Earth, Space, and Big Questions | Te Ao Tūārangi
Earth's systems and the scale of the universe
From local awa to distant galaxies — big questions need models, data, and humility about limits.
Wero — the big question
How do Earth's systems interact — and what does the universe tell us about where we come from?

Earth's Spheres and Matter Cycles
Earth is not one system — it is four spheres exchanging matter and energy, and humans are part of the exchange.
Sphere interactions and matter cycles underpin kaitiakitanga — communities need models that connect whenua, moana, air, and living systems.
You will model sphere interactions, trace matter cycles, and analyse human impacts with systems evidence.
Expanding Universe and Space Scales Investigation
Distances in space are so large that light itself becomes a measuring tape — and the universe is still unfolding.
Cosmology invites humility and evidence — including honouring Beatrice Tinsley's Aotearoa contribution to how we understand galaxies and change.
You will calculate cosmic scales, weigh Big Bang evidence, and communicate vastness without misleading your audience.
What you might make
Maker pathways connect your evidence to a real prototype or build.
- Sensor mount3D print
Hold a probe at a fixed depth or position match your strongest evidence spots
If readings shift with probe position, fixing the geometry makes patterns interpretable.
- 3D-print test piece3D print
Isolate one fair-test comparison with a disposable small print
When one variable dominates your comparisons, printing a test shape keeps other factors steady.
