Turtle Lifecycles: Great Barrier Reef Science for Primary Students

 

Turtle Life Cycle

 

The turtle lifecycle is one of nature’s most fascinating journeys – and a perfect topic for Australian teachers exploring science, sustainability, ocean heritage, and ocean ecosystems through the Australian Curriculum. By focusing on turtles of the Great Barrier Reef and South East Queensland, students can connect learning with real-world local habitats and understand how humans can help protect these graceful ocean travellers.

 Turtles of the Great Barrier Reef and South East Queensland

Green turtle

Six of the world’s seven marine turtle species visit Queensland waters, including the Green Turtle, Loggerhead Turtle, Hawksbill Turtle, Olive Ridley, Flatback, and the occasional Leatherback Turtle.

  • Green and Loggerhead Turtles are most commonly seen around the Sunshine Coast and Great Barrier Reef.
  • Flatback Turtles are unique to Australia and often nest on Queensland beaches.

These species play an important role in keeping seagrass meadows (found near Moreton Island) and coral reefs healthy.

The Turtle Lifecycle Turtle hatchling

Teaching the turtle lifecycle provides a hands-on way for students to explore growth, change, and survival. The main stages include:

  1. Eggs – Female turtles come ashore at night to lay eggs in the warm sand.
  2. Hatchlings – Tiny turtles break free after about 6–8 weeks and make a perilous dash to the sea.
  3. Juveniles – They drift on ocean currents and feed in floating seaweed beds.
  4. Adults – After decades at sea, turtles return to their birthplace to nest, completing the life cycle.

This sequence supports Science Understanding: Biological Sciences (Years F–6), where students explore living things’ life stages and life cycles.

Local Context: Habitat, Season and Threats

In South East Queensland, turtle nesting season runs from October to March. Students can investigate local beaches such Turtle laying eggs as Noosa, Coolum, and Mon Repos, where Loggerhead and Green Turtles lay eggs.

Common threats include:

  • Plastic pollution and marine debris mistaken for food
  • Coastal development reducing nesting habitat
  • Climate change, which affects sand temperatures and hatchling gender
  • Boat strikes and fishing nets

These topics link directly to the Sustainability cross-curriculum priority, encouraging students to consider how their actions affect marine ecosystems.

Aboriginal turtle art

For thousands of years, Aboriginal and Torres Strait Islander Peoples have had deep cultural and spiritual connections to

sea turtles. The Kabi Kabi, Butchulla, and Woppaburra Peoples along the Queensland coast recognise turtles as part of their ocean heritage, using traditional knowledge to manage marine environments sustainably.

Including these perspectives helps students appreciate First Nations knowledge systems, aligning with the Aboriginal and Torres Strait Islander Histories and Cultures cross-curriculum priority.

 

Classroom Activities and Teacher Handouts Plastic Diary

  1. Lifecycle Activity Diagram – Students order and label the turtle life stages using photos from local species.
  2. Plastic Diary – Get students to create a plastic diary and discuss solutions to reduce waste.

Nurturing Ocean Stewards: Teaching Children About Human Impact on the Ocean

 

As educators, we hold a substantial responsibility to shape young minds and cultivate a sense of stewardship towards our planet. One of the most critical lessons we can impart is the understanding of human impact on the ocean. The ocean, covering more than 70% of our planet, is vital to our survival and well-being. By teaching children about the ways in which human activities affect the ocean, we empower them to become informed and responsible global citizens who actively contribute to ocean conservation efforts.

We love educating children (and adults) about the ocean and feel a duty to ensure that an environmental message is at the core of what we do. Click the link to watch our Human Impact video for schools and read on for useful ideas and resources to assist you as educators to plan your teaching about Human Impact on the Ocean….

Human Impact Curriculum Themed Incursions for Primary & High Schools
