Exam board and Specification

AQA GCSE Combined Trilogy 
Specification code: 8464

The qualification covers the three science disciplines and is examined with 6 end of course papers each 1.5 hours long. Scores are combined and graded from 99-44 (Higher tier) and 55-11 (Foundation tier). Throughout the course, 18 practical investigations need to be completed. These are not formally written up and assessed as in previous specs but the skills developed are tested with the terminal papers

Year 9 Science

At St Peters we start their GCSE journey in year 9.

The following topics are Taught in 6 teaching cycles across the year.

Chemistry of the Atmosphere and using resources, Motion, Cells Structure and Division, Chemical Analysis, Waves and Magnetism.

These topics have been carefully selected to give year 9 pupils the best possible start to their GCSE studies and prepare to continue in years 10 and 11.

GCSE- Mathematical Skills

To promote ideas of disciplinary knowledge we have divided the lessons in to 3 for each specialism, and the using a tenth lesson to reinforce and support skills in developing knowledge in three categories:

  • Knowledge of methods that scientists use to answer questions-
  • the knowledge of apparatus and techniques-
  • Knowledge of data analysis skills.

For these sections we are using the required practical tasks as the focus to reinforce the ideas of techniques and practical work. Revisiting the skills for each of the practical’s. These are linked with the maths skills in sessions to develop the numeracy skills linked with the practical skills to interpret the data collected by each type.

The curriculum has been designed to map these skills against an appropriate sequence of the practical’s in line with the numerical skills associated with them.
