Curriculum Links

Australian Curriculum – Science (Version 9.0):

• Science as a Human Endeavour (Years 5–6):
  • VCSSU073: Scientific knowledge is used to solve problems and inform personal and community decisions.
• Design and Technologies (Years 5–6):
  • VCDSCD040: Critique needs or opportunities for designing and investigate materials, components, tools, equipment, and processes to achieve intended designed solutions.
  • VCDSCD042: Generate, develop and communicate design ideas using appropriate technical terms and graphic representation techniques.

---

WALT – We Are Learning To:

• Translate our sustainable design ideas into initial prototypes.
• Choose appropriate materials based on environmental impact and functionality.
• Apply basic construction techniques to bring a design to life.

---

Success Criteria:

✅ I can sketch a clear prototype design that links to my sustainability problem and criteria.
✅ I can explain why I chose specific materials and features for my design.
✅ I can begin construction of a prototype using safe and effective techniques.

Resources:

• Student Design Briefs from Lesson 6
• A3 sketch paper and pencils/coloured pencils
• Recycled and sustainable materials (e.g. cardboard, paper straws, reusable fabrics, tape, string, wood off-cuts, plastic lids, wire)
• Construction tools (scissors, hole punchers, low-heat glue guns – teacher supervised, rulers)
• “Materials Decision Map” (teacher handout)
• Visualiser/Projector
• Aprons or protective wear

Lesson Outline (60 Minutes)

1. Introduction (10 minutes) – Igniting Creativity

• Teacher-led Review: Briefly recap the design challenge from last lesson—they’ve identified a local sustainability problem (e.g. plastic waste, water conservation, energy efficiency).
• Class Discussion Prompt: “What’s one simple but powerful tool or material you might use to help the environment?”
• Showcase Examples: Display 2–3 examples of real-world sustainable product prototypes (teacher-prepared visuals or past student work). Highlight how everyday items can be redesigned for sustainability.

✳️ Teacher Tip: Use storytelling here to introduce a powerful example – like how a student in Northern Territory turned coconut husks into reusable cleaning pads.

2. Design Sketching & Planning (15 minutes) – Constructive Thinking

• Individual/Pairs Planning Phase: Students sketch their idea on A3 paper – including annotations that explain intended functions and sustainable features (across water, energy, materials, or waste systems).
• Provide students with the “Materials Decision Map” to help them evaluate recyclability, durability and environmental footprint of available supplies.
• Circulate and provide feedback, encouraging practical refinements (“What might happen if this gets wet?” or “Is there a more sustainable alternative to this material?”)

🎯 Differentiation:

• Support: Provide scaffolded sketch templates with prompts for students requiring additional structure (e.g. “What materials are you using?” “How does this help the environment?”).
• Visual learners can access a visual prompt board with various sustainable materials and ideas.

3. Prototype Construction Begins (25 minutes) – Bringing Ideas to Life

• Construction Time: Students begin constructing their prototype using chosen materials and tools. Emphasise safe tool use and effective collaboration where working in pairs.
• Encourage iterative creativity – allow students to tweak their design if they discover construction challenges.
• Roaming teacher feedback: Check whether prototypes demonstrate innovation, practicability, and alignment with the original design brief.

🪛 Extension for Advanced Learners:
Encourage high-level thinkers to integrate renewable energy concepts (e.g. mini solar panels, wind-driven movements, water collection features) or design for scale (how might this work in a community setting?).

---

4. Reflection & Peer Feedback (10 minutes) – Sharing Progress

• Students pair up and explain their prototype to a peer using these prompts:
  • “What sustainability issue does your prototype address?”
  • “How is your design environmentally friendly?”
  • “What challenges are you facing or foresee?”
• Ask 2–3 volunteers to share standout designs with the class under the visualiser or display table.

🧠 Teacher Prompt: “What was something you changed during the build? Why did you make that change?”
Encourage reflective thinking and real-world problem solving.

---

Assessment Opportunities:

• Informal assessment via observation during sketching and prototyping—look for purposeful design decisions aligned with sustainability goals.
• Students’ verbal reflections provide insight into their problem-solving skills and understanding of materials' environmental impact.

---

Differentiation Strategies:

Learner Need	Strategy
EAL / Lower Literacy	Use visual representation tools and word banks (e.g. icons for ‘Reduce’, ‘Reuse’, ‘Renewable’)
Visual/Spatial	Offer 3D building examples and encourage model manipulation
Cognitive Support	Provide sentence starters for annotations and construction reflection
Physical Support	Pair for construction or provide tools with ergonomic designs

---

Materials Suggestions:

• Cardboard (pre-cut into shapes)
• Bamboo skewers (blunt ends only for safety)
• Paper clips, string, fabric remnants, aluminium foil
• Small solar-powered toys (for exploring functionality)
• Container lids / yoghurt tubs / bottle caps

---

Extension Activities:

• Design Portfolio Page: Students write a page explaining the purpose and potential impact of their prototype, for inclusion in their sustainability design folio.
• Mini Pitch Video: Advanced students can film a 30-second elevator pitch explaining how their design could help schools, homes or communities embrace sustainability.

---

Closing Thought:

“Sometimes the most powerful inventions start with just scissors, sticky tape, and a student's imagination. Real change begins with one smart and sustainable idea.”

Looking Ahead – Lesson 8 Preview:

In the next and final lesson, students will present their completed prototypes to the class or a panel, explaining their sustainable purpose and reflecting on their design process. They’ll participate in peer feedback and evaluate prototypes using a shared rubric.
