Science
What is Science?
Science is a way of studying and understanding the universe in which we exist, which has been developed over time and in many cultures. We teach essential aspects of the knowledge, methods, processes and uses of science.
Why do we teach Science at HASU?
We seek to develop scientific knowledge and conceptual understanding through the specific disciplines of biology, chemistry, and physics. Science promotes an evidence-based approach to enquiry and pupils are encouraged to recognise the power of rational explanation. However, science is not to be seen as a static body of knowledge, rather as a dynamic and developing accumulation of human wisdom. Through their study of science, pupils are encouraged to test theories and look for alternative explanations. The scientific approach helps pupils to develop as independent and collaborative learners, respecting everyone’s contribution.
We are building links with the wider scientific community, especially in the field of medical sciences, given our location on the campus of the London Cancer Hub. Science is presented in the wider context of STEM subjects (science, technology, engineering and mathematics) with visits, presentations from visiting speakers, and enrichment activities. There is a strong focus on the many career pathways to which studying science can lead.
Above all, we are seeking to develop a sense of excitement and curiosity through an enquiring and investigative approach. We hope to kindle in our pupils the spirit of enquiry expressed by Albert Einstein, who said, "The important thing is not to stop questioning… (We) cannot help but be in awe when (we) contemplate the mysteries of eternity, of life, of the marvellous structure of reality."
How do we teach Science at HASU?
At Harris Academy Sutton, we offer a high-quality science education which provides the foundations for understanding the world through the specific disciplines of biology, chemistry, and physics. As well as developing our students’ knowledge and understanding of scientific theory through lessons in each of these three disciplines, our curriculum has an integrated working scientifically component and a clear focus on literacy and communication that seeks to develop students’ confidence in articulating their scientific ideas. The essential skills of enquiry processes are taught throughout the course and are developed further through a series of required practicals.
We are fortunate to enjoy state-of-the-art science facilities spread over two floors, including specialist biology, chemistry, and physics laboratories, and a ‘super-lab’ that can accommodate up to 60 students for lecture-demonstrations or large-scale practical activities. There is a strong emphasis on practical learning, ably supported by our team of dedicated science technicians.
Key Stage 3
At Key Stage 3, pupils have three lessons per fortnight in each of the specific disciplines of biology, chemistry, and physics. The common skills of working scientifically are incorporated into these lessons across the three disciplines. The taught content is divided into ten ‘big ideas’ of Science: Forces, Electromagnetism, Energy, Waves, Matter, Reactions, Earth, Organisms, Ecosystems and Genes. Each of these ‘big ideas’ is in turn divided into four smaller topics encountered at regular intervals so that students develop an understanding of a big idea by multiple interactions with the concepts within the idea.
Key Stage 4
All students at Harris Academy Sutton continue their study of science at GCSE as part of our broad and balanced Key Stage 4 curriculum. Science is a compulsory subject in the English curriculum at Key Stage 4. In other words, it is not an optional subject – everyone studies science in one form or another at this level.
Students in Years 10 and 11 at Harris Academy Sutton follow one of two courses of study: some study Biology, Chemistry and Physics as three full GCSEs (sometimes referred to as ‘separate sciences’ or ‘triple science’); others follow the Combined Science: Trilogy route, which is also taught through the three subject disciplines of biology, chemistry and physics, but results in students gaining two GCSE qualifications.
Whichever route students are following, their study of the Sciences at Key Stage 4 continues with the process of building upon and deepening scientific knowledge and the understanding of ideas developed in earlier key stages. As at Key Stage 3, this is done through the subject disciplines of biology, chemistry and physics, each now enjoying four lessons per fortnight. The knowledge and skills involved in scientific enquiry continue to weave their way through the whole specification.
Which examination board do we study at Key Stage 4?
Students studying the sciences at HASU follow the AQA Specifications.
These specifications can be found here:
AQA GCSE Combined Science: Trilogy (8464)
A-Level Biology
Studying A-level Biology develops critical thinking and scientific skills while exploring life at molecular, cellular, and ecological levels. Key topics include cell biology, genetics, biochemistry, physiology, evolution, and ecosystems. It prepares students for careers in medicine, research, and environmental science by linking theory to real-world applications.
The course follows the AQA Biology specification and is delivered by specialist teachers who integrate theory with practical application. A-level Biology practicals build essential scientific skills, including accurate measurement, data analysis, and experimental design. Students develop problem-solving, teamwork, and critical thinking while applying theory to real investigations. These hands-on experiences enhance understanding, prepare for university-level science, and foster confidence in conducting reliable, evidence-based research. Students are assessed on 12 required practicals in order to gain a practical endorsement certificate, which is in addition to their A-level.
There are 6 x 50 minute taught periods a week, with 4 hours of set homework. A-Level Biology students are encouraged to explore the subject beyond the specification to deepen their understanding and curiosity about the subject. Engaging with books, articles, podcasts, and current scientific developments helps students make connections between classroom learning and real-world applications. This wider reading not only strengthens their grasp of key concepts but also provides valuable material for UCAS personal statements, demonstrating genuine interest and independent learning. For students aiming for highly competitive courses such as those at Oxbridge, Russell group and other top universities, the ability to discuss ideas beyond the syllabus with insight and enthusiasm is often what distinguishes successful applicants
A-Level Chemistry
Is it possible to discover a cure for cancer? How can we prevent global warming? What innovative new materials might we develop in the future? If these world changing questions have you thinking, then Chemistry A-Level is the course for you. Chemistry A-Level is highly valued by admissions tutors at all Russell Group Universities and is the perfect qualification to enable you to study Science at degree level or move into many other professional fields. By studying chemistry, you will acquire a wide range of transferable skills and learn about ideas and concepts which address all the important questions in modern science.
The course follows the OCR Chemistry A specification and is delivered by specialist teachers who integrate theory with practical application. A Level Chemistry practicals build essential scientific skills, including accurate measurement, data analysis, and experimental design.

A-Level Physics
Physics is fundamental to understanding the natural world, from the motion of everyday objects to the complexities of quantum and nuclear phenomena. At HASU, the A-level Physics course is designed to foster curiosity, resilience, and analytical thinking. Students build on their GCSE foundations, beginning with familiar topics such as mechanics and electricity before progressing to more advanced areas including particle physics, fields, and thermal dynamics.
The course follows the OCR Physics A specification and is delivered by specialist teachers who integrate theory with practical application. Students complete 12 required practicals, which are assessed for skills such as precision, analysis, and evaluation. In addition to these, many more teacher-led demonstrations and experimental activities are used to reinforce concepts and bring abstract ideas to life.
Practical work is not just a component of the course—it is central to the learning experience. While the practical endorsement does not contribute directly to the final grade, examination questions assess understanding of experimental techniques and outcomes. This approach ensures students develop a deep conceptual understanding alongside the skills needed for further study in physics, engineering, or other STEM fields.
There are 6 x 50 minute taught periods a week, with 4 hours of set homework. A Level Physics students are encouraged to read widely beyond the specification to deepen their understanding and curiosity about the subject. Engaging with books, articles, podcasts, and current scientific developments helps students make connections between classroom learning and real-world applications.
