Te Hurihanga Wai
The Water Cycle • Two Ways of Knowing
💧 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.
