Week 5 after students have worked with more than one forecast or environmental prediction and need to judge reliability instead of accepting every prediction equally.
Mathematics + science • Years 7-10 • Unit 9 Week 5 evidence review
Use this worksheet to compare environmental forecasts with what actually happened. Students measure how close predictions were, explain why some were stronger than others, and decide how future forecasts can better support local action.
This version is ready to teach immediately. Te Wānanga becomes useful when you want your own class weather logs, NIWA records, council data, or lower-reading comparison prompts inserted.
This rebuild turns the old generic graph page into a real evidence-quality task for environmental prediction.
The companion page makes the mathematics fit explicit around time-series investigation, data communication, and evidence-based judgement rather than treating forecasting as guesswork.
A prediction becomes useful when students can compare it with what actually happened and explain the gap. That helps them decide whether a model, dataset, or observation should shape future action.
Through a mātauranga Māori lens, this also asks how kaitiakitanga shapes cautious decision making: if uncertainty is high, people still need to act carefully to protect taiao and community wellbeing.
Complete the table using classroom, NIWA, local, or school-collected data.
| Forecast or prediction | What was predicted? | What actually happened? | How close was it? | What might explain the gap? |
|---|---|---|---|---|
| Temperature or heat forecast | ||||
| Rainfall or storm forecast | ||||
| River, soil, or ecosystem condition prediction |
Which prediction was closest to reality? What evidence proves that?
Where was the biggest gap, and what may have been missed?
Which source would you trust most next time, and why?
What data, time period, or local factor may have reduced accuracy?
What would make the next prediction stronger?
How could whānau knowledge, school observations, or ngā tohu o te taiao improve the forecast?
Write one sentence that explains how accurate the forecast set was overall and what should change before the next prediction is used for environmental action.
Level 3–4: investigate how the Earth's climate has changed over time; understand how human activity affects ecosystems and atmospheric systems; use evidence to evaluate claims about climate impacts on local environments and communities.
Level 3–4: understand that environmental changes have consequences for communities and future generations; develop the ability to evaluate responses to environmental challenges and propose informed, responsible action.
In traditional Māori environmental knowledge, prediction was not a one-off event — it was a cycle of observation, forecast, action, and return. A tohunga kōrero who made a seasonal forecast would observe whether the signs they read proved accurate, and update their understanding accordingly. This iterative calibration process is exactly what prediction accuracy analysis formalises: make a claim, wait, measure the outcome, evaluate the claim, improve the model. The epistemological logic is the same across both knowledge systems.
As you assess prediction accuracy today, consider what counts as a 'correct' forecast. In mātauranga Māori, a forecast that led to appropriate kaitiakitanga action might be valued differently from one that was numerically precise but failed to prompt protective behaviour. In science, accuracy is measured against observed data. Both measures matter: an accurate forecast that no one acts on is no better than a rough estimate that provokes wise stewardship.
