Pack It Sustainably

Overview

Students investigate how packaging can meet a community need while reducing environmental impact. They examine a lunchbox packaging problem, compare design ideas using a simple digital tool, and communicate an annotated design with a clear sequence of making steps.

Learning intentions

Students will:

• examine how sustainability influences the design of a product.
• identify the needs of a lunchbox user and generate possible solutions.
• use digital tools to compare design ideas.
• sequence the steps needed to make a designed solution.
• communicate design decisions using labelled drawings and technical vocabulary.

Success criteria

• I can explain at least two needs my packaging design must meet.
• I can describe how my design reduces waste or saves resources.
• I can create and compare two design ideas using a digital tool.
• I can draw and label one design and sequence its making steps.

Lesson structure (53 minutes)

1. 0–6 min · Hook and community need. Open with the opening lunchbox comparison showing a single-use snack packet beside a reusable or compostable alternative; ask, “Which design better meets a student’s needs, and what might happen to each package after lunch?” Students silently notice, think-pair-share, then contribute ideas such as protection, convenience, cost, safety and reduced waste.

2. 6–14 min · Explicit teaching. Use the sustainability teaching slides to introduce the design brief: “Design packaging for one school snack that protects the food, is easy to use and creates less waste.” Explain that designers consider users, materials, function, appearance, safety, accessibility and sustainability. Model technical vocabulary including product, user, material, reusable, recyclable, compostable, durable and design feature. Students help identify which features would make packaging suitable for different users, including a student with limited hand strength or vision.

3. 14–22 min · Investigate and plan. Distribute the sustainable packaging design brief. Students identify the intended user, list three needs and circle or write sustainability considerations. In pairs, students examine familiar packaging or teacher-provided photographs and record one useful feature and one possible environmental concern. Conduct a quick check by asking pairs to justify one design requirement.

4. 22–32 min · Generate and compare digitally. Demonstrate the digital design comparison instructions. Students work in groups of three using a shared slide, drawing app or simple word-processing table to create two thumbnail designs. Each design must include a material choice and one accessibility feature. Groups compare their ideas against the brief using three headings: meets the user’s needs, reduces environmental impact and is practical to make. Students choose one design and give a reason for their decision.

5. 32–44 min · Communicate and sequence. Students use the selected idea to complete an annotated drawing on the sustainable packaging design brief. They label at least four features, such as lid, fold, handle, recycled card or washable fabric, and write a short explanation of how the design works. They then number five or six making steps, for example measure, mark, cut, fold, join and test. Groups may use the group role cards to share responsibilities such as designer, materials manager, recorder or reporter. Circulate and ask, “What will happen first?”, “Which resource will you need?” and “How will you test safety and strength?”

6. 44–49 min · Design share and feedback. Display the peer-feedback prompts. Each group gives a 30-second explanation of its chosen design, material and sustainability decision. Listening groups provide one specific positive comment and one question, focusing on the success criteria rather than artistic appearance. Students make one small improvement to their drawing or sequence.

7. 49–53 min · Exit assessment. Use the plenary and exit questions to revisit the learning intention. Students complete the final prompts on the worksheet: “My design meets the user’s need by…” and “One sustainable choice I made was…”. Invite two or three students to share. Collect the worksheets and digital designs for assessment.

Resources

• the sustainable packaging design slide deck
• the sustainable packaging design brief
• the group role cards
• Student devices with a shared presentation, drawing app or word-processing tool
• Projector or interactive display
• Teacher-provided clean packaging, photographs or material samples
• Pencils, coloured pencils and rulers
• Optional recycled card, paper, fabric scraps and tape for examining materials
• Timer and visible success criteria

Assessment

• During discussion, check whether students can identify user needs and explain how sustainability affects a design choice.
• Review digital comparisons and annotated drawings for two generated ideas, a justified choice, appropriate technical vocabulary and consideration of accessibility.
• Use the completed sequence and exit responses to assess whether students can order production steps and communicate a sustainable design decision.

Differentiation

• Provide picture-supported vocabulary, a word bank, a partially completed design brief and sentence starters such as “My user needs…” and “This material is sustainable because…”.
• Allow students to explain ideas orally, record an audio response or use speech-to-text; pair students strategically and offer enlarged worksheets or a digital version.
• Give students who need additional support a choice of two user profiles and pre-selected materials to compare.
• Extend confident students by asking them to include an estimated cost, explain how the product could be repaired or reused, or propose a fair test for strength, waterproofing or ease of opening.
• Use clear roles, shared devices and an accessible workspace so students with mobility, sensory, language or attention needs can participate in the same design process.
