Assessment Guidance
Guidance for achieving higher grades
- 💡When describing impacts, use the SEE structure: State the impact, Explain the cause, and give an Example for clarity and depth.
- 💡For communication tasks, clearly label the intended audience and purpose, then consciously choose vocabulary and format—e.g., a leaflet for the public vs. a report for scientists.
- 💡Revise key vocabulary such as 'quarrying', 'leaching', 'sustainability', and 'by-product' to accurately describe processes and impacts.
- 💡Always refer to a specific example of a useful substance (e.g., oil, copper, limestone) in your answers.
- 💡When asked to communicate to a different audience, use everyday language and avoid technical jargon.
- 💡In portfolio tasks, always start by clearly stating the substance and the method used to obtain it.
- 💡Use specific vocabulary such as 'deforestation', 'carbon emissions', or 'reclamation' to show depth of understanding.
- 💡For communication assignments, create a rough plan matching key points to the audience’s needs before developing the final output.
- 💡Support your written work with simple labelled diagrams or flowcharts to clarify processes and impacts.
- 💡Show Your Practical Skills Clearly: Many marks in this qualification come from demonstrating practical competence. When carrying out investigations, ensure you follow instructions carefully, use equipment correctly, and record your observations or measurements accurately. Don't just do the task; make sure the examiner can see you doing it well.
- 💡Use Correct Scientific Vocabulary: Even at Entry 3, using the right scientific terms shows understanding. For example, instead of saying "the stuff got hot," use "the temperature increased." Practice using words like "observe," "measure," "predict," "hazard," "material," and "force" correctly in your answers.
- 💡Explain Your Reasoning Simply: When asked to explain 'why' or 'how', provide clear, concise answers using simple language. For instance, if asked why you wear goggles, a good answer would be "to protect my eyes from splashes," rather than just "safety." Focus on providing a direct and relevant explanation.
Common Mistakes
Common errors to avoid in your coursework
- Confusing the terms 'useful substance' and 'raw material', leading to vague descriptions of extraction processes.
- Focusing solely on environmental negatives without considering social or economic benefits, resulting in an unbalanced assessment.
- Failing to adapt language and content when communicating to different audiences, often using overly technical terms for a non-specialist group.
- Confusing the processes of extraction with manufacturing or product creation.
- Believing that all substances can be obtained without any negative consequences.
- Mixing up environmental impacts with social impacts.
- Confusing renewable and non-renewable resources and their extraction impacts.
- Providing vague impacts (e.g., 'damages the environment') without concrete examples.
- Neglecting to tailor communication for the intended audience, leading to inappropriate tone or complexity.
- Overlooking the economic benefits of obtaining substances, focusing only on negative effects.
- Mistake: Believing that a prediction is just a guess, rather than an informed idea based on what you already know or observe. Correction: A prediction in science is an educated guess about what might happen, often based on prior knowledge or patterns you've noticed. It's a starting point for your investigation, not just a random thought.
- Mistake: Thinking that if an experiment doesn't work as expected, it's a failure and the results are useless. Correction: In science, unexpected results are valuable! They can lead to new questions or show you something you hadn't considered. It's important to record all results accurately, even if they don't match your prediction, and try to explain why they occurred.
- Mistake: Ignoring safety instructions because a task seems simple or you've done it before. Correction: Safety rules are always important, no matter how simple the task. Always listen to your teacher, wear appropriate personal protective equipment (PPE) like safety goggles if required, and handle equipment carefully to prevent accidents.
