Project Description


Water programs focus on water conservation, quality, monitoring and aquatic ecosystems.

Duration of activities: ~ 50 minutes
Available for: Year 7 to 10


You can mix and match activities from two different programs.
* Starred activities should be booked concurrently as the content is closely linked

  • Walk along the Merri Creek and see how it has changed over time with different uses
  • Use survey techniques to assess the current health and problems for the Merri Creek
  • Learn about the “Index of River Conditions”, a national system of determining the health of any given waterway
  • Identify current impacts affecting the health of the creek ecosystem and discover possible solutions such as litter and weed management techniques
  • Get into the science of the health of our waterways
  • Use chemical and physical tests to monitor water quality (depth, temperature, speed of flow, turbidity, pH and salinity)
  • Assess creek & habitat health using the data gathered
  • Discuss the reasons why different results were found and what the results relate to in terms of the health of the creek
  • Evaluate how healthy the creek is for plants, animals and humans
  • Net for fresh-water macro-invertebrate animals living in the Merri Creek
  • Learn and participate in a kick sampling technique
  • Identify the aquatic organisms caught and find out how they indicate water health
  • Consider the role of aquatic organisms in maintaining the health of freshwater ecosystems
  • View and identify your catch through the microscopes
  • Calculate the stream pollution and habitat health rating of the Merri Creek based on the pollution sensitivity of the animals found
  • Discuss variables that may affect the health rating of creeks e.g. weather, temperature, sampling techniques etc.
