us perspective and awe.

In Years 7 and 8 the lessons taught will cover all of the KS3 National curriculum with Year 9 consolidating, developing and expanding upon this content whilst also introducing some of the fundamental content needed at GCSE.
