Lesson Overview

Time	Activity	Description
5 min	Introduction and Engagement	Briefly introduce the new unit “Waste Wise: Crafting Sustainability.” Explain the importance of caring for the planet through mindful use of materials and waste.
10 min	Video Presentation	Show a short, age-appropriate video explaining waste reduction, reuse, and recycling, highlighting how these actions help the planet. Accompany with simple questions.
15 min	Group Discussion	Facilitate a guided discussion with students about what they learned from the video. Ask questions like: “Why is it important to reduce waste?” and “How can we reuse things?”
10 min	Think-Pair-Share Activity	Students think individually, then share with a partner examples of how their families reduce, reuse, or recycle at home or school. Share some responses with class.
5 min	Recap and Reflection	Recap key concepts and reasons why sustainable habits matter. Encourage students to think about what they can do in the coming week to practice waste wise actions.

Detailed Lesson Plan

1. Introduction and Engagement (5 minutes)

• Greet students and introduce the unit “Waste Wise: Crafting Sustainability.”
• Briefly explain that waste and how we handle it is important for looking after our planet.
• Use simple language: “Waste reduction means making less rubbish. Reuse means using things again instead of throwing them away. Recycling means turning old things into new things.”

2. Video Presentation (10 minutes)

• Show a short video (3-5 minutes) carefully selected for Year 3 students that explains waste reduction, reuse, and recycling with clear visuals and examples relevant to Australian context.
• Pause occasionally to ask comprehension questions: “What does recycling mean?” “What can we do to reduce waste?”
• Reinforce key vocabulary and encourage student questions.

3. Group Discussion (15 minutes)

• Use open-ended questions to stimulate talk:
• Why do you think it’s important to reduce waste?
• Can you think of ways your family or school reuses items?
• What kinds of things do we recycle?
• Write students’ ideas on the board under three headings: Reduce / Reuse / Recycle.
• Support participation by prompting quieter students gently.
• Emphasise how these actions help protect animals, keep the environment clean, and save resources.

4. Think-Pair-Share Activity (10 minutes)

• Ask students to think quietly about: “What do you or your family do to reduce, reuse, or recycle?”
• Pair students up to share their ideas and listen to their partner.
• Invite a few pairs to share interesting examples with the whole class.
• Highlight simple everyday actions (e.g., using a reusable water bottle, donating old clothes, recycling paper).

5. Recap and Reflection (5 minutes)

• Review the key points: definition of reduce, reuse, recycle and their importance.
• Encourage students to choose one thing to try at home or school this week to be waste wise.
• Ask for volunteers to share what they will do.
• Close by affirming their role in helping care for the planet.

Assessment and Evaluation

• Formative Assessment: Teacher observation during discussion to assess understanding of sustainability terms and concepts.
• Participation: Note contributions during think-pair-share indicating ability to connect concepts to personal experiences.
• Exit Question: Students verbally share one thing they learned about waste wise behaviour and why it matters.

---

Resources and Materials

• Age-appropriate educational video on waste reduction, reuse, and recycling (select one aligned with Australian environment if possible).
• Whiteboard or chart paper and markers for brainstorming.
• Think-pair-share prompts written clearly on the board or paper.
• Optional: printed images or flashcards of items that can be recycled or reused.

Teacher Notes and Tips

• Use simple and clear language suitable for Year 3 listening and speaking levels.
• Engage students with enthusiasm, linking sustainability to their everyday lives.
• Acknowledge and affirm local examples of sustainability students may share.
• Manage time tightly to include all parts without rushing to ensure comprehension and reflection.
• This lesson lays a foundation for future design and technologies activities focused on creating sustainable solutions.

This lesson aligns with the Western Australian Curriculum for Design and Technologies that encourages exploration of sustainability factors impacting community needs and design decisions for Year 3 and 4 students. It integrates general capabilities such as critical thinking and ethical understanding through interactive and reflective activities.
