Ask students to write down three things they expect to see at the unprotected site and three things they expect to see at the marine reserve. These predictions become the first point of comparison when they surface.
Look for fish (species, numbers, size), invertebrates (kina, sea stars, crabs), seaweed and kelp, water clarity, and any signs of disturbance or human activity. Each student or pair keeps a tally. Note what is absent as well as what is present.
Back on shore between the two snorkel sessions, ask students to share one unexpected thing from the first site. Do not reveal the reserve site yet. Let students predict: "What do you think we will find at the next site that was missing here?"
Use exactly the same tally sheet as the first site. Fish species and numbers, invertebrates, seaweed, water clarity. The comparison only works if the observation method is consistent between sites.
Snapper (tāmure) are a key indicator species for marine reserve health. Their size and abundance increase significantly inside protected areas. Kīnaki (kelp) coverage is another indicator. Nudibranch variety tells a story about ecosystem complexity. EMR coordinators will help students identify what they are seeing.
Before leaving the water site, ask each student to name the single biggest difference they noticed between the two sites. Capture these on a shared list. This immediate, unprocessed response is the most honest record of what the experience produced.
EMR describes its goal as creating kaitiaki Tangaroa, guardians of the sea. Ask students: what would it mean to act as a guardian of this place? What would you do differently? What would you ask others to do? This question is the bridge to Stage 5.
The EMR programme is built on a single, powerful comparison. These are the things students are looking for and thinking about at both sites.
In a fully protected marine reserve, snapper (tāmure) grow larger and are more numerous than in adjacent unprotected areas. Research at the Poor Knights Islands confirmed significant increases in snapper abundance and biomass after full reserve status was established in 1998. Students seeing large snapper inside a reserve are seeing the direct result of protection.
Marine reserves protect the entire food web, not just target species. Gorgonian fans, sponge gardens, nudibranchs, and invertebrate communities that are absent or rare in fished areas recover steadily under protection. The variety of what students see underwater is itself a measure of ecosystem health.
Ngātiwai, the tangata whenua of the Poor Knights and much of the Northland coast, hold the moana as central to their identity. "Although you stand on land, you stand also in the sea" is the whakatauaki attributed to their ancestor Manaia. The EMR programme explicitly incorporates kaitiakitanga and mātauranga Māori perspectives on marine guardianship alongside the science of marine reserve ecology.
A marine reserve is a no-take zone: no fishing, no collecting, no disturbance of marine life. The Marine Reserves Act 1971 underpins all NZ marine reserves. Students who have seen both sides of that boundary understand conservation policy through their own observation rather than through a textbook description.
Each year, Mountains to Sea Conservation Trust and Dive! Tutukaka run an annual competition for schools participating in the EMR programme. Students submit marine conservation action projects, and the best projects win a full-day snorkel and dive trip to the Poor Knights Islands Marine Reserve, 22 km off the Tutukaka Coast. The competition has run since 2002 and is now in its third decade. It is the most significant student marine conservation prize in New Zealand.
The Poor Knights Islands Marine Reserve is one of the world's great marine environments, rated by Jacques Cousteau as one of the top ten dive sites on the planet. Its waters sit at the convergence of subtropical and temperate currents, supporting over 152 fish species. Rikoriko Cave is the largest measured sea cave in the Southern Hemisphere. The islands are wāhi tapu to Ngātiwai and no landing is permitted, so the entire experience is from the water. Students who have been there describe it as unlike anything else they have seen in New Zealand.
The competition is open to schools participating in the EMR programme. Student action projects are submitted for judging. Projects are assessed on the quality of the conservation action taken, the thinking behind it, and the connection to what students observed during their EMR snorkel experiences. Past winning projects have included storm water filtration designs, plastic reduction campaigns, and letters to Members of Parliament.
These prompts work best when used before the in-water experience as preparation, and after it as reflection. Students who have snorkelled at both sites have something AI does not: direct observation data from both sides of a conservation boundary. The AI prompts are most powerful when students are using their own field observations to evaluate AI outputs, not the other way around.
Before snorkelling, ask a gen AI chatbot: "What is a marine reserve and why do fish grow bigger inside one?" Write down its answer. After snorkelling at both sites, look at the answer again. Does what you saw in the water match what the AI said?
Draw or photograph one creature you saw at each site. Ask a gen AI chatbot: "What is this animal and what does it eat?" Then ask: "Would this animal be found in a marine reserve or outside one?" Check its answer against what your EMR coordinator told you.
Tell a gen AI chatbot: "We snorkelled at two places. At the first place we saw [your list]. At the marine reserve we saw [your list]. Why were they different?" Does its explanation match what your EMR coordinator told you?
Ask a gen AI chatbot: "If you could create a new marine reserve anywhere in New Zealand, where would it be and why?" Then think about your own answer. Where would you choose? What would you need to know to make that decision?
Ask a gen AI chatbot to explain how a marine reserve changes fish populations over time: "What happens to snapper abundance and size when an area becomes a no-take marine reserve, and how long does it take?" Compare its answer to the data from the Poor Knights Islands post-1998 research. Does the AI account match the evidence?
The EMR programme includes both kaitiakitanga and the Marine Reserves Act 1971 as frameworks for marine protection. Ask a gen AI chatbot: "What is the difference between protecting the ocean through kaitiakitanga and protecting it through legislation?" Evaluate the response. What does it understand well? What does it flatten?
Using the tally sheet from your two snorkel sites, ask a gen AI chatbot: "We counted [your data] at an unprotected site and [your data] at a marine reserve. What does this difference tell us about the effectiveness of marine protection at our sites?" Critically assess whether its analysis matches your EMR coordinator's interpretation.
Ask a gen AI chatbot to help you identify a marine conservation problem in your local area: "What are the main threats to marine environments near [your location] and what could a group of secondary school students realistically do to address one of them?" Use its response as a starting point, then check it against local knowledge from your teacher, your EMR coordinator, or local iwi.
Research the evidence base for marine reserve effectiveness using at least two peer-reviewed or government sources (NIWA and DOC are good starting points). Then ask a gen AI chatbot the same question. Produce a critical comparison: where does the AI's account hold up against the evidence? Where does it oversimplify, omit key findings, or misrepresent the complexity of the research?
The EMR programme incorporates mātauranga Māori perspectives on marine guardianship. Ask a gen AI chatbot: "How does mātauranga Māori understanding of the moana compare to a Western scientific framework for marine conservation, and where have the two been brought into productive collaboration in New Zealand?" Critically evaluate the response against what you encountered in the EMR programme and any iwi sources your teacher provides.
New Zealand's Marine Reserves Act 1971 is one of the oldest marine protection laws in the world. Ask a gen AI chatbot to outline its key provisions and limitations. Then research whether the Act has been reviewed or reformed and what conservation organisations have said about its adequacy. Write a short policy brief: is the Act fit for purpose in 2026, and what would strengthen it?
The EMR comparison method (snorkel at unprotected site, then marine reserve, using consistent observation protocol) is a form of citizen science data collection. Ask a gen AI chatbot: "What makes citizen science data scientifically credible, and what are its limitations compared to professional ecological surveys?" Then evaluate the EMR method against those criteria. What does student-collected comparison data contribute that professional surveys cannot replicate?
| Level | Years 1–6 | Years 7–10 | Years 11–13 |
|---|---|---|---|
| 1 | Student names at least one organism they saw at each site and can say which site had more fish. Understands they snorkelled at two different places and that one is protected and one is not. | Student identifies key indicator species from both sites, notes the difference in abundance and diversity between the protected and unprotected sites, and makes a basic claim about what protection does to a marine environment. | Student produces a systematic comparison of the two snorkel sites using their tally data, identifies indicator species, and links observable differences to the mechanisms of marine reserve protection. |
| 2 | Student explains in simple terms why a marine reserve has more fish: because fishing is not allowed, the fish can grow bigger and there are more of them. Can connect this to something they saw in the water. | Student explains the ecological mechanism connecting no-take protection to increased fish abundance and size, links this to the food web, and identifies at least one way the reserve and non-reserve sites differed in ecosystem complexity beyond fish numbers. | Student constructs a causal account of how marine reserve protection changes an ecosystem over time, drawing on both their field observation data and supporting evidence from NIWA or DOC research. |
| 3 | Student compares what a gen AI chatbot says about marine reserves with what they saw in the water. Can say at least one thing the AI got right and one thing it could not know because it was not there. | Student systematically evaluates AI outputs about marine reserve science against their field observation data and at least one authoritative source. Identifies where the AI is accurate, where it oversimplifies, and what the in-water experience added that the AI could not. | Student produces a structured critical analysis of AI outputs on marine reserve ecology and policy, drawing on field data, peer-reviewed sources, and EMR coordinator knowledge to assess the AI's reliability and limitations in a conservation science context. |
| 4 | Student can describe what being in the water at both sites added that a photograph, video, or AI description could not: the feeling of floating above more fish than they have ever seen, the colour difference, the silence of a healthy reef. | Student articulates what direct in-water observation provided that secondary sources could not: personally collected comparison data, the embodied experience of the difference in ecosystem health, the immediacy of being surrounded by what protection has produced. | Student reflects on what the EMR in-water experience contributes to environmental knowledge that no AI, documentary, or academic paper can replicate, and connects this to the broader epistemological argument for experiential environmental education. |
| 5 | Student identifies one action they will take as a result of the EMR experience. Can say what they will do, who they will tell, and why it matters to them personally. | Student designs and begins implementing a marine conservation action project: a community campaign, a letter to a decision-maker, a school event, or a local environmental intervention. Considers entering the EMR Poor Knights Annual Competition. | Student completes a sustained marine conservation action project grounded in their field observations and research: a policy brief, a community engagement campaign, a citizen science contribution, or a proposal for a new marine protection initiative, with documented evidence of impact or outreach. |
