Students will know
- The requirements for NCEA Level 1 Science (4 credits, internal practical investigation).
- How to formulate a clear, testable biological question grounded in an authentic Aotearoa context.
- How scientific investigation aligns with kaitiakitanga (environmental guardianship of our local awa and ecosystems).
Students will demonstrate
- By selecting a practical context and drafting a clear biological investigation question.
- By completing Section 1 of their Level 1 Science Biological Investigation Logbook.
Curriculum alignment
- NZC (2007) · Science · Level 6 · Nature of Science: “Develop an understanding of socio-scientific issues by gathering relevant scientific information in order to draw evidence-based conclusions and to take action where appropriate.”

Science Inquiry Prompt:
"Which of these two statements is a testable biological question?"
A: "Why do plants in our local stream look pretty?"
B: "How does light intensity affect the rate of oxygen bubble production in local aquatic plants?"
Unpack: Statement B is testable because it names a specific environmental factor (light intensity) and a measurable biological response (oxygen bubble rate per minute). Statement A is an opinion.
3 Authentic Investigation Contexts in Aotearoa (15 min)
🌿 Context A: Photosynthesis in Local Awa Plants
Investigate how light intensity or water temperature affects the rate of photosynthesis (bubble production) in aquatic plants (e.g. Elodea or native Myriophyllum).
🌱 Context B: Seed Germination & Soil Moisture
Investigate how soil moisture or salinity affects the germination rate of harakeke (Phormium tenax) or crop seeds over a 10-day period.
🍞 Context C: Yeast Cellular Respiration
Investigate how temperature or sugar concentration affects CO₂ gas production in yeast, connecting to fermentation in traditional rongoā and food preservation.
📁 Biological Investigation Logbook — Section 1: Biological Question & Context
Students open their Level 1 Science Logbook and complete Section 1:
Section 1 Requirements:
1. Chosen Biological Context: State which context you will investigate (Photosynthesis, Germination, or Respiration).
2. Investigation Question: Write a precise question in the form: "How does [Independent Variable] affect [Dependent Variable] in [Organism]?"
3. Kaitiakitanga Rationale: Explain why understanding this biological process matters for managing local stream health or biodiversity in Aotearoa.
