Assessment criteria
Quick Revision Summary (Key Takeaway)
The WJEC Entry Level Award in Science Today (Entry 3) is a vocationally-related qualification that introduces students to fundamental scientific concepts through practical, real-world contexts. It covers key areas of biology, chemistry, and physics, focusing on developing basic scientific skills and understanding for everyday life.
Topic Overview
The WJEC Entry Level Award in Science Today (Entry 3) is designed for students who are beginning their journey in science. It provides a foundation in the three main sciences: biology, chemistry, and physics. The qualification focuses on practical skills and applying scientific ideas to everyday situations, making it ideal for learners who prefer hands-on, contextual learning. Topics include basic cell structure, the properties of materials, and simple forces and energy.
This qualification is part of the Foundations for Learning suite, which aims to develop essential knowledge and skills for further study or employment. It is assessed through a portfolio of evidence and a short external test, allowing students to demonstrate their understanding in a variety of ways. The course emphasises scientific literacy, such as reading data, conducting simple experiments, and understanding safety in the lab.
Studying Science Today helps students make sense of the world around them, from understanding why we wash our hands to how a torch works. It builds confidence in using scientific vocabulary and following procedures, which are transferable skills for many careers. The qualification also prepares students for progression to higher-level science courses, such as GCSE Combined Science, by establishing core concepts and practical techniques.

Assessment Guidance
Guidance for achieving higher grades
- 💡In assessments, always link your safety response to the exact situation described rather than offering vague statements.
- 💡Use the correct terminology such as 'hazard', 'risk', and 'control measure' to demonstrate your knowledge explicitly.
- 💡When explaining risk minimisation, state the action taken and the consequence it prevents to fully meet the marking criteria.
- 💡When answering scenario-based questions, always explicitly link the identified risk to a specific, relevant control measure; e.g., 'Acid spill – neutralise and use absorbent granules while wearing gloves and goggles.'
- 💡Use the correct technical vocabulary for safety equipment (e.g., 'laboratory coat' rather than 'jacket') and hazard symbols (e.g., 'toxic' not 'skull sign') to demonstrate knowledge to the assessor.
- 💡In assignments, include a simple risk assessment format showing you can evaluate the level of risk after controls are applied, not just list hazards.
- 💡When responding to scenario-based questions, structure your answer systematically: list hazards, state associated risks, then outline relevant control measures.
- 💡Use specific examples from familiar science equipment and substances to demonstrate applied knowledge, such as hot plates, scalpels, or cleaning agents.
- 💡In assignment evidence, include annotated diagrams or photographs of safety setups to visually convey understanding of risk minimisation.
- 💡Always use the correct scientific terminology, such as 'evaporation' not 'drying up', to show your understanding.
- 💡In practical questions, mention safety precautions (e.g., wearing goggles) and how to use equipment correctly.
- 💡Read the question carefully: if it asks for 'two reasons', give exactly two, not one or three.
Common Mistakes
Common errors to avoid in your coursework
- Confusing a hazard with a risk, or using the terms interchangeably.
- Providing generic safety advice (e.g., 'be careful') without linking to a specific hazard.
- Failing to state why a safety measure effectively reduces the risk, showing only a superficial understanding.
- Confusing ‘hazard’ (something with potential to cause harm) with ‘risk’ (the likelihood and severity of harm occurring); learners often use the terms interchangeably.
- Failing to recognise that personal behaviour (e.g., running, eating in the lab) constitutes a significant risk factor, not just equipment or substances.
- Assuming that safety equipment such as fume cupboards or fire extinguishers eliminates risk completely rather than reducing it to an acceptable level.
- Overlooking the need to report all accidents, incidents, and near misses, regardless of perceived severity.
- Confusing a hazard with a risk; a hazard is the source of harm, risk is the likelihood and severity of that harm occurring.
- Forgetting to mention specific control measures for hazards, instead giving vague or generalised answers like 'be careful'.
- Assuming that safety equipment alone eliminates all danger without understanding the need for proper usage and maintenance.
- Misconception: 'All metals are magnetic.' Correction: Only iron, nickel, and cobalt are magnetic; other metals like copper and aluminium are not.
- Misconception: 'Evaporation and boiling are the same.' Correction: Evaporation happens at any temperature from the surface, while boiling occurs at a specific temperature throughout the liquid.
- Misconception: 'Plants get their food from the soil.' Correction: Plants make their own food through photosynthesis using sunlight, water, and carbon dioxide; soil provides minerals and support.

Exam Question Types
How this topic typically appears in the exam
- 📋Multiple-choice questions: These test recall of key facts. Read all options carefully and eliminate obvious wrong answers.
- 📋Short-answer questions: Often ask for definitions or one-word answers. Be precise and use the correct scientific term.
- 📋Practical-based questions: These describe an experiment and ask about equipment, safety, or results. Think about the steps you would take and the observations you would make.
- 📋Data analysis questions: You may be given a table or graph and asked to describe trends or calculate values. Always include units and quote figures from the data.
Command Word Expectations (WJEC-CBAC)
What examiners look for when using specific command words in this specification
Give a detailed account of what something is or what happens. For example, 'Describe the difference between a plant and animal cell' – you must state the key features of each, not just name them.
Give reasons or causes for something. For example, 'Explain why ice melts when heated' – you must link the energy input to the breaking of bonds between particles.
Give a brief, factual answer without explanation. For example, 'State one hazard in the lab' – a simple answer like 'broken glass' is enough.

- 1.Step 1: Place a small amount of the food sample in a test tube.
- 2.Step 2: Add a few drops of iodine solution (which is orange-brown).
- 3.Step 3: Observe the colour change: if starch is present, the solution turns blue-black; if not, it stays orange-brown.
