Lesson 2: Biodiversity & Endemism in Aotearoa

Learning Intentions: We Are Learning To understand why New Zealand has unique species and what threatens biodiversity.

Success Criteria: I can explain endemism, identify threats to native species, and propose conservation solutions.

Starter (15 mins)

Tuatara Time Machine

Show students images of tuatara alongside their ancient relatives and dinosaurs. Ask: "Why does New Zealand have a 'living dinosaur' when nowhere else does?" Introduce the concept of geographic isolation leading to unique evolution.

Key Question: What makes New Zealand's wildlife special compared to Australia or other countries?

Main Activity 1 (20 mins)

Endemic Species Investigation

Students work in pairs using the "Endemic Species Detective" handout to research NZ endemic species. Each pair gets assigned a different species (kiwi, kakapo, tuatara, kokako, giant weta, etc.).

Tasks:

  • Research their species' unique adaptations
  • Find out why it evolved only in NZ
  • Identify current population status and threats
  • Discover any mātauranga Māori connections

Digital Activity (15 mins)

NZ Biodiversity Challenge Game

Students use the interactive "Biodiversity Tagger" game to identify native vs introduced species in different NZ habitats. The game shows photos and students must quickly categorize each species.

Extension: Advanced students can create their own habitat biodiversity comparison using data from different regions.

Launch Game

Main Activity 2 (15 mins)

Species Gallery Walk & Māori Connections

Each pair presents their endemic species research to the class in a gallery walk format. Focus on sharing:

  • What makes their species unique
  • Traditional Māori knowledge about the species
  • Current conservation status
  • Biggest threats facing the species

Cultural Connection: Discuss how whakapapa (genealogical connections) applies to endemic species - they are truly "children of the land."

Plenary (10 mins)

Biodiversity Threat Analysis

As a class, create a mind map of threats to NZ biodiversity on the whiteboard:

  • Introduced species: possums, stoats, rats, cats
  • Habitat loss: farming, urban development
  • Climate change: changing temperatures and weather patterns
  • Human activities: pollution, tourism pressure

Reflection Question: Which threat do you think is the biggest, and why?

Cultural Connection: Māori View of Biodiversity

In te ao Māori, all living things have mauri (life force) and are connected through whakapapa. Endemic species are considered taonga (treasures) that have been gifted to Aotearoa. The concept of kaitiakitanga means we are guardians responsible for protecting these unique species.

Traditional Knowledge Example: Māori knew that when the kowhai flowers bloomed, it was time for certain fish to spawn, showing deep understanding of ecological connections.

Take-Home Experiment

Backyard Biodiversity Survey

Equipment: Phone camera, notebook, magnifying glass (if available)

Method:

  1. Choose a 2m x 2m area in your garden or local park
  2. Spend 15 minutes identifying all living things you can find
  3. Take photos and note which are native vs introduced
  4. Record your findings using the provided data sheet
  5. Upload findings to iNaturalist NZ (optional)

Extension: Compare your findings with a classmate's from a different area.

Assessment Task

Endemic Species Conservation Report

Task: Write a 300-word report on one endangered endemic NZ species, including:

Due: Next lesson | Assessment Level: Achieved/Merit/Excellence

📋 Teacher Planning Snapshot

Ngā Whāinga Ako — Learning Intentions

Students will engage with this resource to build understanding of Aotearoa New Zealand's ecosystems, biodiversity, and the role of kaitiakitanga in environmental stewardship.

Ngā Paearu Angitū — Success Criteria

  • ✅ Students can explain key concepts from this resource using their own words.
  • ✅ Students can connect the content to real-world environmental contexts in Aotearoa.

Differentiation & Inclusion

Scaffold support: Provide sentence starters, word banks, or graphic organisers to scaffold access for students who need it. Offer entry-level and extension tasks to address a range of readiness levels.

ELL / ESOL: Pre-teach key vocabulary and provide bilingual glossaries where available. Allow students to respond in their home language first.

Inclusion: Use accessible formats. Neurodiverse learners benefit from chunked instructions and choice in how they demonstrate understanding.

Prior knowledge: Best used after the relevant lesson sequence. No specialist prior knowledge required for entry-level engagement.
