Waste Cycle Journey

Overview

In this lesson (3 of 8), students watch an educational video about the waste cycle journey. After watching, they will complete a related worksheet to reinforce their understanding of the waste cycle and sustainability concepts. This approach focuses on video-based learning and worksheet activities rather than a simulation.

Learning intentions

Students will:

• describe the journey of recyclable materials from collection to processing and reuse
• identify design criteria for making solutions more sustainable (including reducing waste)
• evaluate a recycling pathway idea by checking it against criteria and suggesting a simple improvement

Success criteria

Students can:

• explain at least three steps of a recycling journey in order
• use class-made design criteria to say what works and what needs improvement
• revise their recycling pathway actions or materials to better meet sustainability needs
• participate safely and respectfully in group simulation roles

Curriculum links

• Technologies: use given or co-developed design criteria including sustainability to evaluate design ideas and solutions - Technologies: select and use materials, components, tools, equipment and techniques to safely make designed solutions through safe use of simulation props and cooperative roles
• Digital Technologies link (brief, optional connection): implement simple algorithms as visual programs involving control structures and input by modelling “if/then” decisions during the simulation - Technologies context: examine factors including sustainability that impact on products/services/environments to meet community needs through the recycling pathway scenario ## Lesson structure (45 minutes)

1. 0–5 min · Hook: “Next stop!” Teacher holds up three real or picture cards (plastic bottle, paper, aluminium can) and asks: “What happens next after we put it in the recycling bin?” Students turn-and-talk, then share one possible step.

2. 5–12 min · Direct teach: The waste cycle basics Teacher draws a simple class diagram: Collect → Sort → Process → New product (or Reuse) and notes that not everything placed in recycling can be reused. Students help complete a short “before/after” sentence frame: “After collection, recyclables are…”.

3. 12–25 min · Simulation: “Act it out!” Teacher explains stations around the room: Collection Point, Sorting Table, Processing Area, and “New Product” display. Students are assigned roles in groups of 3–4 (e.g. Collector, Sorter, Processor, Quality Checker, Carrier). Each group receives 6–8 “material tokens” (cards or paper shapes).

• Teacher calls out scenarios: “A paper token with food on it enters recycling” or “An aluminium token has a label still attached.”
• Sorting rules are co-created on the spot using the class design criteria (e.g. “Reduce waste”, “Supports recycling”, “Low harm/safety”, “Fair access for all to understand”).
• Students physically move tokens through stations, then pause at Quality Checking to decide if the token keeps going or is sent to “Landfill/Not accepted”. Teacher circulates, using prompts: “Which criterion does this choice meet?” “What waste might be created if sorting is wrong?”

4. 25–34 min · Co-developed criteria check Teacher displays the class’s sustainability design criteria (from the unit so far) as a simple checklist poster. Students, still in groups, choose one recycling pathway they acted out and rate it:

• Meets criteria well (tick) or Needs improvement (circle)
• Write one reason and one change they would make.

5. 34–42 min · Share and revise Each group shares one “what we’d change” revision. Teacher records common improvements (e.g. clearer sorting guidance, better container choices, reducing contamination, using repair/reuse where possible). Students listen and add one additional idea to another group’s revision using a sentence starter: “Another way to improve this is…”

6. 42–45 min · Exit ticket: “One step + one criterion” Students complete a quick exit ticket:

• “One step in the waste cycle is…”
• “The recycling pathway improves sustainability because it…” (choose one criterion from the checklist)

Resources

• Educational video about the waste cycle journey (suggested video search: "waste cycle journey for kids")
• Waste cycle worksheet for students to complete after watching the video
• Clipboard/paper for worksheet completion
• Exit ticket slips and pencils
• Safety reminder visuals for classroom behavior
• Design criteria checklist poster (teacher-made from class)

Assessment

• Formative: observe group decision-making during sorting and ask targeted questions about criteria and sustainability
• Formative: check group criteria ratings and the clarity of “reason + change” responses
• Summative-in-mini: review exit tickets to confirm understanding of recycling steps and use of at least one sustainability criterion

Differentiation

• Support: provide sentence starters for exit ticket and evaluation (e.g. “This meets the criterion because…” / “We would improve it by…”)
• Support: pre-assign roles with clear responsibilities and offer a “job helper” card for students who need extra structure
• Extension: challenge groups to propose a new sorting rule or question they would add to improve outcomes (e.g. “If there is food residue, then…”)
• EAL/SEN: use visuals for criteria and station signs; allow oral responses if writing is a barrier, with teacher scribing brief group ideas
