Recording results clearly is an important part of AQA GCSE Food Preparation and Nutrition NEA Task 1. Your results should show what happened during your food investigation, not simply describe the final product. Well-organised tables, suitable photographs and carefully collected sensory data help a reader understand your experiment and judge your conclusions. This guide explains how to record practical findings accurately, choose useful evidence and link your results to the food science being investigated. Always follow your teacher’s instructions and check the current AQA specification because assessment guidance can change.
What should your results show?
NEA Task 1 is a food investigation. You investigate a food science question by changing or comparing something, carrying out practical work and examining the effect. Your results section should make the investigation easy to follow.
Results are the evidence collected during the practical work. They might include measurements, observations, photographs and sensory judgements. Your results should help answer questions such as:
- What variable was changed?
- What stayed the same to make the comparison fair?
- What happened to the food as a result?
- What evidence supports your conclusion?
For example, if you investigate how changing an ingredient affects the texture of a baked product, you could record the quantities used, the method conditions, observations during preparation and the final sensory qualities. Your conclusion should then refer back to this evidence rather than relying only on personal opinion.
Use tables to organise measurements
A table is usually clearer than writing a long list of results in a paragraph. Give the table a useful title and label every column. Include units, such as grams, millilitres or minutes, where they apply. Record results carefully and use the same level of precision throughout where appropriate.
| Trial or sample | Variable changed | Measurement or observation | Result |
|---|---|---|---|
| Sample A | Lower level | Appearance and texture | Record your finding |
| Sample B | Middle level | Appearance and texture | Record your finding |
The headings in this example would need adapting to your own investigation. Do not include a measurement column if you have not actually measured it. Equally, do not leave a reader guessing what a number means.
Raw and processed results
Raw results are the information collected directly during the practical work, such as a measurement or an observation. Processed results are results that have been organised or calculated so that patterns are easier to see. This might include a mean, which is an average, if it is suitable for your investigation and your teacher has advised you to use one.
Keep your original results visible. If you calculate an average or create a chart, show how it was obtained and make sure the calculation does not hide important differences between samples. A graph or chart should have a clear title, labelled axes and suitable units where relevant. Only use a chart when it helps the reader see a pattern more easily than a table.
Record observations precisely
Observations describe what you can see, smell, feel or hear during the practical process. They should be specific rather than vague. Instead of writing “it was better”, record a feature that can be compared, such as “the mixture became thicker after whisking” or “the final product had a more even surface”.
Use appropriate food vocabulary, but explain unusual technical terms when necessary. Words such as cohesive, meaning holding together, or crisp, meaning firm and brittle when bitten, can make your observations more precise. Avoid claiming that a product is healthier, safer or more nutritious unless your investigation has produced suitable evidence for that judgement.
Use photographs as supporting evidence
Photographs can show changes that are difficult to explain in words. For example, images may help compare the appearance, volume, colour, shape or structure of samples. Take photographs that are relevant to the investigation and make sure the samples can be identified clearly.
- Photograph samples in a consistent way where possible, so comparisons are fair.
- Use clear labels or captions to identify the sample and the stage shown.
- Include a useful range of images rather than many nearly identical photographs.
- Link each photograph to the written result it supports.
A photograph does not replace written observations or measurements. It is evidence alongside your table and explanation. If lighting, camera angle or portion size changes between photographs, be careful not to claim that the difference proves a change in the food.
Record sensory data carefully
Sensory evaluation is the systematic assessment of food using the senses. It can include appearance, aroma, flavour, texture and sometimes sound. A sensory test should be planned so that the results can be compared fairly.
You might use a rating scale, for example asking a taster to score a quality from low to high. Explain what the scale means and keep the wording consistent. A score without a description is difficult to interpret. You could also use descriptive words, such as “smooth”, “dry”, “soft” or “strong aroma”, if that suits the investigation.
Record the method used, the samples tested and the responses collected. Consider whether the tasters understood the scale and whether the samples were presented fairly. Follow your school’s instructions about allergies, hygiene, consent and safe tasting. Food safety and allergy guidance can change, so check current advice from your teacher and the Food Standards Agency or other relevant official source before carrying out tasting.
Turn results into analysis
Recording results is not the same as analysing them. Analysis explains what the results mean. Look for patterns, similarities, differences and unusual findings. Then connect these to the food science principle being investigated.
Useful analytical sentences include:
- “As the level of the changed ingredient increased, the product became…”
- “The sensory scores suggest that…”
- “This result may be linked to…”
- “Sample C did not follow the overall pattern because…”
Use cautious language when the evidence is limited. A result may suggest a relationship without proving that one factor caused every change. Your evaluation can discuss the reliability of the investigation, meaning how consistently it produced similar findings, as well as limitations such as an unclear scale, inconsistent portion sizes or a small amount of sensory feedback.
Exam-ready checklist
- Have I recorded the results from each sample or trial I actually completed?
- Are my tables clearly titled, organised and labelled with units where needed?
- Have I separated direct observations from calculations or averages?
- Do my photographs have clear captions and support a written result?
- Have I explained the sensory scale or descriptive method used?
- Have I identified patterns rather than simply listing results?
- Have I linked my findings to the food science principle investigated?
- Have I acknowledged limitations without inventing evidence?
For the official specification and current assessment information, consult the AQA GCSE Food Preparation and Nutrition specification. Your teacher’s instructions remain important because they will explain how to present your own NEA evidence.
Frequently asked questions
Do photographs count as results?
Photographs can be useful results evidence, especially for appearance and comparison. They should support, not replace, written observations, measurements and sensory data where these are relevant.
Should every result be put into a graph?
No. Use a graph or chart only when it makes a pattern easier to understand. A well-labelled table may be clearer for descriptive observations or a small set of results.
Can I change a result that looks unusual?
No. Keep an unusual result and consider why it occurred. Check your recording and calculations, then explain any possible limitation honestly rather than altering the evidence.
