Grains: Paddock to Plate

Overview

In this second lesson of Paddock to Purpose Design, students trace wheat from a living grain plant to a finished food product. Through explicit modelling, collaborative sequencing and flowchart design, they identify how technologies transform and move grains through managed food-production systems.

Learning intentions

Students will:

• explain that grains are grown as plants before being processed into food
• sequence key stages from planting to consumption
• identify technologies used at different stages of production
• communicate a connected process using a labelled flowchart
• consider a sustainability question about grain production

Success criteria

I can:

• show the stages in a logical paddock-to-plate order
• explain at least four technologies used in the process
• distinguish a wheat plant from a finished food
• name one stage and ask one sustainability question

Curriculum links

• Explain how food and fibre are produced in managed environments.
• Explain how characteristics of foods influence selection and preparation for healthy eating.
• Develop project plans that consider resources for individually and collaboratively made solutions.
• Explain how materials, systems, tools and equipment affect designed solutions, and select suitable technologies safely.

Lesson structure (60 minutes)

1. 0–5 min · Retrieval and hook. Display the retrieval and learning-intention slides from the paddock-to-plate teaching deck and ask: “Where does bread begin?” Students answer individually, then compare responses with a partner; address the misconception that grains are manufactured rather than grown. Ask students to show thumbs up, sideways or down for: “Wheat is a plant”, “Flour is grown in a paddock” and “A combine harvester is a technology”.

2. 5–13 min · Explicit modelling — I do. Use the paddock-to-plate teaching deck and a wheat product package to model the sequence: planting, growing, harvesting, transport, milling, processing, packaging, retail and consumption. Explain that wheat is a plant, while flour, bread and pasta are products made from harvested grain; think aloud using “What changes here?” and “What technology makes this possible?” Students listen, repeat key terms and record two examples of a grain plant and two finished foods on the grain journey worksheet.

3. 13–25 min · Guided investigation — We do. Display the investigation prompt on the paddock-to-plate teaching deck. In groups of four, students examine picture process cards, food packages and arrows, then jointly arrange the stages in order. Prompt groups to identify technologies such as seed drills, irrigation, tractors, combine harvesters, trucks, silos, mills, ovens and packaging equipment. Pause after each stage for a class check: students hold up the next card and explain what has changed and why the technology is useful. Clarify that technologies include tools, machinery, systems and processes.

4. 25–45 min · Group flowchart — You do. Assign groups of four a large sheet of paper and roles: facilitator, materials manager, recorder and reporter. Use the group role cards to clarify responsibilities, then provide the grain journey worksheet as a planning scaffold for groups requiring support. Each group creates a labelled paddock-to-plate flowchart with arrows, at least eight stages and at least four technologies. Students add a brief explanation at selected stages, using the prompts “What changes here?” and “What technology makes this possible?” Circulate to check accurate sequencing, technical vocabulary and the distinction between the plant and processed food. Ask early finishers to compare two grain products or suggest one resource-saving improvement.

5. 45–55 min · Gallery feedback. Display the feedback prompts on the paddock-to-plate teaching deck. Groups leave their flowchart on the table while students rotate, silently inspect two other flowcharts and provide one specific strength and one question, such as “Your milling stage is clear” or “How is grain stored safely?” Groups return to their work, read the feedback and make one improvement. Invite two groups to explain a technology and the change it enables.

6. 55–60 min · Knowledge check and exit. Revisit the success criteria on the paddock-to-plate teaching deck. Students complete the success criteria exit ticket slips by naming one stage, one technology used there and one sustainability question. Collect flowcharts and slips as evidence of learning.

Resources

• the paddock-to-plate teaching deck
• the grain journey worksheet
• the group role cards
• the success criteria exit ticket slips
• Go Grains images or short video clips
• Wheat, flour and grain-product packages
• Grain process picture cards
• Large paper, markers and sticky notes
• Arrows or reusable arrow cards

Assessment

• During retrieval and guided sequencing, listen for the misconception that grains are made rather than grown, and check students’ use of terms such as harvest, milling, processing and packaging.
• During group work, use a checklist for logical sequence, clear arrows, four or more correctly matched technologies and explanations of what changes.
• Use the flowcharts and exit slips to identify students needing further support with managed environments, food-production technologies or sustainability.

Differentiation

• Provide a numbered stage bank, word bank, picture-supported process cards and a partially completed flowchart template for students requiring support.
• Pair students strategically and rehearse explanations orally before they write; allow drawing, labelled phrases or speech-to-text where appropriate.
• Use clear visuals, gestures and repeated sentence stems for EAL/D learners: “At this stage, ___ changes into ___ because ___.”
• Extend confident students by comparing two grain products, considering different processing requirements or proposing a resource-saving improvement with a reason.
