All ages (years 3-12)

Discovery Centre guided tour

Where does our drinking water come from? What goes on beneath our city? How is water recycled? Take a guided tour of the water cycle story from the catchments to the coast and learn how we're helping to create a sustainable future.

Years 3-6

Stormwater story

How does litter and rubbish end up in our rivers and creeks? Students act out a journey down the Yarra River from catchment to coast to see how humans impact stormwater quality.

Wetland food chain game

What happens to our food chain when there are too many predators? Students find out through this interactive game, which illustrates the food cycle and energy transfer in our special wetland environments. The game demonstrates the effects of pollution and predators on the transfer of energy between trophic levels.

Years 3-7

What goes where?

Where should household wastes go? What can go onto the compost heap, the recycling bin or the trash? What should go into the sewerage and stormwater systems? In this interactive game, student teams actively debate the answer to these questions.

Years 3-10

Water smart city

Explore stormwater and pollution in the Lego city! Students are introduced to the impacts of stormwater on our waterways and bays. Working with the model, students address stormwater issues and adapt the city to make it water smart.

Years 5-10

Living in a catchment

What is a catchment? What's in a catchment? What are the differences between the upper, middle and lower regions of a catchment? Students work in teams to construct a giant jigsaw puzzle to study the factors that affect water quality.

Water recycling model

This model helps students better understand where our water comes from and the ways that recycled water can be used in horticulture, agriculture, industry and recreation. Real water flows over the model's catchment landscape with sound effects and track lighting showing different features of the model in action.

Years 7-9

Micro-organisms at work

Discover the micro-organisms that play an important role in the biological treatment of wastewater at the Western Treatment Plant. Learn about how different environments in the treatment process are managed to encourage different micro-organisms to go to work.

Our Melbourne's Water Story website hosts a variety of Teacher Resources that you can complete with students before and after visiting the plant. These include hands-on investigations and discussions, enhancing your students' tour experiences and supporting units of work around wastewater treatment.
