Practical and Project Work: Investigation, Recording and Evaluation
Practical and project work tests whether you can plan a small investigation, follow safe procedures, record observations and draw a limited conclusion. The viva often asks why a step was done, not only what was done.
Core rules
- Project sequence: identify the problem, state objectives, plan methodology, prepare tools or recipes, collect data, analyse, conclude, and note limitations.
- Records should contain aim, materials, procedure, observations or results, conclusion and references. Keep raw data and calculations.
- Food practicals require personal and kitchen hygiene, accurate weighing, standardised recipes, safe handling and sensory evaluation. A nine-point hedonic scale rates liking from 1 (dislike extremely) to 9 (like extremely).
- Textile practicals may involve fibre identification by burn test, basic stitches, seams, pattern drafting and fit evaluation.
- Child study or community survey requires consent, confidentiality, non-judgemental observation and accurate reporting.
Worked example
Ten judges evaluate three ladoo samples using a nine-point hedonic scale. Reasoning: code samples with random numbers, give water between samples, avoid leading descriptions, and calculate the mean score for each sample. The highest mean indicates preference, not nutritional superiority. Report the panel size, scale and limitation that preference is subjective. This shows method, analysis and interpretation.
Traps
Testing without codes or random order; asking leading questions; omitting consent or confidentiality; copying a project without local data; ignoring cost and food safety; ending without a conclusion or limitation.
Exam focus
Method steps, safety, sensory evaluation, data presentation and viva explanation.
