specification overview
SQA National 5 Chemistry is the Scottish equivalent of GCSE-level Chemistry, covering three areas of study: Chemical Changes and Structure; Nature's Chemistry; and Chemistry in Society. It's assessed by one 2-hour externally-marked written question paper worth 80 marks (80% of the qualification) plus an Assignment worth 20 marks (20%), graded A-D or No Award.
subject content
1. Chemical Changes and Structure
Written exam + assignment- Rates of reaction; atomic structure and bonding
- Formulae, equation writing and reaction quantities
- Acids and bases
2. Nature's Chemistry
Written exam + assignment- Homologous series: alkanes, alkenes, cycloalkanes, alcohols, carboxylic acids
- Everyday consumer products (esters, fats, oils, proteins)
- Energy from fuels
3. Chemistry in Society
Written exam + assignment- Metals: extraction, reactivity, corrosion
- Plastics; fertilisers; nuclear chemistry
- Chemical analysis: general practical techniques
assessment structure
| Paper | What's assessed | Length | Marks | Weight | Question types |
|---|---|---|---|---|---|
| Written exam (Question paper) | All three areas | 2h | 80 | 80% | Section 1: 20 marks (objective/multiple-choice). Section 2: 60 marks (restricted-response and extended-response questions). |
| Assignment | Individual research on a chosen chemical topic | Coursework | 20 | 20% | Research report written under exam-style conditions; externally marked by SQA |
Single-tier, all students take the same exam. Grades A-D plus No Award. The Assignment is a piece of individual research done in class time.
assessment objectives
| AO | What it means | Overall |
|---|---|---|
| Breadth | Drawing on knowledge and skills from across the course. | |
| Challenge | Requiring greater depth or extension of knowledge and/or skills. | |
| Application | Applying knowledge and/or skills in practical or theoretical contexts, and communicating findings. |
key tips for success
Start the Assignment early
The Assignment is 20% and takes real time to research and write. Start scoping the topic in S4.
Master the 20-mark objective section
Section 1 of the exam is worth 20 marks of objective (multiple-choice) questions. Practise pace and accuracy, this is where marks are gained or lost quickly.
Learn the homologous series
Nature's Chemistry rewards knowing alkanes, alkenes, cycloalkanes, alcohols and carboxylic acids with naming, formulae and reactions.
Build a chemical formula bank
SQA rewards writing correct chemical formulae. Practise until automatic (common ions, radicals, and equation balancing).
Master extended-response structure
Section 2 of the exam includes extended-response questions. Structure with clear chemical reasoning, correct terminology and worked examples.
Use SQA past papers
SQA National 5 Chemistry past papers are on the SQA website. Do timed practice through S4.
