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.

Researching and evaluating scientific information and media claims
The qualification's construct includes researching, evaluating and using scientific information to make informed decisions (page 7). Learners must be aware of how media influence and trust shape public views of stem cells, and how the media affects understanding of lifestyle and disease (Section 4.5.1, page 45).
Llythrennedd: Strategaethau darllen, Deall, ymateb a dadansoddi
Paratoi disgyblion
- Blwyddyn 7
- Pupils read two short articles about a new 'superfood' and sort the claims into fact, theory or opinion.
- Blwyddyn 8
- Pupils research whether mobile phone signals are harmful using three sources, and rate each source for reliability with a reason.
- Blwyddyn 9
- Pupils compare a tabloid headline and the NHS summary of the same health story, and explain how the media coverage could shape what the public believes.

Using scientific vocabulary and terminology precisely
Learners must use scientific vocabulary, terminology and definitions, including the Appendix C terms such as validity, resolution, precision and systematic error, in all units and in Unit 7 (page 64). Topics add precise vocabulary, for example allele, homozygous, genotype and phenotype in inheritance (page 41).
Llythrennedd: Geirfa, sillafu, gramadeg, Strategaethau darllen, Deall, ymateb a dadansoddi
Paratoi disgyblion
- Blwyddyn 7
- Pupils split science words into parts, such as 'photo' and 'synthesis', and build a glossary page that they add to in every topic.
- Blwyddyn 8
- Pupils match definitions of independent variable, anomaly and precision to examples from their own practical results.
- Blwyddyn 9
- Pupils use genotype, phenotype, dominant and recessive correctly in a paragraph explaining a simple cross in pea plants, and spell each term from memory in a starter quiz.

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.
