Students will develop, refine and justify a pavlova dessert concept that is fit for purpose and suitable for sale at a farmers’ market.
Lesson 1 = concept development and Lesson 2 = final design, evaluation and pitch, then Lesson 3 should move from design into practical production.
In this first lesson of a three-lesson design sequence, students develop and refine a pavlova dessert concept for sale at a farmers’ market. They will respond to a design brief, consider users and market context, and justify decisions about flavour, presentation, packaging, cost and food safety. Lesson 2 will develop the final design, evaluation and pitch; Lesson 3 will move from design into practical production.
0–7 min · Hook and context. Teacher displays the pavlova market hook and design brief showing two contrasting pavlovas and asks, “Which one would you buy at a farmers’ market, and why?” Students make an individual choice, then discuss visual appeal, likely customers, price, portability and perceived quality with a partner. Establish the brief: Design a pavlova dessert concept that is attractive, practical, safe and suitable for sale at a local farmers’ market.
7–16 min · Unpack the brief. Teacher uses the design brief and fit-for-purpose criteria to model the difference between a preference and a design requirement. Students identify users, purpose and constraints, recording at least one requirement under each heading: customer appeal, ingredients and seasonality, presentation, packaging, cost, food safety, sustainability and production time. Clarify that students are designing a concept today, not preparing food. Discuss the need to avoid unsupported health claims and to identify allergens such as egg and dairy where relevant.
16–25 min · Investigate and ideate. Teacher models rapid idea generation, combining a pavlova base with seasonal fruit, textures, sauces and presentation ideas. Students use the pavlova concept development worksheet to create three quick concept options, each including a target customer, flavour combination, serving format and packaging idea. Encourage quantity first; refinement comes later. Students may use familiar farmers’ market products or teacher-provided ingredient images as prompts, while considering seasonality and availability in Aotearoa New Zealand.
25–34 min · Select and develop. Teacher explains a simple decision check: “Does it appeal, can it be made consistently, can it be transported, can it be sold safely and can the likely price cover its cost?” Students select their strongest concept and develop an annotated sketch on the worksheet. Annotations must identify ingredients, layers, portion size, decoration, packaging, likely price range and one sustainability choice. Circulate and question students: “Who is your customer?”, “What evidence supports that choice?”, and “What could fail during production or transport?”
34–45 min · Peer feedback carousel. Teacher displays the peer feedback questions and refinement routine and forms groups of four. Each student explains their concept in 60 seconds; peers give one strength, one concern and one actionable suggestion using the prompts: “This is fit for purpose because…”, “A possible issue is…”, and “To improve it, I suggest…” Students listen respectfully, record useful feedback and ask one clarifying question. Remind students to critique the design, not the person.
45–55 min · Refine and justify. Teacher models turning feedback into a design decision, such as changing a delicate topping or revising packaging for transport. Students revise their sketch and complete a short justification: “My target customer is… My concept meets the brief because… I changed… after feedback because… A production or safety consideration is…” Students who finish early estimate a realistic selling price and list the information they would need before confirming it.
55–61 min · Share and exit check. Teacher uses the plenary and exit prompts to invite two or three students to share a refined concept and one design decision. Students complete the final section of the concept review and next-step section: strongest feature, greatest risk, and one question to resolve in Lesson 2. Collect worksheets as evidence of progress and preview the final design, evaluation and pitch.
