🏭 Week 3: Human Impacts & Actions

Students analyse how human activities positively and negatively impact our waterways. Through cause-and-effect mapping and role-play, they identify realistic actions to improve awa health.

Focus Question

What are the causes of pollution in our awa, and what can we do to help?

🎯 Learning Intentions

  • Identify human activities that harm or help the awa
  • Match causes to effects and suggest practical actions
  • Use mapping tools to plan environmental solutions

✅ Success Criteria

  • I can complete a cause -> effect -> action chain
  • I can explain a local human impact on our awa
  • I can suggest one realistic action for school or home

🗣️ Kupu / Vocabulary

  • parahanga (pollution), para (rubbish)
  • rerenga wai (runoff), take (cause)
  • hua (effect), rongoā (solution)

📚 Curriculum Links

  • Social Science: Place and Environment
  • Health & PE: Community Health
  • Science: Nature of Science

Ngā Mahi - Week 3 Activities

1. Impact Analysis: Stormwater vs Wastewater (15 mins)

Activity: Explore common pollutants and how they enter our waterways through infrastructure like drains and runoff.

  • Gallery Walk: Compare photos of drains, litter, and planting
  • Learn: Stormwater vs Wastewater — where does the water go?
  • Identify never-goes-down-the-drain items: soap, paint, oil

Stormwater Explained

2. Planning Solutions: Cause & Effect (25 mins)

Activity: In pairs, use the Cause -> Effect -> Action Organiser to map out 2-3 impact chains.

  • Example: Soap in drain (Cause) -> Dead fish (Effect) -> Car wash on grass (Action)
  • Link findings from Week 2 (pH/litter data) to justify actions
  • Groups share their "strongest" action with the class

3. Voices of the Awa: Role-Play (20 mins)

Activity: Students take on roles as the Awa, a Native Fish, a Local Farmer, or a Kaitiaki to explore different perspectives on water health.

  • Use Interview Prompts to guide the dialogue
  • "The Awa says: 'I feel choked with silt today...'"
  • Kaitiaki responds with a solution or action

💡 Differentiation Strategies

  • Scaffolding: Provide pre-filled causes or effects for matching
  • Support: Offer sentence stems: "If people ___, the awa ___, so we can ___."
  • Extension: Research the path of stormwater from your school playground to the sea

Curriculum alignment

  • Ecosystems — Knowledge: Human activity and technology impact the environment.
  • Body Systems — Knowledge: Some animals, like fish, respire using gills, which take oxygen out of water.

📋 Teacher Planning Snapshot

🌊 Kaitiakitanga this week — Cause and effect is also a question of who bears it

This week the kaitiakitanga is responsibility. Every cause→effect chain has people at both ends. What this changes: when ākonga complete a chain, they add one more link — who benefits from the activity, and who lives with the effect downstream. That is the difference between an environmental fact and a kaitiaki judgement.

Unit-wide success criteria

Assess this week against its own criteria above. The unit-wide criteria live once on the unit overview — they are not repeated here, so nobody marks the week against the wrong list.

Differentiation & Inclusion

Scaffold support: A cause-and-effect strip with the effect supplied so ākonga work backwards to the cause. Extension: find a real local consent or council report about the awa.

ELL / ESOL: Impact vocabulary (sediment, runoff, discharge) taught against photographs of the actual awa before any reading.

Inclusion: This week can name harm caused by families' own farms or workplaces. Discuss practices and systems, never individual households.

🌿 Mātauranga Māori Lens

If an awa is a tupuna, then harm to it is harm to a relative — which is why kaitiakitanga frames pollution as an obligation breached, not merely a standard exceeded. Note that a discharge can be entirely lawful and still be a breach in these terms. That tension is the week's real question, and it is not resolved by picking one framework.
