Assessment Guidance
Guidance for achieving higher grades
- 💡Provide a reflective account that details your decision-making process: how you identified the need for new resources, consulted with teaching staff, and ensured alignment with curriculum goals.
- 💡Include a variety of evidence types: photographs of final set-ups, annotated risk assessments, feedback from teachers, and any pilot trial results.
- 💡Cross-reference your evidence against each learning outcome clearly, using an index or mapping to help the assessor locate relevant information.
- 💡Always show your working in calculations, even if the answer is wrong, you may gain method marks.
- 💡Use correct scientific terminology in your answers, such as 'meniscus', 'calibration', 'tare', and 'aliquot'.
- 💡When answering questions about procedures, write in a logical order and include safety points to demonstrate a full understanding.
Common Mistakes
Common errors to avoid in your coursework
- Failing to consider the age, ability, and prior knowledge of learners when selecting methods and resources, leading to inappropriate or unsafe activities.
- Not trialling or testing prepared resources beforehand, which can result in practical activities failing during teaching sessions.
- Overlooking the need for basic risk assessments and safety protocols when introducing new methods or substances.
- Submitting insufficient or unclear photographic evidence and witness testimonies that do not explicitly link to the learning outcomes.
- Misconception: 'A hazard and a risk are the same thing.' Correction: A hazard is something with the potential to cause harm, while risk is the likelihood of that harm occurring. For example, a chemical is a hazard; the risk is how likely it is to cause harm based on how it is used.
- Misconception: 'When using a pipette, you should blow out the last drop to ensure accurate volume.' Correction: Blowing out the last drop can introduce error because the pipette is calibrated to deliver the specified volume without the last drop. Always allow natural drainage.
- Misconception: 'Precision and accuracy mean the same thing.' Correction: Accuracy refers to how close a measurement is to the true value, while precision refers to how consistent repeated measurements are. A measurement can be precise but not accurate.

Step-by-Step Worked Solutions
Detailed solution breakdown for typical exam problems
Question: A technician needs to prepare 500 cm³ of a 0.1 mol/dm³ sodium hydroxide solution. Calculate the mass of sodium hydroxide (NaOH) required. (Relative atomic masses: Na=23, O=16, H=1)
- 1.Step 1: Calculate the molar mass of NaOH: 23 + 16 + 1 = 40 g/mol.
- 2.Step 2: Convert volume from cm³ to dm³: 500 cm³ = 0.5 dm³.
- 3.Step 3: Use the formula: mass = concentration × volume × molar mass = 0.1 mol/dm³ × 0.5 dm³ × 40 g/mol = 2 g.
- 4.Step 4: State the final answer with units: 2 g of NaOH is required.
Question: Describe how you would accurately measure 25.0 cm³ of a liquid using a pipette. Include safety and technique points.
- 1.Step 1: Select a clean, dry 25 cm³ pipette and a pipette filler.
- 2.Step 2: Rinse the pipette with the liquid to be measured to avoid contamination.
- 3.Step 3: Use the pipette filler to draw the liquid above the graduation mark.
- 4.Step 4: Remove the filler and quickly place a finger over the top. Adjust the meniscus so the bottom of the meniscus is exactly on the mark.
- 5.Step 5: Transfer the liquid to the receiving vessel, allowing it to drain naturally. Do not blow out the last drop.
- 6.Step 6: Safety: wear safety goggles and gloves, and work in a well-ventilated area.
