KS3 Overview

The KS3 programme is split over two years.

In Year 7, students focus on:

Term 1:   Living systems

  Particulate nature of matter

  Forces and motion

Term 2:   Diet and health

  Atoms, elements and compounds

  The Solar System and Space

Term 3:   Reproduction and growth

  Acids and alkalis

  Electricity and electro-magnetism

In Year 8, students focus on:

Term 1:   Photosynthesis, respiration and circulation

  Chemical reactions


Term 2:  Genetics and evolution

  Materials and everyday chemistry


Term 3:  Ecosystems

  The Earth and atmosphere

  Levers, moments and pressure

All topics are assessed through end of topic tests, assessed homework, and end of year examinations. 


KS4 Overview


The Department follows the AQA GCSE scheme of work. 

All students follow the dual science pathway, studying Core biology, chemistry and physics and Additional biology, chemistry and physics.  Some students will qualify to take the triple science pathway consisting of a further series of examinations in biology, chemistry and physics.

Controlled assessments (ISAs) are a key component of the Science GCSE.  To enable students to reach the highest standards, we start teaching the Unit 1 science pathway in Year 9, so giving three years for the programme to be completed. 

In Year 9 GCSE Science A is studied. 

This consists a 1-hour written examination in Biology, Chemistry and Physics making up 75% of the total mark, and a controlled assessment (ISA) examining practical skills and is worth 25% of the total mark.

Topics covered include:

Biology:  Keeping Healthy, how our bodies defend themselves against infectious diseases, nerves and hormones, the use and abuse of drugs, interdependence and adaptation, energy and biomass in food chains, waste materials from plants and animals, genetic variation and its control, and evolution.

Chemistry:  Fundamental ideas in chemistry, limestone and building materials, metals, crude oil and fuels, other useful substances from crude oil, plant oils and their uses, and changes in the earth and its atmosphere.

Physics:  Energy transfer and kinetic theory, energy and efficiency, usefulness of electrical appliances, methods used to generate electricity, and waves.  

In Year 10 and 11 GCSE Additional Science is studied. 

This consists a 1-hour written examination in Biology, Chemistry and Physics making up 75% of the total mark, and a controlled assessment (ISA) examining practical skills and is worth 25% of the total mark.

Topics covered include:

Biology: Cells and transport, tissues and organs, photosynthesis, organisms and their environment, proteins, respiration, cell division and inheritance, and speciation.

Chemistry: Structure and bonding, Properties and uses of substances, atomic structure, rates of reaction, exothermic and endothermic reactions, acids, bases and salts, and electrolysis.

Physics:  Forces and their effects, kinetic energy, currents in electrical circuits, mains electricity and electrical appliances, radioactive substances, and nuclear fission and fusion.  


KS5 Overview

The Department follows the OCR A-level scheme of work for Biology, Chemistry and Physics.  All three sciences  consist of six modules over two years. 

Biology:  Students start by developing their practical skills and then continue taking Foundations in Biology, Exchange and Transport, Biodiversity, Evolution and Disease, Communication, Homeostasis and Energy, Genetics, Evolution and Ecosystems. 

Chemistry:  The first module is Development of Practical Skills followed by Foundations in Chemistry, Periodic Table and Energy, Core Organic Chemistry, Physical Chemistry and Transition Elements, and finally Organic Chemistry and Analysis.

Physics:  Development of Practical Skills is the first module followed by Foundations of Physics, Forces and Motion, Electron, Waves and Photons, Newtonian World and Astrophysics, and Particle and Medical Physics. 

BTEC Science Overview

Along with the traditional A-Level subjects of Chemistry; Physics and Biology the Science Department offers Level 3 BTEC Applied Science. 

Students develop their practical skills by conducting experiments in biology, chemistry and physics.  

The academic content of the course is on par with the A-Level disciplines.  However, the students also cover vocational aspects associated with working within the Science Industry such as laboratory design and understanding the importance of Laboratory Information Management Systems. 

The whole course is assessed via coursework and students can either go on to A-Level Sciences next year or continue with additional modules either in Health Care Science; Engineering; Environmental Science or Forensics.  

Extra Curricular Opportunities

  • Trips include @Bristol, Slimbridge Wildfowl Trust and regular STEM events.

Next steps or Where the subject leads

Learning science develops key skills such as logical thinking, problem solving, organisation and time management.  To be very successful at science, a student needs to incorporate english and mathematics into all of their activities. 

Science is a core subject that all employers, Colleges and Universities look for.  Knowledge of science provides an understanding of how we live our lives, how things work, how the world around us works and what that means for the environment.   A qualification in science strengthens every CV.

There are many jobs in science, including forensics, astronomy, engineering, research scientist (biologist, chemist, physicist), pathologist, climate change analyst, agricultural scientist, food technologist,  sound engineer, hydrologist, geoscientist, materials scientist and environmental scientist.  A science qualification is a gateway into medicine, vetinary science, dentistry, paramedics, mid-wifery, nursing, animal nurse, occupational health, teaching and of direct application to construction, psychology and health, beauty and social care professionals.
