GCSE Integrated Science
Integrated Science (Single Award) asks learners to read a pre-release Resource Folder worth a third of the Unit 1 paper, judge how reliable health and climate information is, write balanced evaluations, and write up a scientific enquiry alone under high control using precise scientific terms. Its numeracy load is heavy: Appendix D lists units, percentages, significant figures, substituting into equations, plotting graphs and, at higher tier, standard form, rearranging equations and gradients, all applied to energy costs, efficiency, density, motion and practical data. The single biggest thing Key Stage 3 should build is routine, confident handling of practical data: measuring with units, calculating means and values from equations, and plotting and explaining graphs.

Skills that use Understanding, response and analysis

Reading and using the pre-release Resource Folder
A third of the Unit 1 paper (24 of 72 marks) is based on a Resource Folder released one month before the examination. Learners must study unseen scientific texts and data in advance and answer questions on them using a clean copy in the examination.
Literacy: Reading strategies, Understanding, response and analysis
Getting pupils ready
- Year 7
- A week before the end of the healthy living topic, pupils get a one-page leaflet on energy drinks, highlight key words and write three questions they think a test could ask about it.
- Year 8
- Pupils receive a two-page pack on air quality in the Cynon Valley a lesson ahead, annotate the text and graph, then answer unseen questions on it in a timed lesson.
- Year 9
- Pupils work through a mock pre-release folder on electric vehicles over two weeks, building a glossary and a one-line summary of each source, then answer a short question paper using a clean copy.

“72 marks (24 marks will be allocated to questions linked to the pre-release material)”
Progression step 3
I can use a range of strategies for finding information, e.g. skimming for gist, scanning for detail.
I can read closely, identifying and noting features of texts, e.g. introduction, sequence, illustrations, formality, key vocabulary.
I can make use of reference/digital sources to select, summarise and synthesise information, referencing as appropriate.
Progression step 4
I can read, with concentration, printed and digital texts that are new to me and update, broaden and deepen my understanding of information, ideas and issues.
I can use a range of strategies, e.g. speed reading, close reading, annotation, prediction, to skim texts for gist, key ideas and themes, and scan for detailed information.
I can summarise, synthesise and analyse information to gain in-depth understanding, e.g. of causes, consequences, patterns, using different sources.
Progression step 5
I can read and analyse a range of unseen, printed and digital texts with concentration and independence.
I can use a range of strategies, e.g. speed reading, close reading, annotation, prediction, to skim texts for gist, key ideas and themes, and scan for detailed information, extracting and commenting maturely on key ideas and themes.
I can read closely, analysing the content, language and impact of texts to deepen my understanding.

Judging reliable sources of health and climate information
Learners must understand why reliable sources matter when making health decisions, such as on vaccination. In Unit 2 they must recognise that climate change is often over-simplified, with opinions based on only part of the evidence (Section 2.1.2, page 26).
Literacy: Reading strategies, Understanding, response and analysis
Getting pupils ready
- Year 7
- Pupils sort ten statements about germs and vaccines into fact, theory or opinion, and say where each one came from.
- Year 8
- Pupils compare an NHS Wales web page and a social media post about sugar in fizzy drinks, and list three reasons why one is more reliable than the other.
- Year 9
- Pupils read two news reports of the same climate study, pick out where each one over-simplifies the evidence, and rate each for reliability with reasons.

“that staying informed of health risks from reliable sources is crucial for making informed decisions about health and well-being”
Progression step 3
I can use inference and deduction to understand the text, and can consider the reliability of what I read.
I can distinguish between facts, theories and opinions.
Progression step 4
I can distinguish between facts/evidence and bias/arguments.
I can evaluate the usefulness and reliability of texts.
I can use inference and deduction to understand more complex texts, and can consider the reliability and impact of what I read.
Progression step 5
I can understand and explore in detail how texts may be interpreted, distinguishing between facts/evidence and bias/arguments.
I can use printed and digital texts to search selectively, assessing the reliability, significance and accuracy of what I find.
I can confidently evaluate the purpose, impact and reliability of texts.
Good to know
- Unit 1 includes a pre-release Resource Folder released one month before the examination: '24 marks will be allocated to questions linked to the pre-release material', and candidates receive a clean copy of the folder with the question paper (page 11).
- Unit 3 Task 2 (22 marks) is written alone: 'Learners must work independently in high controlled conditions' (page 33). In Task 1 (6 marks) learners 'may work in groups of no more than three' (page 33).
- Higher tier only mathematics is shown in bold in Appendix D (page 46): standard form, changing the subject of an equation, and determining and interpreting the gradient, slope and intercept of a linear graph. Calculating acceleration from the gradient of a speed-time graph (page 13) and calculating rate from a straight line (page 20) 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 44).
- AO3, 'Analyse, interpret and evaluate scientific information, processes, techniques and procedures', carries 25% of the qualification (page 35).
- The specification awards no separate marks for spelling, punctuation and grammar and makes no statement about calculator use.
