Interconnecting Growth and Change - COG's Unit - Stage 3

The “Interconnecting Growth and Change” program provides a hands on opportunity for students to discover how living things interact within the mangrove wetland environment.

Students will use a variety of data collection methods to study and observe the health and viability of the mangrove environment. Students will use scientific equipment to test water quality of three different water sources, and look at management strategies that are used within the park protect water quality in the wetlands. The mangrove wetland ecosystem contains organisms that are reliant on each other and the mangroves for food and habitat. Any changes in the ecosystem need to be identified and followed up for management purposes- therefore data collected by the students will be part of the wetland management process. Through this experience, the students will be able to construct a food chain, conduct basic environmental monitoring and identify significant changes that can disrupt this important wetland ecosystem.

Unit outcomes

Students will investigate a local ecosystem to understand the impact of introducing or removing a species (plant or animal) from an ecosystem. Students will develop an understanding of the interaction between living things, and between living things and their environment, and assist in taking actions to conserve both those living things and their environment.

Syllabus Outcomes:

Science and Tech


  • Identifies, describes and evaluates the interactions between living things and their effects on the environment


  • Conducts their own investigations and makes judgments based on the results of observing, questioning, planning, predicting, testing, collecting, recording and analyzing data, and drawing conclusions



  • Demonstrates an understanding of the interconnectedness between Australia and global environments and how individuals and groups can act in an ecologically responsible manner


  • Selects and applies appropriate problem solving strategies.


  • Links mathematical ideas and makes connections with, generalisations about, existing knowledge and understandings of content.


  • Displays and interprets data in graphs with scales of many to one correspondence


  • Uses a variety of mapping skills


Students will be able to:


  • Identify and evaluate interactions between crabs and mangroves
  • Identify other interactions within the Mangrove environment


  • Fills in plotting table and demonstrates basic understanding of data collected, able to draw a conclusion from results with guidance from Education Officer.


  • Display understanding through discussion about the effect groups and individuals can have on the environment. 

Unit Outcomes

  • Discuss how they can help conserve the environment and the living things within it.
  • Record data in an appropriate form and evaluates collected data to ensure that it satisfies the purpose of an investigation.
  • Learn that animals display a range of dynamic relationships within their own populations, with other animals and with the environment.
  • Discuss how this ecosystem will be affected if plants or animals are removed.


Able to demonstrate compass directions, and identify features on a Sydney Olympic Park Map including where they are on the map.
