Level of teaching: Key Stage 3, Key Stage 4, Key Stage 5

The study of Chemistry encourages students to explore the nature of substances and how they react together. It engages learners at many levels, linking direct practical experience with scientific ideas. Experimentation and modelling are used to develop and evaluate explanations, encouraging critical and creative thought. Students learn how knowledge and understanding in Chemistry are rooted in evidence. They discover how scientific ideas contribute to technological change – affecting industry, business and medicine and improving quality of life. They trace the development of science worldwide and recognise its cultural significance. They learn to question and discuss issues that may affect their own lives, the directions of societies and the future of the world.

Key Stage 3 (Years 7-8)

In KS3 Science, we follow the AQA Activate Science Course. This involves learning about the ’10 Big Ideas’ science curriculum over a 2-year key stage. Each ‘Big Idea’ contain four smaller topics that build in complexity. Details are as follows:

Year 7

Part 1 – Taught in Year 7
Forces: Speed & Gravity
Electromagnets: Voltage and Resistance & Current
Energy: Energy costs & Energy transfer
Waves: Sound & Light
Matter: Particle model & Separating mixtures
Part 1 – Taught in Year 7
Reactions: Metals and non-metals & Acids and alkalis
Earth: Earth structure & Universe
Organisms: Movement & Cells
Ecosystems: Interdependence & Plant reproduction
Genes: Variation & Human reproduction

Year 8

Part 2 – Taught in Year 8
Forces: Contact forces & Pressure
Electromagnets: Electromagnets & Magnetism
Energy: Work & Heating and cooling
Waves: Wave effects & Wave properties
Matter: Periodic table & Elements
Part 2 – Taught in Year 8
Reactions: Chemical energy & Types of reaction
Earth: Climate & Earth resources
Organisms: Breathing & Digestion
Ecosystems: Respiration & Photosynthesis
Genes: Evolution & Inheritance


In KS3 Science, we rotate Biology, Chemistry and Physics topics through the year to complete all the outcomes within the ten big ideas topics. We follow the AQA Activate Science schemes of work, which provide students with opportunities for regular practical work, and development of their numeracy and literacy skills within Science. The progress of students is tracked regularly with end of unit assessments and formal end of year exams.

Key Stage 4 (Years 9-11)

Course Code: GCSE Chemistry AQA 8462
Exam Board Specification:

Course Code: GCSE Combined Science Trilogy AQA 8464
Exam Board Specification:

GCSE Chemistry gives students a good understanding of the nature of substances and how they react together, how chemistry is used in business and industry and how our use of fuels affect the local and global environment. It is a fascinating and engaging course which explores both the science of the building blocks of life and ethical issues surrounding developments in technology.  This course provides a firm foundation for progression to A Level Chemistry.

GCSE Chemistry is examined by 2 x 1hr 45min exams at the end of the course. It also involves a practical endorsement which doesn’t contribute to the overall grade.

Unit 1: Chemistry Paper 1 – Written paper 1 hr 45mins – 100 marks worth 50%
Unit 2: Chemistry Paper 2 – Written paper 1 hr 45mins – 100 marks worth 50%

Year 9

Students start GCSE in Year 9 and rotate classes so that students get a taste of all three GCSE sciences before making their option choices where they choose to do either Combined or Triple Science in Year 10. We therefore teach everyone the triple science curriculum for the initial topics during Year 9 for an easy transition into Year 10.

In Year 10, students will continue on the course that they have chosen within their options.

Year 10

  1. Atoms, bonding and moles
  2. Chemical reactions and energy changes

Year 11

  1. Rates, equilibrium and organic chemistry
  2. Analysis and the Earth’s resources

GCSE Combined Science Pathway:

The GCSE Combined Science topics covered will involve a subset of the content from the three separate sciences.

Key Stage 5 (Years 12-13)

Course Code: A Level Chemistry AQA 7405
Exam Board Specification:

Recommended Entry Requirements

  • Grade 6 GCSE Chemistry or Grade 6-6 GCSE Combined Science
  • Grade 6 Mathematics
  • Students who have studied Combined Science must complete additional preparatory work over the summer holidays.

Why Chemistry?
This exciting course attempts to answer the big question “What is the world made of?” and in the search for this answer you will be investigating how one substance can be changed drastically into another, through to researching a new wonder drug to save millions of lives.

The course covers a broad range of topics within Physical, Inorganic and Organic chemistry including atomic structures, thermodynamics, periodicity, transition metals, alkanes and DNA. Practicals include measuring energy changes, identifying different compounds, preparing organic solids and liquids and undertaking advanced chromatography.

The opportunities are endless!
