Reef Threats

Ecosystems and Reef Relationships virtual learning experience - program overview and outline

A series of resources that include videos and an activity book that link to threats to the Great Barrier Reef.

In this mini unit, students will observe different animal and plant cells under the microscope. They will investigate the structure and function of different animal cells and observe and describe the function of chloroplast in plant cells. Students will investigate zooxanthellae and their symbiotic relationship with coral and use this understanding to explain coral bleaching. Students will recognise the link between carbon footprint and coral bleaching and identify ways to manage carbon footprints from the individual to community level.

In this mini unit, students will explore the carbon cycle and the four global systems: biosphere, lithosphere, atmosphere and hydrosphere. Students will investigate greenhouses gases and carbon dioxide and describe the relationship between the carbon cycle and climate change. Students will investigate what happens when carbon dioxide is absorbed by seawater and potential impacts of ocean acidification on reef biodiversity. Students will discuss impacts of climate change on ecosystems and everyday changes to reduce these impacts.

A series of resources such as extended investigations, links and GBRMPA links to Marine Science and Aquatics syllabus.

Design the ultimate reef creature

1. Design the ultimate reef creature animal species name.
2. Draw your creature!
a) Would an animal with a shark's body, jellyfish tentacles and stonefish camouflage be the ultimate survivor on a coral reef?
b) Using what you already know, and the information on page 2, create your own Ultimate Reef Creature. Make sure to name your creation and list it’s adaptations in the boxes below, then draw what your creature would look like.
c) Pick your favourite reef creature and tick the adaptations they possess from the list below.
