GCSE The Sciences
Mae disgrifiadau'r TGAU yn Saesneg yn unig, gan eu bod wedi eu cymryd o fanyleb Saesneg CBAC.
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.

Sgiliau sy'n defnyddio Cysyllteiriau a chystrawen

Writing balanced evaluations of ethical and environmental issues
Analysing, interpreting and evaluating (AO3) is a quarter of the marks in every unit. Learners must write about ethical issues such as embryonic stem cells and genetic testing (pages 40 and 41) and the debate over crude oil (page 53), weighing evidence to reach a decision.
Llythrennedd: Cynllunio a threfnu ar gyfer gwahanol ddibenion, cynulleidfaoedd a chyd-destunau, Cysyllteiriau a chystrawen
Paratoi disgyblion
- Blwyddyn 7
- Pupils write a paragraph on whether more wind turbines should be built on the hills above Aberdare, giving one benefit, one drawback and a conclusion.
- Blwyddyn 8
- Pupils write a balanced answer on whether single-use plastic bottles should be banned, linking points with 'however', 'whereas' and 'therefore'.
- Blwyddyn 9
- Pupils write an extended answer on whether Wales should stop burning gas to generate electricity, with points for and against and a justified conclusion, then improve it against a mark scheme.

Da gwybod
- 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.
Cysylltiadau â TGAU eraill
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.
