Aquatic ecosystems

Aquatic ecosystems

Investigate connections within a wetland ecosystem.

Suitable for Geography (General Unit 1, ATAR Unit 3); Biology (ATAR Unit 1, General Unit 4); Integrated Science (ATAR Unit 2, General Units 1)


Our wetlands are under increasing pressure from the demands of population and lifestyle. Students investigate a wetland ecosystem by conducting tests on water quality (salinity, pH, nutrients, turbidity and dissolved oxygen) then sample the macroinvertebrate community and identify the ecological role of each type of organism. Students are encouraged to formulate their own research question, which their data collection will help answer.


  • Discover key components used to measure water quality.
  • Learn about the ecological role of the animals that inhabit a wetland ecosystem.
  • Understand how scientists use data collection to formulate facts.
  • What you can do to help sustain water quality.

Note:  Can also be done as an incursion at a wetland close to your school.
