GCSE The Sciences
The Sciences (Double Award) asks learners to research and evaluate scientific information, including how the media shapes public views, to write balanced answers on ethical and environmental issues, and to write up two scientific enquiries alone under high control using precise terminology. Its numeracy demand is high across six examinations and Unit 7: equations with SI units, chemical calculations, percentages, significant figures, graphs and gradients, sampling, probability in genetics and decay, and payback costs, with standard form, rearranging equations and y = mx + c at higher tier. The single biggest thing Key Stage 3 should build is fluent, well set out calculation from practical data: correct units, substitution into equations, means and graphs, explained in precise scientific language.

Skills that use Collecting data
-
Collecting data by sampling and experiment
Learners use ecological sampling to monitor species abundance and distribution, and must know when sampling techniques make samples representative (Appendix B, page 74). In each Unit 7 Task 1 they collect reliable data in groups of no more than three (page 64).
Numeracy: Collecting data, Strategic competence
Getting pupils ready
- Year 7
- Pupils place quadrats in ten random spots on the school field, count the daisies and record the counts in a tally table.
- Year 8
- Pupils compare plant numbers in sunny and shaded areas using quadrats along a tape measure, and decide how many samples they need for a fair comparison.
- Year 9
- Pupils test a hypothesis about lichen on trees near and far from a busy road, choosing random sampling points and recording both counts and descriptions.

Progression step 3
I can collect relevant data to answer posed questions.
I can identify, measure or obtain required information to complete the task.
Progression step 4
I can plan how to collect data to test a simple hypotheses.
I can collect both quantitative and qualitative data.
Progression step 5
I can collect data in a suitable way according to my hypothesis.
I can identify, measure or obtain required information to complete the task.
Good to know
- Unit 7 has two enquiries. In each, Task 2 (22 marks) is written alone: 'Learners must work independently in high controlled conditions'. In Task 1 (6 marks) 'Learners may work in groups of no more than three' (page 64).
- Exam aids are provided: 'Unit 3 and Unit 6 will include equations on page 2 of the examination question paper', and Units 2 and 5 include a periodic table on the final page (page 66).
- Higher tier only mathematics is shown in bold in Appendix D (page 78): standard form, changing the subject of an equation, y = mx + c, and the gradient, slope and intercept of a linear graph. Converting grams to moles (page 22), calculating rate from a straight line (page 25), acceleration from the gradient of a speed-time graph (page 30) and reacting masses (page 52) are also higher tier content.
- The uncertainty formula is provided: 'There is a formula to calculate this which you will be given in an exam' (Appendix C, page 76).
- AO3, 'Analyse, interpret and evaluate scientific information, processes, techniques and procedures', carries 25% of the marks in each unit (page 66).
- The specification awards no separate marks for spelling, punctuation and grammar and makes no statement about calculator use.
Links with other qualifications
The Appendix D mathematics overlaps closely with GCSE Mathematics and Numeracy, the scientific enquiry demands match GCSE Integrated Science, and the climate and sampling work overlaps with Geography.
