WELCOME to the Children's Gnangara Groundwater Festival.
Each year, the Festival program is selected from a range of engaging workshops that cover three core topics: groundwater geology, water quality and water conservation. An exciting addition for the 2025 program is a fourth core stream that dives into our wildlife's need for water.
- Groundwater Geology: in these two workshops, students build model aquifers in a cup allowing them to see how these underground formations work - and ultimately enjoy their efforts with an icecream treat.
- Water Conservation: this stream of workshops focus on how water is used and how to do so sustainably in everyday life.
- Water Quality: keeping our water sources free of pollution is critical for a healthy ongoing water supply, so in this stream, workshops explore how our actions affect water quality.
- Water and Wildlife: it's not just us humans who need water to survive; workshops in this stream explore how our native plants and animals need and use water.
Classes are timetabled into four workshop sessions, one from each of the core topic streams, as well as the introductory Mega Water Session.

Bucket Brigade
This popular activity encourages students to think about their water usage as they compete to move the amount of water a person uses in a day from one point to another as a team. This interclass competition is great fun and the pre-and post-discussions help the students understand more about their water use choices.

Danger in Our Town
Have your students got what it takes to become the town's ‘Contamination Busters’? In this problem-solving activity, students build their own model towns and discuss types of land uses that can cause pollution of groundwater before probing their models to determine the source of contamination of the community’s water supply.

Edible Aquifer
Students will explore the concept of water movement through different types of substrates such as sand, clay, rocks and gravel in this tongues-on activity! As they build (and eat!) their very own edible aquifers, students will gain an understanding of confining layers, water tables and aquifer geology.

Every Drop Counts
In this prop-filled activity, students will take part in a game of chance to see how much water they can save or waste in different areas of the house before coming up with their own solutions to saving water at home.

Food Chain Chase
In this active learning experience, students gain an understanding of how water pollution spreads and multiplies through the food chain and its effect on the natural world. Then they will discover some of the ways pollution enters our water sources and think about how we can stop it!

Flush It!
Introducing students to the “Three Ps” in an active race, this activity provides an understanding of what can, and can’t, be flushed down the toilet. Students will classify waste according to the appropriate method of disposal.

Frog-o-logic
Frogs know all about water quality, and your students will too! In this giant board game, our froggy teams will compete to see who knows the most about frogs, conservation and groundwater. The winners go home with a chocolate frog, and everyone goes home understanding how all living things depend on a healthy ecosystem to survive.

Groundwater Spider
This activity provides students with a fun and easy way to understand the geology of an aquifer. As students build their own edible aquifers out of ice cream, ice and lemonade, they learn about confining layers, contamination, recharge and water tables.

PollutiON, PollutiOFF
After constructing their own landscape, students will be able to see first-hand how human actions pollute an environment. They will observe how contamination can spread underground and experiment with ways to clean it up!

River Food Web
Phosphorous is a key nutrient contributing to algal blooms in the Swan River. Students will discover how our daily activities contribute to the amount of phosphorous entering the river then, as they become part of an aquatic food chain, they will see first-hand how algal blooms affect the plants and animals that live there.

Root Pursuit
Can your banksia reach the groundwater before summer? Learning about our local banksia woodlands and how they are dependent on groundwater, they will explore the impact of dropping groundwater levels as they race their roots to water before its too late!

What do you do when you can't turn on a tap?
This simulation activity of daily life in a village introduces students to ideas about what it is like to live in a place where water is not readily accessible. Students will consider how this may influence life in positive and negative ways.

Water Ways
How many places can water travel and be stored during its journey through the water cycle? Students will chart the complex path water takes as they discover that new water cannot be created and how little is fresh water.
