For flood or storm emergency assistance, contact the VIC SES on 132 500 and for life threatening emergencies call 000. 

You can access current emergency information by calling the VicEmergency Hotline on 1800 226 226 or sign up to receive regular updates regarding flooding via the emergency.vic.gov.au website and app.

Waterbug and platypus adaptations (Years 5-6)

Wetlands waterbugs colouring sheet
Wetlands waterbugs colouring sheet: search for 'colouring sheets' to download it.

In this lesson sequence, students explore the diversity of waterbugs in their local waterway and some of the adaptations that enable them to survive and (hopefully) thrive in their habitat. It also showcases the adaptations that make the platypus such a special resident of our waterways.

Waterbugs (aquatic macroinvertebrates) are an important but mostly invisible element of our local waterways. They are a crucial food source for other animals and the biodiversity of waterbugs is used as an indicator of waterway health.

Activities

Waterbugs from Kororoit Creek

Activity 1: Identifying waterbugs

Students identify the waterbugs in a sample and draw conclusions about the health of the waterway based on the sensitivities of the waterbugs found. This activity is most effective when conducted as part of a field excursion. If this is not possible it can be run as an in-class activity.

Activity 2: Waterbug adaptations

Students explore the different ways in which waterbugs obtain oxygen.

Activity 3: Platypus adaptations

Students use technology or craft materials to explore platypus anatomy and how they are adapted to their habitat.

Activity 4: Where are the waterbugs?

Students explore a scenario about a river then play a game to discover why the waterbugs are disappearing.

We monitor rivers and creeks so we know if their condition changes or our improvement programs need adjusting. Learn how we assess river health and view current data.
