Ripple Web Impact

Overview

Today students explore how one small decision can affect people and the environment over time. They will build a “ripple effect” web using a ball of wool, then connect their thinking to being kaitiaki (guardians) and taking care of Aotearoa’s environment.

Learning intentions

• WALT explore how historical and environmental changes can happen because of people’s actions.
• WALT explain that decisions can have “ripple effects” that impact others, including living things.
• WALT connect kaitiakitanga to actions we can take to care for our local environment.
• WALT use evidence from our activity to justify our ideas.

Success criteria

• I can describe how one action (e.g., dropping rubbish) can affect people and the environment.
• I can identify multiple ripple effects and explain how they connect.
• I can link kaitiakitanga to at least two actions we can practise at school/home.
• I can listen respectfully and contribute an impact to the shared web.

Curriculum links

• Social sciences, History: New Zealand History — consider changes to environments over time caused by people’s actions and choices.
• Social sciences — kaitiakitanga and care for the environment through local, everyday decision-making.
• Developing key competencies: Thinking (explaining cause and effect), Participating and contributing (sharing ideas respectfully), Relating to others (working safely in a circle), Communicating (using evidence-based statements).

Lesson structure (25 minutes)

1. 0–3 min · Warm-up question. Teacher reads a short prompt (no long story yet): “What would happen if one person drops one piece of rubbish and no one picks it up?” Students think-pair-share for 30 seconds, then share 1 idea.

2. 3–8 min · Story and set-up. Teacher tells a brief scenario: a student drops a piece of rubbish; it moves through pathways (ground → stormwater/river/sea → animals/people). Students sit in a circle and listen for the “first action” and its possible impacts.

3. 8–15 min · Wool web ripple effect. Teacher holds the wool ball and starts with the first impact: “This rubbish is now on the ground.” Student task: when teacher names an impact (small or big), the student who receives the wool must hold one string segment and add a connected impact using a sentence frame: “Because of that, … (impact on environment/people/animals).” Continue until the web forms. Teacher observes and ensures every student contributes at least once (or with a partner support if needed).

Student sentence frames (on board):

• “Because of that, the environment…”
• “This affects people/animals by…”
• “It shows kaitiakitanga when we…”

4. 15–20 min · Connect to kaitiaki. Teacher asks: “What does kaitiakitanga look like when we notice mess at school?” and “How can we reduce harm?” Students respond with “Now we should…” statements, and teacher records 2–3 class commitments on a chart.

Quick discussion prompts:

• “What impact would happen if we acted straight away?”
• “Who benefits when we take care of the environment?”

5. 20–24 min · Quick check (exit ticket). Students complete a one-minute written response (or oral for support):

• “One ripple effect from dropping rubbish is…”
• “A kaitiaki action I will practise is…”

6. 24–25 min · Wrap. Teacher thanks students, briefly celebrates contributions, and reads 2 exit-ticket examples (with permission).

Resources

• Ball of wool (enough to create a web)
• Story prompt cards or teacher script (short scenario)
• Chart paper/whiteboard and marker
• Sentence starters on board
• Exit ticket slips (paper or notebook page)
• Timer
• Optional: gloves or a “rubbish” prop for the initial story moment

Assessment

• Formative during the wool web: listen for clear cause-and-effect links and connected impacts.
• Formative questioning in the kaitiaki discussion: check students can explain why actions matter.
• Exit ticket: verify students can state a ripple effect and a kaitiaki action.

Differentiation

• Support: provide sentence frames, allow a student to answer with a partner, and offer an “impact bank” word list (e.g., animal, water, people, clean-up, pollution, harm, safety).
• Support for multilingual learners: accept first-language oral responses; students then choose one sentence frame to copy/complete in English.
• SEN considerations: assign predictable turns (e.g., one impact card per student) and reduce pressure to speak—students can point to a written impact option.
• Extension (advanced learners): ask students to add a “time link” (“right now / later / long-term”) and include two connected impacts (environment + community). They can also propose one class rule and justify it with evidence from the web.

Extension (optional)
