Science at Key Stage 4

All students study Science at KS4.  In Year 9 and 10 they enjoy 9 hours of science per fortnight on the T pathway and 10 hours for both the P and S pathway. In Year 11 they have 9 hours per fortnight on the T pathway but 11 hours for both the P and S pathway in order to prepare them for their GCSE exams at the end of the year. This allows us to cover a broad curriculum of science skills and topics across the course being studied.

Students on the T pathway are eligible to be entered for Separate Science GCSEs in Year 11 often referred to as Triple Science. All T pathway classes learn the content for the Separate Science GCSEs and sit these GCSE paper 1’s as pre public examinations in December of Year 11. Based on their results from these internal exams, as well as their attitude to learning and other teacher assessments, students are entered for either Separate Sciences or for Combined Science at HT to allow them to attain the best possible outcome for them.

Students on the P pathway study the Combined Science HT content and similarly to those on the T pathway will sit pre public examinations in December of Year 11 and the results from these decide their entries for Combined Science whether HT or FT. Students on the S pathway study Combined Science FT content and sit pre public examinations for these in December of Year 11.

As a Science department we have high aspirations for all students to access and achieve the best possible outcomes for their development of scientific knowledge and understanding of the world in which they live.

AQA GCSE Separate Sciences (Triple Science)

Assessment

All GCSE science courses are now terminally assessed, meaning that no formal external exams are sat until the end of Year 11, in line with recent Government directives.  The Triple Science course is examined as follows:

Subject Paper 1 Paper 2
Biology Topics 1 – 4, 1 hour 45 minutes (100 marks) Topics 5 – 7 – 1 hour 45 minutes (100 marks)
Chemistry Topics 1 – 5, 1 hour 45 minutes (100 marks) Topics 6 – 10 – 1 hour 45 minutes (100 marks)
Physics Topics 1- 4, 1 hour 45 minutes (100 marks) Topics 5 – 8 – 1 hour 45 minutes (100 marks)

Each exam is worth 50% of that subjects GCSE qualification. Coursework is no longer part of the course and students complete required practical work throughout their lessons which they will be assessed on in their exams.

Students are monitored regularly via short tests and other assessed work to enable us to keep track of their progress.  Where progress appears to be at a lower level than we would expect, various intervention methods are then employed to boost attainment.

 

Outcomes

Students entered on the separate Science GCSEs will gain three separate GCSE grades, one in each of the three sciences.  The grades are completely independent from one another, meaning that three separate grades are possible, however through our intervention strategies; we aim for all students to achieve their target grade in all three Science GCSEs.

Careers

The Triple Science route is an excellent foundation for students wishing to progress into careers with a strong scientific focus.  Careers such as medicine, pharmacy, veterinary work and research are commonly pursued by ex-students.   If a scientific career is not something that students wish to follow, a sound scientific background is invaluable in many careers as scientists tend to possess a logical and methodical approach to any task they undertake.

AQA GCSE Combined Science (Trilogy)

Assessment

All GCSE science courses are now terminally assessed, meaning that no formal external exams are sat until the end of Year 11. The Combined Science course is examined as follows:

Subject Paper 1 Paper 2
Biology Topics 1 – 4, 1 hour 15 minutes (70 marks) Topics 5 – 7,  1 hour 15 minutes (70 marks)
Chemistry Topics 1 – 5, 1 hour 15 minutes (70 marks) Topics 6 – 10, 1 hour 15 minutes (70 marks)
Physics Topics 1 – 4, 1 hour 15 minutes (70 marks) Topics 5 – 7,  1 hour 15 minutes (70 marks)

Each exam is worth 16.7% of their two GCSE qualifications. Coursework is no longer part of the course and students complete required practical work throughout their lessons which they will be assessed on in their exams.

Students are monitored regularly via short tests and other assessed work to enable us to keep track of their progress.  Where progress appears to be at a lower level than we would expect, various intervention methods are then employed to boost attainment.

Outcomes

Students entered on the Combined Science AQA GCSE course will gain two GCSE grades.  We aim for all students to achieve their target grade in both Science GCSEs.

Careers

The combined science route is an excellent foundation for students wishing to progress into careers where science may be useful.  Careers in the scientific industry and research are commonly pursued by ex-students.  If a scientific career is not something that students wish to follow, a sound scientific background is invaluable in many careers as scientists tend to possess a logical and methodical approach to any task they undertake.
