Duration: 50 minutes

Starter Activity (5 minutes)

Quick Recall

Write down everything you already know about nea task 1: food investigation. Then check against the key terms: key terms from nea task 1: food investigation. Use a mini-whiteboard or paper.

Main Content (35 minutes)

Parent/Teacher Guide:
Before lesson: Read the script below. Pre-teach key vocab: key terms from nea task 1: food investigation.
If stuck: Re-read the revision notes (link above), then break the content into smaller steps.
Extension: See the Stretch & Challenge ideas in Lesson 4.
Teaching Script (35 mins):
Mins 0-5 - Hook: "Today: nea task 1: food investigation. By the end you will be able to answer exam questions on it unaided. It connects to the rest of Food Preparation and Nutrition because the ideas here recur across the spec."
Mins 5-20 - Direct Instruction: Work through the core ideas below one at a time; after each, ask your student to explain it back in their own words.
Mins 20-30 - Guided Practice: Model the worked example together, then let your student attempt the first practice question with guidance.
Mins 30-35 - Independent Practice: 2-3 practice questions from Lesson 3 below, with immediate feedback.
First Look

Lesson 2: Core Concepts: nea task 1: food investigation

Duration: 50 minutes

Starter Activity (5 minutes)

Review Previous Lesson

Quick recap: write 3 key points from Lesson 1 on nea task 1: food investigation. Check them against the notes below.

Main Content (35 minutes)

Key Fact: NEA Task 1 is a food investigation worth 15% of the total GCSE grade (AQA 8585). It is completed in controlled conditions over approximately 10 hours.
Key Fact: The investigation assesses students' understanding of the working characteristics, functional properties, and chemical processes of ingredients.
Key Fact: Task 1 involves: researching the given brief, conducting practical experiments, recording results, and writing a scientific report (1,500–2,000 words plus supporting evidence).
Key Fact: A typical Task 1 brief might ask you to investigate how different raising agents affect the volume and texture of a sponge cake, or how different fats affect pastry shortness.
Key Fact: The investigation must include: a hypothesis or prediction, controlled variables, a method, results table, analysis, and a conclusion linked to food science.
Key Fact: Controlled variables are essential: to test the effect of one ingredient, all other variables (temperature, quantities, timing, equipment) must be kept constant.

Extended Answer

Extended question: Full-Mark Response You are investigating how different raising agents affect the volume and texture of a sponge cake. Describe how you would conduct this investigation, including variables and how you would ensure reliable results. (8 marks) <div class="

I would investigate how three raising agents — baking powder, bicarbonate of soda, and self-raising flour — affect sponge cake volume and texture. The independent variable is the type of raising agent. The dependent variables are cake volume (measured in cm³ by displacement or height) and texture (assessed by sensory evaluation). Controlled variables include: 50g each of flour, sugar, butter, and one egg; oven temperature 180°C; baking time 20 minutes; same mixing method (creaming); same cake tin size and material; same cooling time before measurement. I would make three cakes, changing only the raising agent: Cake A uses baking powder (1 teaspoon), Cake B uses bicarbonate of soda (half teaspoon, with an acidic ingredient like lemon juice), Cake C uses self-raising flour (replacing plain flour). After baking and cooling, I would measure the height and volume of each cake, photograph cross-sections, and conduct a sensory evaluation with at least three testers rating texture, lightness, and overall acceptability on a 1–5 scale. Results would be recorded in a table comparing raising agent, height, volume, and sensory scores. I would repeat the experiment once to verify reliability. In

Exam Tips: Structure your investigation report clearly: Introduction, Research, Hypothesis, Method, Results, Analysis, Conclusion. | Always name your variables: independent (what you change), dependent (what you measure), controlled (what you keep the same). | Use food science terminology in your analysis: say 'denaturation of proteins' not 'the egg went hard', 'gelatinisation of starch' not 'the sauce thickened'. | Photograph every stage of your investigation — visual evidence is essential supporting evidence.
Common Errors: ✗ Task 1 is a cooking practical with no written work. ✓ Task 1 is primarily a scientific investigation with a written report (1,500–2,000 words). Practical experiments provide evidence, but the report demonstrating understanding of food science is what is assessed. ✗ You don't need to control variables in a food investigation. ✓ Controlling variables is essential. If you change more than one factor between tests, you cannot know which factor caused the observed difference in results. Only the independent variable should change. ✗ The conclusion just describes what happened. ✓ The conclusion must explain results using food science. Don't just say 'the cake with bicarbonate of soda was larger'
Stretch & Challenge (Grade 8-9):
  • Synoptic links: explain how nea task 1: food investigation connects to another Food Preparation and Nutrition topic you have studied
  • Real-world: research one real-world use or example of nea task 1: food investigation
  • Critical: "What are the limitations of the models used in nea task 1: food investigation?"
