💧 Wai — Water is Life
"Ko au te wai, ko te wai ko au" — I am the water, the water is me.
For Māori, water is not just a resource — it is a taonga (treasure) with its own mauri (life force). Rivers, lakes, and oceans have their own whakapapa (genealogy) and are related to the people who live alongside them.
Understanding the water cycle through both science and mātauranga Māori gives us a richer picture of this precious resource.
🔄 The Four Stages of the Water Cycle
1. Evaporation
Te Kohu
The sun heats water in oceans, lakes, and rivers. Water turns from liquid to water vapor (gas) and rises into the air.
2. Condensation
Te Tōtōnga
As water vapor rises, it cools and condenses into tiny water droplets that form clouds (kapua).
3. Precipitation
Te Ua / Te Huka
When water droplets in clouds become heavy, they fall as rain (ua), snow (huka), sleet, or hail.
4. Collection
Te Kohikohi
Water collects in oceans (moana), rivers (awa), lakes (roto), and underground (puna). The cycle begins again.
🌿 Two Ways of Knowing
| Scientific Understanding | Mātauranga Māori |
|---|---|
| Water molecules change state (solid, liquid, gas) | Water has mauri (life force) that transforms but never disappears |
| The cycle is driven by the sun's energy | Tama-nui-te-rā (the sun) and Tangaroa (god of the sea) work together |
| Water is a resource to be measured and managed | Water is a relative (whanaunga) to be respected and protected |
| Pollution can be measured in parts per million | Pollution diminishes the mauri of the water |
| Focus on physical processes | Focus on relationships and responsibilities (kaitiakitanga) |
Both ways of knowing are valuable and can work together to help us understand and protect water.
📝 Activity 1: Label the Cycle
Use these words to label the water cycle: evaporation, condensation, precipitation, collection
Draw arrows to show the direction water moves through the cycle.
📝 Activity 2: Think About It
a) The water you drink today may have once been in a dinosaur! Explain why this is possible.
b) Why is the water cycle called a "cycle"?
c) What would happen if evaporation stopped?
📝 Activity 3: Kaitiakitanga — Guardianship
As kaitiaki (guardians), we have a responsibility to protect water.
a) Name three ways humans can harm the water cycle:
b) Name three ways you can help protect water in your community:
c) Why might understanding both scientific and Māori perspectives help us care for water better?
🏞️ Your Local Water
Research the waterways near your school or home:
Name of local river/stream/lake:
Māori name (if you can find it):
Which iwi or hapū has connections to this water?
What is the health of this waterway? Is it clean? What affects it?
📚 Kupu Māori — Vocabulary
👩🏫 Teacher Notes
Curriculum: NZC Level 3-4 Science — Planet Earth and Beyond
Key Ideas:
- Water cycles continuously through evaporation, condensation, precipitation, and collection
- Scientific and mātauranga Māori perspectives can complement each other
- Humans have responsibilities as kaitiaki of water
Extension: Investigate a local water issue; conduct a stream health survey; research iwi perspectives on local waterways.
Hononga Marautanga · Curriculum Alignment
Level 3–4: Investigate how living and physical systems work; understand relationships between organisms and their environments; collect, interpret, and evaluate scientific evidence to explain natural phenomena.
Level 3–4: Understand how human activity affects natural environments; explore the connection between ecological health and community wellbeing; recognise the role of cultural knowledge in environmental decision-making.

Aronga Mātauranga Māori
Mātauranga Māori is a sophisticated knowledge system built through centuries of careful observation, hypothesis, testing, and refinement — the same processes that define scientific inquiry. Māori knowledge of ecology, weather patterns, seasonal change, and animal behaviour guided sustainable resource management for generations before Western science arrived in Aotearoa. Understanding science through a dual-knowledge lens — bringing mātauranga Māori and Western science into dialogue rather than hierarchy — produces richer, more contextually grounded understanding. The concept of kaitiakitanga reminds us that scientific knowledge carries obligations: understanding how natural systems work means accepting responsibility for how we treat them.

📋 Teacher Planning Snapshot
Ngā Whāinga Ako — Learning Intentions
Students will explore awa (river/water) as taonga, developing understanding of kaitiakitanga through water guardianship — connecting indigenous environmental knowledge with scientific and civic action.
Ngā Paearu Angitū — Success Criteria
- ✅ Students can explain the significance of awa in te ao Māori and their local community.
- ✅ Students can identify actions that reflect kaitiaki responsibilities for local waterways.
Differentiation & Inclusion
Scaffold support: Provide sentence starters and graphic organisers for inquiry tasks. Offer entry-level observation activities and extension challenges involving community advocacy or environmental data analysis.
ELL / ESOL: Pre-teach key te reo Māori terms (awa, kaitiaki, wāhi tapu, tūrangawaewae). Allow visual and diagrammatic responses. Bilingual glossaries strongly recommended.
Inclusion: Connect to students' own waterways and places of belonging. Neurodiverse learners benefit from structured field investigation templates and clear step-by-step inquiry protocols.
