Teaching Marine Biodiversity in Australian Secondary Schools

Marine Biodiversity

Australia’s oceans are home to some of the most diverse marine ecosystems on Earth – from the vibrant Great Barrier Reef to the deep trenches of the Southern Ocean. Teaching marine biodiversity in secondary schools is not only relevant and engaging, but essential for developing scientific literacy and environmental responsibility in young people.

In this blog, we’ll explore why marine biodiversity matters, how it sustains healthy ecosystems, and how you can integrate this topic into your secondary science or sustainability curriculum.

🌊 What Is Marine Biodiversity? Ocean Biodiversity

Marine biodiversity refers to the incredible variety of life in the ocean – from microscopic phytoplankton to apex predators like sharks and orcas. This diversity plays a critical role in maintaining ecological balance, supporting food webs, and enabling natural resilience to environmental change.

Secondary students can investigate biodiversity through the lens of biology, environmental science, and even global systems. Exploring the interconnectedness of ocean life encourages deeper thinking about sustainability, conservation, and human impact.

🧠 Why Marine Biodiversity Matters

Marine biodiversity supports life on Earth in complex and far-reaching ways:

  • Ecosystem stability: Different species maintain ecosystem health through their unique roles

  • Oxygen production: Oceanic phytoplankton produce more than 50% of Earth’s oxygen

  • Food security: Healthy biodiversity supports sustainable fisheries

  • Scientific breakthroughs: Many marine species hold keys to future medical and technological innovations

  • Coastal protection: Reefs and mangroves buffer communities from erosion and extreme weather

Understanding these systems prepares students to engage critically with current environmental challenges, including climate change and biodiversity loss.

 

Marine Biodiversity in the Secondary Classroom

Here are five ways to explore marine biodiversity with high school students, linked to the Australian Curriculum Version 9 in Science, Geography, and Sustainability:

1. Investigate Australian Marine Ecosystems

Use real-world examples like the Great Barrier Reef, mangrove estuaries, or seagrass meadows. Encourage students to examine species interactions, ecological roles, and environmental threats. Book an Ocean Life Education incursion or excursion to engage students with live marine animals and expert educators.

2. Classification & Adaptations Humpback taxonomic chain

Use biological classification frameworks to group marine species (e.g., phyla, classes, orders). Focus on structural adaptations that enable survival in different habitats – from bioluminescence in deep-sea creatures to the streamlined bodies of pelagic fish.

3. Build a Marine Food Web

Challenge students to construct complex food web models showing predator-prey relationships and trophic levels. Discuss what happens when a keystone species is removed. This is an effective way to introduce systems thinking.

4. Analyse Human Impacts

Explore issues such as coral bleaching, plastic pollution, ocean acidification, and overfishing. Use case studies, scientific reports, or host an Ocean Life Education Human Impact Incursion to examine real-world data and encourage critical discussion.

5. Explore Indigenous Perspectives

Incorporate Aboriginal and Torres Strait Islander ecological knowledge of marine environments. Traditional practices around sustainable fishing and ocean stewardship align powerfully with modern conservation efforts and are embedded in cross-curriculum priorities.

Curriculum Connections Great Barrier Reef Habitat

Marine biodiversity aligns with key strands in the Australian Science Curriculum Version 9, including:

  • Biological sciences (ecosystems, classification, adaptations)

  • Science as a human endeavour (sustainability, ethical use of resources)

  • Cross-curriculum priorities: Sustainability and Aboriginal and Torres Strait Islander Histories and Cultures

It also supports learning in Geography, Health, and STEM education more broadly.

Inspire the Next Generation of Ocean Stewards

Teaching marine biodiversity at the secondary level equips students with the knowledge and critical thinking skills needed to understand and respond to global environmental issues.

It also fosters a sense of personal responsibility and connection to our oceans – empowering the next generation to act as ocean stewards and advocates for sustainability.

Sharks are apex predators. As top-level predators, they help maintain the balance of marine life, supporting the health of coral reefs, seagrass beds, and other critical habitats. Without sharks, our ocean ecosystems can become unstable, leading to the overpopulation of some species and the collapse of others.

Link: Ocean Life Education Video – Why We Need Sharks

🦈 Sharks are Guardians of the Ocean

Movies and myths often cast sharks as villains, but they’re essential guardians of the ocean. Teaching kids about sharks helps bust common myths and builds respect for these incredible animals. It also opens up conversations around the marine food chain, shark conservation, and the importance of protecting ocean biodiversity.

Shark Resources from Ocean Life Education

🔍 What Role Do Sharks Play in the Ecosystem? Why we Depend on the Ocean

  1. Balance Marine Populations
    Sharks regulate the populations of prey species like rays and smaller fish, preventing them from overgrazing critical habitats like seagrass and coral reefs.
  2. Support Ocean Biodiversity
    By preying on weak or sick individuals, sharks help keep marine species healthy, promoting genetic strength and ecological balance.
  3. Drive Evolution
    Sharks influence the behaviour and evolution of other marine animals. Their presence encourages adaptive traits and survival strategies in prey species. Watch our Shark Adaptation Mini Video here and check out our Adaptation themed programs.
  4. Indicate Ocean Health
    A thriving shark population is a key sign of a healthy ocean. Sharp declines in shark numbers often signal wider problems in the marine food web, with long-term consequences for both wildlife and human communities.

 

📚 Cross-Curricular Classroom Connections

Teaching about sharks links to several key areas of the version 9 Australian Curriculum:

Science (Biological Sciences): Study food chains, life cycles, animal adaptations, and ocean habitats. See our Primary Incursions with these themes.

Geography: Explore the distribution of shark species and the environmental conditions they need.

English: Inspire persuasive writing, shark fact files, and conservation-themed research projects. See our Ocean Literacy Incursions.

Teaching Humpback Whale Classification: Resources for Primary Schools

Humpback Classification

 

Every year, mainly between May and October, humpback whales migrate along Australia’s East Coast, providing a real-world example for studying classification in the science classroom. These iconic gentle giants really capture students’ imagination and offer the perfect living opportunity to teach key biological concepts like grouping living things, external features, adaptation, and habitats. In this blog, we look at how to use humpback whales to support curriculum-aligned learning for primary students, with a focus on humpback whale classification, adaptations, and marine ecosystems and habitats.

Check out our educational programs that support this curriculum learning.

Link to classification resources here.

🐋 Why Teaching Classification Through Humpback Whales Engages Students

Whales are classified in the order of cetaceans (the same as dolphins and porpoises). Cetaceans are mammals that are adapted to life in the ocean.

Classification helps students understand how scientists can group living things based on their shared or common features. Using an iconic Australian cetacean species like humpback whales connects learning to real life and encourages environmental awareness.

 

A Real-Life Example on our Doorstep

The East Coast of Australia, especially between Hervey Bay, Sydney, and Byron Bay, is one of the best places in the world to observe humpback whales from the shore. Their visible behaviours and impressive size make them an exciting and accessible teaching focus. Students can even do an excursion to the shore to watch the spectacle for themselves as well as learning about humpback whale classification in the classroom.

Find out where to spot humpback whales off East Coast Australia

 

🧠 Key Humpback Whale Classification Concepts to Explore

Humpback taxonomic chain

Kingdom – Animalia

Phylum – Chordata (they have a backbone)

Class – Mammalia (they breathe air, are warm-blooded, and nurse young)

Order – Cetacea (includes whales, dolphins, and porpoises)

Species – Megaptera novaeangliae (humpback whale)

 

Discuss How Whales Differ from Fish:

Classified as mammals not fish…

🐳 Use lungs and blow-holes to breath, not gills

🐳 Warm blooded

🐳 Give birth to live young

Swimming technique…

Whales use their horizontal tail (called a fluke) to swim up and down, while fish use their vertical tail to swim side to side.
