Pikelet Product Improvement

Overview

Lesson 20 of 30 in From Fruit to Baking. Students use evidence from earlier pikelet trials to identify one problem, propose one justified improvement, test it safely, and evaluate whether the change improved the product or process.

Learning intentions

• WALT use evaluation evidence to identify an opportunity for improvement.
• WALT propose a change to a pikelet process or product and explain why it may help.
• WALT carry out a fair, safe comparison test.
• WALT communicate an evidence-based recommendation.

Success criteria

• I can identify a specific strength or problem using evidence.
• I can describe one achievable improvement and predict its effect.
• I can test my change while keeping other factors as consistent as possible.
• I can use observations and feedback to recommend whether the change should be adopted.

Curriculum links

• Technological practice: planning, developing, testing and evaluating a food product or process.
• Food technology: understanding how ingredients, equipment, techniques and conditions affect outcomes.
• Design thinking: identifying a need, generating an idea, testing it and improving through feedback.
• Key competencies: thinking; managing self; participating and contributing; relating to others; using language, symbols and texts.

Lesson structure (45 minutes)

1. 0–5 min – Hook and recall Display a before-and-after pikelet comparison using the hook and comparison slides. Ask: “Which pikelet would a customer choose, and what evidence supports your decision?” Students briefly recall findings from the previous pikelet lesson.

2. 5–10 min – Make the improvement measurable Use the evaluation teaching slides to revisit possible variables: batter consistency, portion size, cooking temperature and presentation. Model turning a vague idea such as “make it better” into a testable statement: “If the portion is smaller, the pikelet will cook more evenly.” Emphasise changing one main variable and keeping other conditions as consistent as possible.

3. 10–15 min – Plan in teams In groups of four or five, students review their earlier evaluation evidence and select one improvement. Distribute the pikelet improvement planning sheet. Students record the problem, proposed change, prediction, materials, method, safety controls and evidence they will collect. Groups may use the design thinking process cards as a visual reminder of the stages.

4. 15–30 min – Test the improvement Groups prepare and cook a small comparison: their improved version alongside the agreed baseline version, where practical. Students follow the class recipe, measure carefully, use oven mitts and teacher-approved equipment, and keep hands, surfaces and utensils clean. One student manages equipment, one measures, one records, and one observes; rotate roles if time allows. The teacher supervises all heat use and checks plans before cooking.

5. 30–37 min – Evaluate the evidence Groups compare appearance, texture, size, colour, taste and ease of making. They record observations and peer feedback on the pikelet comparison and evidence table. Prompt: “What changed, what stayed the same, and what evidence shows whether the improvement worked?”

6. 37–42 min – Share recommendations Each group gives a 30-second report using the structure on the sharing and discussion slides: “We changed… We noticed… Our evidence suggests… We recommend…” Class members ask one respectful question or offer one useful suggestion.

7. 42–45 min – Individual reflection and pack-up Students complete the final reflection on the individual recommendation section while groups clean work areas and return equipment. Invite two students to share how evidence, rather than preference alone, influenced their recommendation. Finish with the plenary slide.

Resources

• Ingredients and recipe from the class pikelet practical
• Prepared baseline batter or pikelets, if needed to save time
• Bowls, spoons, measuring equipment and cooking equipment
• Frying pans or electric cooking appliances, with teacher supervision
• Plates, tasting utensils, paper towels and cleaning materials
• Food-safe sanitiser and handwashing facilities
• the Pikelet Product Improvement slide deck
• the Pikelet Improvement Planning Sheet
• the Design Thinking Process Cards
• Aprons and oven mitts

Assessment

• Observe group planning and questioning: students should identify one variable, justify a change and describe how it will be tested.
• Check the worksheet for a clear prediction, controlled method, relevant observations and an evidence-based recommendation.
• Listen to group reports and individual reflections for accurate use of evaluation language, including evidence, comparison, strength, limitation and improvement.

Differentiation

• Provide a choice board with the four suggested improvement areas and sentence starters such as “The evidence shows…” and “We predict…”.
• Pair students strategically and assign manageable roles; provide a completed example of one planning row for students needing additional support.
• Allow oral recording, labelled diagrams or teacher scribing for students with writing or language needs. Pre-teach key words with pictures and demonstrate each safety step.
• Extend confident students by asking them to identify a limitation in their test, suggest a second trial, or consider how the improvement affects cost, time, waste and customer appeal.
