📚 Lessons / Ngā Akoranga — Core Arc (6 lessons)
This unit ships as two self-contained teaching arcs. The core arc below is the default: six fully-resourced lessons built around a school-grounds field study, the 1080 debate, restoration planting, and a conservation campaign. A 10-lesson field-journal arc is available as an alternative for classes that want a longer sequence built around an assessed Ecology Field Journal — see Alternative Arc further down this page. Teach one arc or the other, not both: they cover the same ground at different depths.
What is an Ecosystem? Mauri
Biotic and abiotic factors audited outdoors in the school grounds, and the interactions between them read through mauri.
Biodiversity & Endemism
Why Aotearoa has unique species and what threatens them.
Field Study - Rangahau Taiao
Conducting real biodiversity surveys and analysing ecosystem health.
Human Impact & Conservation
Analysing threats to NZ ecosystems and conservation strategies.
Restoration & Kaitiakitanga
Ecological restoration through Māori guardianship principles.
Guardians of the Future
Synthesising learning into conservation action campaigns.
📄 Resources / Ngā Rauemi
These resources support the core arc. All except the Ecosystem Audit Worksheet are maintained in the companion unit Year 9: Aotearoa's Living Landscapes and open there — same handouts and rubrics, kept in one place so updates land once.

Kaiako Planning Snapshot
Ngā Whāinga Akoranga — Learning Intentions
- Describe the structure and function of local NZ ecosystems using correct scientific vocabulary and evidence from field observation.
- Explain how human activity affects ecosystem stability and biodiversity, using data and examples from Aotearoa.
- Apply kaitiakitanga values to evaluate conservation and restoration strategies, linking mātauranga Māori with contemporary ecological science.
- Communicate ecological findings and conservation recommendations in a range of formats (field report, persuasive letter, campaign).
Paearu Angitu — Success Criteria
- I can identify biotic and abiotic factors in a local ecosystem and describe their interactions.
- I can explain at least two threats to NZ biodiversity and evaluate the effectiveness of conservation responses.
- I can connect the concept of kaitiakitanga to a specific ecological practice (e.g., rāhui, pest control, restoration planting).
- I can present my findings clearly, using evidence and acknowledging uncertainty in my data.
Teacher Planning Snapshot
- Year level: Year 9 | Duration: 6 lessons (core arc) or 10 lessons (field-journal arc) | NZC Level 5 (Science: Living World — Ecosystems)
- Curriculum alignment: Te Mātaiaho Science — Phase 4 — Ecosystems strand; practices and knowledge objectives including constructing models, interpreting data, and evaluating human impact. Integrates The Arts and Social Sciences through campaign and action-learning contexts.
- Mātauranga Māori: Kaitiakitanga is the ethical backbone of this unit — not a supplement. Indigenous ecological knowledge (ngā tohu o te taiao, rāhui, mauri) is positioned as parallel and complementary to Western scientific methods. Whakapapa frames ecosystem interconnection. Tikanga guides fieldwork protocols and species respect. Whanaungatanga is embedded in the Science Wānanga and group restoration projects.
- Entry support: Pre-teach core vocabulary (biotic, abiotic, biodiversity, endemic) with visual anchors and te reo glossary. Use physical food-web cards before diagram work. Scaffold field data sheets with sentence starters.
- On-level: Students follow the full 6-lesson sequence with standard handouts. Field study includes quadrat surveys and iNaturalist NZ data collection. Assessment includes field report and persuasive letter.
- Extension: Students design their own restoration proposal with budget, species selection, and a mātauranga Māori rationale. Compare indigenous and Western ecological frameworks in a structured academic discussion.
Inclusion and Accessibility
- ESOL / ELL: Bilingual key-concept cards (English/te reo Māori). Field data sheets use visual prompts. Partner fieldwork reduces written output pressure during observation phase.
- Accessibility: Outdoor fieldwork adapted for mobility needs (boundary-based observation option). Digital alternatives to physical field surveys available via iNaturalist and Google Street View ecological contexts.
- Neurodiverse learners: Predictable lesson structure (hook → investigation → share). Visual ecosystem diagrams before written explanation. Choice in assessment format where possible.
- Cultural safety: Treat kaitiakitanga as lived knowledge — avoid tokenism. Where possible, invite local iwi perspectives on specific habitats studied. Attribution required when using mātauranga Māori frameworks.
Curriculum alignment
Science / Pūtaiao — Ecosystems (Phase 4 / Years 9–10). Quoted verbatim from the live Te Mātaiaho curriculum; each statement is genuinely taught across this unit's lessons. Per-lesson claims sit on each lesson page.
Reading the references below: this unit carries two arcs that are both numbered from 1 — a six-lesson core arc (What is an Ecosystem? → Guardians of the Future) and a ten-lesson field-journal arc. Every reference below is to the core arc, and names the lesson so it resolves from either.
"Biotic and abiotic factors in ecosystems can affect the distribution and abundance of organisms; changes in one part can affect the balance and wellbeing of the whole system (e.g. new predator or pathogen, amount of rainfall, removal of trees, hunting)."
How the unit teaches this: Core arc Lesson 1 What is an Ecosystem? and Lesson 3 Field Study – Rangahau Taiao — the schoolyard ecosystem audit and the quadrat field study, where ākonga measure abiotic factors and compare biodiversity between microhabitats.
"Interpreting data (e.g. graphs, maps) to evaluate how human activity (e.g. agriculture, resource extraction) influences ecosystem stability and biodiversity"
How the unit teaches this: Core arc Lesson 4 Human Impact & Conservation — ākonga graph possum-pressure data from the impact lab and analyse before/after landscape change.
"Ecosystems can usually regenerate naturally, and humans can support this through conservation and restoration."
How the unit teaches this: Core arc Lesson 5 Restoration & Kaitiakitanga — the native planting workshop and school restoration proposal.
"Indigenous knowledge systems, such as mātauranga Māori, are often founded on long-term observations of environmental patterns. For example, ngā tohu o te taiao can be used to monitor seasonal changes and ecosystem health."
How the unit teaches this: Core arc Lesson 3 Field Study – Rangahau Taiao and Lesson 5 Restoration & Kaitiakitanga — maramataka, indicator species and rāhui are taught alongside the field methods they parallel. (In the field-journal arc, rāhui is taught in its own Lesson 5, Kaitiakitanga & Traditional Māori Resource Management; maramataka and ngā tohu o te taiao are taught in the core arc only.)
"Individually, in communities, or as nations, humans can help protect and restore ecosystems through sustainable practices, including conserving resources, supporting regeneration, and developing alternate methods for resource use."
How the unit teaches this: Core arc Lesson 6 Guardians of the Future — conservation campaigns and personal kaitiakitanga commitments across home, school and community scales.
🔗 Alternative Arc — 10-lesson Field-Journal sequence
The alternative arc runs ten lessons around an assessed Ecology Field Journal — each ākonga's own exercise book, set up in the arc's first lesson and built section by section (trophic pyramids, food webs, pest tracking, quadrat sampling, stream MCI audit, restoration design). Choose it over the core arc when you have the timetable room for a full field-data spine. The ten lessons, in teaching order:
- 📖 Lesson 1: Ecosystems, Biomes & Aotearoa's Biodiversity
- 📖 Lesson 2: Energy Flow & Trophic Levels
- 📖 Lesson 3: Food Chains & Food Webs in NZ Native Bush
- 📖 Lesson 4: Introduced Predators & Invasive Species
- 📖 Lesson 5: Kaitiakitanga & Traditional Resource Management
- 📖 Lesson 6: Field Sampling: Quadrats & Transects
- 📖 Lesson 7: Freshwater Ecosystem Health & Bio-Indicators
- 📖 Lesson 8: Predator Free 2050 & Sanctuaries
- 📖 Lesson 9: Ecological Restoration & Community Action
- 📖 Lesson 10: Ecology Capstone Synthesis & Action

Pedagogical Foundations | Ngā Tūāpou Akoranga
Ecology is the science of relationships — between species, between populations, between organisms and their environments. Three researchers explain why genuine ecological understanding requires more than food webs and population curves.
