By the end of this activity, students should be able to:

  • recognise that invertebrates are part of freshwater ecosystems
  • safely capture freshwater macroinvertebrates for observation
  • group macroinvertebrates according to observable features.

Nature of science

Observation is a key component of science. Observation can happen at many levels – from carefully looking at creatures while working at the water’s edge, through to full identification and classification.

Useful links

Macroinvertebrate monitoring is an important part of measuring stream health. There are numerous freshwater monitoring guides available. Check with your local regional council for resources and kits specific to your area.
