Science: Health and Safety
This subtopic focuses on essential health and safety knowledge for a science setting at Entry Level 2. Learners will identify common hazards, such as chemicals, sharp objects, and electrical equipment, and understand basic safe working practices like wearing personal protective equipment (PPE) and following instructions. Practical application includes recognizing fire safety signs, knowing evacuation procedures, and selecting appropriate fire extinguishers to prevent accidents and ensure personal welfare.
Assessment criteria
Quick Revision Summary (Key Takeaway)
The WJEC Entry Level Certificate in Science Today (Entry 3) is a vocationally-related qualification that introduces students to fundamental scientific concepts through practical, real-world contexts. It covers biology, chemistry, and physics, focusing on developing basic scientific skills and understanding, with assessment through internal tasks and external exams.
Topic Overview
The WJEC Entry Level Certificate in Science Today (Entry 3) is designed for students who are building foundational knowledge in science. It covers key ideas from biology, chemistry, and physics, but always in the context of everyday life and vocational settings. For example, you might learn about the human body in relation to health and fitness, or about materials in the context of recycling. This makes the subject relevant and engaging, helping you see how science affects your world.
The qualification is assessed through a combination of internal tasks (such as practical investigations and written assignments) and external exams. You will be expected to demonstrate basic scientific skills like making observations, recording data, and drawing simple conclusions. The emphasis is on understanding and applying ideas rather than memorising complex facts. This course is an excellent stepping stone to further study, such as GCSE Combined Science or vocational qualifications in health, engineering, or agriculture.
In the wider curriculum, this qualification supports the development of numeracy, literacy, and problem-solving skills. It also encourages you to think about the impact of science on society, such as environmental issues and advances in medicine. By the end of the course, you should feel more confident in asking scientific questions and exploring the world around you.
Key Concepts
Core ideas you must understand for this topic
- →Living things: characteristics of life, basic needs, and simple classification.
- →Materials: properties of solids, liquids, and gases; changes of state; and simple chemical reactions.
- →Forces and energy: types of forces, simple machines, and energy sources.
- →Scientific method: making observations, predicting, measuring, and concluding.
- →Health and safety: using equipment correctly and assessing risks in practical work.
Learning Objectives
What you need to know and understand
- Know about different types of hazards, Know how to work safely in a workplace, Know about fire safety
Assessment Criteria
Key criteria assessors look for in your portfolio
- Award credit for correctly identifying at least two different types of hazards with relevant examples (e.g., chemical spill, sharp edge).
- Award credit for describing or selecting appropriate safety precautions for given scenarios, such as wearing goggles or washing hands.
- Award credit for demonstrating understanding of fire safety actions, including raising the alarm, following evacuation routes, or choosing the correct extinguisher type.
Assessment Guidance
Guidance for achieving higher grades
- 💡Always look for hazard symbols on containers and equipment before starting any activity—this will guide your safe actions.
- 💡Remember to match the correct PPE to the task, such as aprons for messy work or gloves for handling materials, as shown in visual prompts.
- 💡In an emergency assessment, describe the full fire safety routine: raise alarm, exit building via nearest safe route, and go to assembly point, without stopping for personal items.
- 💡Always read the question carefully and highlight key words like 'describe', 'explain', or 'state'. This tells you how much detail is needed.
- 💡In practical questions, use the data you have collected to support your conclusions. Refer to specific numbers or trends.
- 💡Show your working in calculations, even if it is simple. You can gain marks for correct steps even if the final answer is wrong.
Common Mistakes
Common errors to avoid in your coursework
- Confusing the 'fire exit' sign with a 'no entry' sign, leading to hesitation during an evacuation.
- Believing that water can be used on all types of fires, including electrical or chemical fires.
- Failing to recognise that loose clothing or long hair can be a hazard when working near flames or machinery.
- Misconception: 'Mass and weight are the same thing.' Correction: Mass is the amount of matter in an object (measured in kg), while weight is the force of gravity on that mass (measured in N).
- Misconception: 'All metals are magnetic.' Correction: Only iron, nickel, and cobalt are magnetic; other metals like copper and aluminium are not.
- 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.
Revision Plan
How to revise this topic in 1–2 weeks
- 1Week 1: Focus on biology topics. Revise the characteristics of living things and plant/animal cells. Create flashcards for key terms and test yourself daily.
- 2Week 2: Move to chemistry. Learn about states of matter and changes of state. Practise drawing particle diagrams and identifying physical vs chemical changes.
- 3Week 3: Study physics concepts: forces, energy, and simple circuits. Do practical activities at home, like building a circuit with a battery and bulb.
- 4Week 4: Review all topics and practise past exam questions. Focus on command words and time management. Work through the worked examples in this guide.
Exam Question Types
How this topic typically appears in the exam
- 📋Multiple-choice questions: Read each option carefully and eliminate obviously wrong answers. Look for key words like 'not' or 'always'.
- 📋Short-answer questions: These often ask you to 'state' or 'name' something. Give a concise answer, but include a unit if needed.
- 📋Practical-based questions: You may be given a scenario and asked to identify variables, suggest a method, or analyse results. Use the data provided.
- 📋Extended response questions (6 marks): These require a structured answer. Plan your response, use scientific terms, and include examples or data.
Command Word Expectations (WJEC-CBAC)
What examiners look for when using specific command words in this specification
Give a brief, factual answer without explanation. For example, 'State one safety precaution' – just name it.
Give a detailed account of what happens or what you see. Include observations or steps in a process.
Give reasons or causes. Use 'because' to link your points. For example, 'Explain why the bulb is not lit' – give a reason.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A student investigates how the temperature of water affects the time taken for sugar to dissolve. They use 50 cm³ of water at 20°C, 30°C, 40°C, and 50°C. They stir each beaker and record the time. Describe how they could make this a fair test and state one safety precaution.
- 1.Step 1: Identify the independent variable (temperature) and dependent variable (time to dissolve).
- 2.Step 2: List control variables: same amount of water (50 cm³), same amount of sugar, same stirring speed, same type of beaker.
- 3.Step 3: State a safety precaution, e.g., wear goggles to protect eyes from hot water splashes.
Question: A circuit has a battery, a bulb, and a switch connected in series. The bulb is not lit. Give two possible reasons why the bulb is not lit.
- 1.Step 1: Think about what is needed for a circuit to work: a complete loop and a source of energy.
- 2.Step 2: Consider possible faults: broken wire, loose connection, flat battery, blown bulb, or switch open.
- 3.Step 3: Choose two clear reasons and explain them.
