Christ42Subject introduction

Head of Department: Mr Amrit Aujla

The department has eight teaching staff and three technicians:

‘Good teaching and learning’ - that has been the Science department’s focus in the last 10 years. We have achieved this – reflected in our consistently high attainment in Double and Separate Award Science. We are continuing to attain our goal of ‘outstanding teaching and learning’.

We are the largest department in the School as Science is a CORE subject (with effectively 3 subjects combined – Biology, Chemistry and Physics). We have a Head of Department (overall responsibility) and now have heads of Biology, Chemistry and Physics. We have six experienced teachers (5 full time, 1 part time). We all have vast experience (and success) at delivering the GCSE Curriculum with three Biologists, two Chemists and one Physics specialist.

There are 7 large laboratories, which have Fume Cupboards and the standard equipment necessary for delivering Science to a GCSE Level, as a practical subject.

At Key Stage 3 we deliver Science with the support of the Activate scheme which is specifically designed to feed into the study of GCSEs with the AQA exam board. Students study 5 hours of Science over the fortnight and we aim to ensure that KS3 classes have a single teacher for science, where this is not possible students will have a maximum of two Science teachers.

Curriculum Intent

The study of KS3 and KS4 Science enables students to learn about the fundamental scientific concepts. Through this study we hope to give students the ability to explain the material world around them and a variety of natural phenomena. E.g. studying the states of matter allows students to understand why ice melts in drinks and also why the global ice caps may melt due to global warming.

Through studying the ‘working scientifically’ content students gain practical experience of learning science through investigation, using practical equipment and testing scientific ideas. This also develops their understanding that scientific theories can develop or change.


Key Stage 3

Students have access to the online Activate textbooks that correspond to their in class learning and we encourage the use of these for independent study. 

These are particularly useful in preparing for the assessments that take place once per term. Students will be assessed on the content that they have most recently covered as well as 'throwback content' to assess their retention of knowledge. 

Topics covered

Year 7:

  • Biology - Cells, Structure & Function of Body Systems, Reproduction
  • Chemistry - Particles and their behaviour, Elements, atoms and compounds, Reactions, Acids & Alkalis
  • Physics - Forces, Sound, Light, Space

Year 8:

  • Biology - Healthy & Lifestyle, Ecosystem Processes, Adaptation & Inheritance
  • Chemistry - The Periodic Table, Separation Techniques, Metals and Acids, The Earth
  • Physics - Electricity & magnetism, Energy, Motion & pressure

Year 9:

Due to the amount of hours allocated to Science in Y9, Y10 and Y11 we begin the study of the GCSE Science course in Y9 and at the end of Y9 students opt to continue with their study of Combined Science (old name - Double Science) or to take the Separate Science course (old name - Triple Science) which involves extra lessons of Science in Y10 and Y11.

Students are placed into sets for groups 1 and 2, the remaining 3 classes are mixed ability groups Y, Z and W. 

The content we cover in Year 9 is as follows:

  • Biology - Ecology, The digestive system, organising animals
  • Chemistry - Atomic structure, States of matter, Chemical analysis, The Earth's Atmosphere, The Earth's resources
  • Physics - Energy, Energy Resources, Molecules and matter

Key Stage 5 / Sixth Form - A Level

A Level Biology

To study A level Biology is to embark on a journey of discovery!! Students learn about the basics of life, of organs and organ systems that can determine health, or sickness and disease. Best of all, students look deeper into the nucleus of cells and discover the amazing molecule called DNA. It controls almost everything that makes you, you.

Students will study the principles of electron microscopy, ultrastructure of cells, biological molecules, enzyme technology, transport and exchange mechanisms in plants and animals, classification, diversity and speciation.

In the second year, biotechnology and genetic engineering are key features, and the range and limits of homeostatic control systems, nervous and hormonal coordination. Many physiological and biochemical processes including respiration and photosynthesis are also explored.  

Practical work is at the heart of biology and will be examined in the written exams. Field work is a compulsory element of the course, usually undertaken at Juniper Hall in Dorking.

AS: two written examinations each 1 hour and 30 minutes long. This is now a stand-alone qualification and will not contribute to A-level.

A-Level: three written examinations each 2 hours long, at end of two years.

There are 9 lessons over the two week timetable taught by 2 Biology specialist teachers.

A level Chemistry

Chemistry is about everything. It is the central science that explains how the world around us works.  It enables us to see patterns in the myriads of chemical reactions that occur in nature.  In this course students will see how the laws of chemistry and the skills of today’s chemists have been used to achieve our present high standards of living. AS Chemistry is an exciting course that places emphasis on the application of knowledge and the usefulness of laboratory research.

Progress will be checked via Independent Study packs and end of unit tests.

Students will study the basic laws and principles of chemistry and learn how to predict the properties and the atomic structure of elements from their positions in the periodic table. Topics will also include organic chemistry, carbon compounds including fossil fuels, plastics and recycling.  Students learn how to control chemical reactions and the importance of chemistry in manufacturing processes. Students are introduced to modern analytical techniques such as mass spectroscopy and nuclear magnetic resonance.

A-Level: three written examinations each 2 hours long, at end of two years.

There are 9 lessons over the two week timetable taught by 2 Chemistry specialist teachers.

Students’ practical skills will be developed throughout the course and assessed in the written examinations.

A level Physics

Physics is about how things work, from the nano-scale to the cosmic - super massive black holes and galaxies within the universe. Students will learn about forces in mechanics, waves, electrons and protons, gravitational, electrical and magnetic fields.  Students will investigate nuclear energy and apply the fundamental principles learnt to solve real problems.  Practical investigations will be conducted in the Physics laboratory in addition to learning theoretical Physics.

Progress is checked via homework and testing, each week.

Students are expected to bring together the principles and concepts from different areas of physics and apply them in a particular context which may be unfamiliar to them. High standards of work are essential. Students are expected to express their ideas clearly and logically using specialist vocabulary.

  • AS: two written examinations plus one practical examination.

  • A2: two written examinations plus practical based coursework

There are 9 lessons over the two week timetable taught by 2 Physics specialist teachers.

This course may provide opportunities for day trips and visit from external providers.


Recently the department held a successful ‘Science Week’ that involved all year groups, with our Year 12 and 13 students helping with the implementation and planning. This included a series of lessons that explored Forensic Science.

  • Science permeates through ALL aspects of our society, from the recycling bins that our department funded to the understanding of ‘reproduction’ – with social, moral and ethical issues. It would be impossible to list specific relevance as it is an ‘over-reaching’ subject

  • We have a KS3 Year 7 Science Club. This term the students have been designing and making models of Formula One cars.


Biology: The possibilities range from medicine to agriculture, forensics to zoology.  Almost any degree will accept A-level biology.

Chemistry: All manufacturing industries, pharmaceuticals, food processing, cosmetics and metal works.  Chemistry is essential for medicine, dentistry, chemical engineering and a whole host of health and environmental courses.

Physics: Essential for any engineering course or degree and is highly sought after for other scientific or technical careers. Physics is an advantageous subject for courses ranging from medicine to careers involving business and finance.
