Understanding Recyclables

Overview

This 40-minute lesson is the second in the unit "Crafting a Sustainable Future" for Year 7-8 students in New Zealand. It focuses on helping students identify different types of recyclable materials through a hands-on sorting activity and understanding the recycling process and its contribution to sustainability. This lesson aligns directly with the New Zealand Curriculum Refresh by integrating competencies and values such as participating and contributing, and relating to others, while meeting relevant learning objectives from social sciences and technology domains within the curriculum.

Lesson Structure (40 minutes)

Time	Activity	Details
0-5 mins	Introduction and Linking Previous Learning	Briefly review key points from Lesson 1 ("Our Waste Footprint"). Set the lesson aim. Engage students with a question: "Why is recycling important for our future?"
5-10 mins	Pre-Activity Discussion: Types of Recyclables	Teacher-led discussion introducing major recyclable materials: paper, plastic, glass, metal, organic waste. Use visuals (real items or images) to support recognition.
10-25 mins	Hands-On Sorting Activity	Divide class into 5 groups (~5 students each). Each group receives a mixed box of recyclable and non-recyclable items (real/simulated). Groups sort items into correct categories. Circulate to prompt discussion and ask guiding questions: - How do you know this belongs in this category? - What happens to this material in the recycling process?
25-30 mins	Group Share and Class Discussion	Groups present one interesting thing they learned about their recyclable material and its impact on sustainability. Teacher reinforces recycling processes linked to sustainability benefits.
30-35 mins	Impact Reflection and Questioning	Reflect on how recycling impacts the environment and community. Ask: "What can we do at school and home to ensure our recyclables are correctly sorted?" Facilitate student-generated ideas.
35-40 mins	Lesson Wrap-Up and Next Steps	Summarise key learnings. Highlight importance of responsible waste management. Preview Lesson 3 focus (reducing waste). Assign a small home task: notice recyclables at home and bring an example or photo to next class.

Resources Needed

• Mixed recyclable waste items (clean) or realistic images/cards representing paper, plastic, glass, metal, organics, and non-recyclable waste.
• Sorting bins/boxes labelled clearly.
• Visual aids poster explaining recycling processes of each material.
• Reflection worksheet or journal for students (optional).

---

Assessment and Evidence of Learning

• Formative: Observe students during the sorting activity for accurate categorisation and reasoning.
• Class Discussion: Listen for students' explanations about recycling processes and sustainability impacts.
• Reflection: Oral or written reflections on personal and collective responsibility for recycling.
• Home Task: Bring an example or photo - evidences connection to home environment and ongoing learning.

Differentiation and Inclusive Practice

• Provide visual supports and bilingual labels if helpful for English Language Learners.
• Facilitate collaboration by mixing abilities within groups so students can support one another.
• Offer scaffolding questions during activities for students needing extra support.
• Provide extension by encouraging some students to research one specific recyclable in more depth.

Teacher Tips to Impress

• Use real recycled products when possible to make learning authentic and engaging.
• Introduce a "recycling detective" role in each group to encourage leadership and critical questioning.
• Connect learning to local community recycling initiatives and iwi perspectives about kaitiakitanga (guardianship).
• Use simple diagrams or flowcharts to represent the recycling process, linking visual literacy with science and technology learning.
