KS3 Science Syllabus KS3SCI


Our KS3 Science Syllabus organises the big ideas and topics of the programme of study into clear objectives. It outlines what your students need to know, what they must be able to apply and how to extend that knowledge where appropriate.

The syllabus is easy to use. Just like a specification, it lays out clearly the key requirements. It also covers all of the working scientifically objectives with teaching ideas that you can weave into your lessons. 

Whether you teach KS3 over two years (year 7 and year 8) or three years (year 7 to year 9), this new syllabus will give you the direction and framework that will help you make the most of KS3 and prepare students for the step up to KS4 and GCSE


AQA for GCSE Combined Science: Trilogy


Combined Science: Trilogy (8464)


We believe that science has something to offer every student. That’s why we have a suite of science qualifications for Key Stage 4 – to suit students of all abilities and all aspirations.

The subject content and required practicals in this specification are also in our GCSE Biology, Chemistry and Physics. So you have the flexibility to co-teach and to move your students between courses

GCSE Combined Science Trilogy is interesting and relevant to all types of students. We’ve ensured that:

  • The biology, chemistry and physics content is presented clearly, in a logical teaching order. We’ve also given teaching guidance and signposted opportunities for skills development throughout the specification
  • The subject content and required practicals are also in our biology, chemistry and physics GCSEs so you have the flexibility to co-teach or to move your students between courses
  • All our science qualifications provide opportunities for progression. Combined Science: Trilogy gives students the option to progress to A-levels in science or other subjects





There are six papers: two biology, two chemistry and two physics. Each of the papers will assess knowledge and understanding from distinct topic areas
