Intent

The study of science ignites students’ curiosity about the natural world and the fundamental principles that govern it. Through the study of Biology, Chemistry and Physics, students develop an understanding of living organisms, matter, energy and the universe, while exploring how scientific discoveries continue to shape our lives and society.

Our curriculum places equal emphasis on developing scientific knowledge and understanding alongside the skills of scientific enquiry and investigation. Students learn how science works by asking questions, planning and carrying out investigations, analysing evidence, evaluating results and drawing informed conclusions. These essential scientific skills enable students to think critically, solve problems and make evidence-based decisions in an increasingly scientific and technological world.

The Science curriculum follows the National Curriculum throughout Key Stage 3 and the AQA specification at Key Stage 4. Knowledge and skills are carefully sequenced within a spiral curriculum, allowing students to revisit and build upon key concepts over time. This approach strengthens understanding, deepens knowledge and enables students to make meaningful links between topics across Biology, Chemistry and Physics.

Our aim is to inspire and motivate students to be inquisitive, resilient and confident scientists whilst providing appropriate support and challenge for every learner. We encourage students to question the world around them, evaluate scientific evidence from a range of sources and apply their knowledge to unfamiliar contexts. In an age where information is readily available but not always reliable, we believe the ability to think critically and evaluate evidence is an essential life skill. We strive to develop learners who can apply these scientific skills independently and confidently, both within the classroom and beyond, preparing them for success at Key Stage 4, Key Stage 5 and in their future lives.

Implementation

The Science curriculum is planned and sequenced to ensure that scientific study is accessible to all learners. Teachers plan individual lessons to meet the needs of their classes whilst following a carefully structured and collaboratively developed scheme of work. This provides a clear progression in both scientific knowledge and the application of key disciplinary skills, including planning investigations, analysing and evaluating data, drawing conclusions from evidence and applying scientific concepts to unfamiliar contexts. Through our spiral curriculum, students revisit and build upon key ideas across Biology, Chemistry and Physics throughout Key Stages 3 and 4, enabling them to deepen their understanding, make connections between topics and develop increasing confidence in the application of scientific knowledge. The curriculum follows the National Curriculum at Key Stage 3 and the AQA GCSE Combined and Triple Science specifications at Key Stage 4, ensuring students are well prepared for the next stage of their education and for life in an increasingly scientific and technological world.

The Science department delivers a broad and balanced curriculum encompassing Biology, Chemistry and Physics. At Key Stage 3, students study the fundamental concepts outlined in the National Curriculum, including cells and organisation, ecosystems, genetics and evolution, particles and matter, chemical reactions, the periodic table, forces, energy, electricity, waves and the Earth and the universe. These concepts are revisited and developed through our spiral curriculum before being studied in greater depth through the AQA GCSE specifications at Key Stage 4. Practical work and scientific enquiry are embedded throughout the curriculum, providing students with regular opportunities to develop investigative skills, work safely, analyse evidence and evaluate scientific methods.

We understand that our young people come to us with varied educational experiences and that some may have gaps in their scientific knowledge and practical skills. We therefore prioritise re-engaging students with science by creating a safe, supportive and ambitious learning environment where curiosity is encouraged, misconceptions are addressed and success is celebrated. Teaching is adapted to meet individual needs through appropriate scaffolding, targeted intervention and opportunities for stretch and challenge, ensuring that all students can access the curriculum, develop confidence as scientists and make sustained progress regardless of their starting point.
