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.
Classes are timetabled into one workshop from each of the core topic streams, as well as the introductory Mega Water Session.
Explore the workshops offered across the full program at this year's Groundwater Festival below.
An exciting addition for the 2025 program is a fourth core stream that dives into our wildlife's need for water!
FESTIVAL PROGRAMS

Edible Aquifer
Groundwater Geology stream
This activity provides students with a fun and easy way to understand the geology of an aquifer. As they build (and eat!) their very own edible aquifers, students will gain an understanding of confining layers, water tables and aquifer geology.
Curriculum
Year 4: Science WA4SSUE1, HASS WA4HAKUG3
Year 5: HASS WA5HAKUE2
Year 6: Science WA6SSUB1

Groundwater Spider
Groundwater Geology stream
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 students build their own edible aquifers out of ice cream, ice and lemonade, they learn about confining layers, contamination, recharge and water tables.

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

Every Drop Counts
Water Conservation stream
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.
Curriculum

Year 5: HASS – Economics and Business WA5HAKUE2

Flush It!
Water Conservation stream
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.
Curriculum

Golden Pipeline
Water Conservation stream
This fun and interactive session introduces students to the history of why and how water is supplied to the agricultural and goldfields regions of Western Australia. Through role-play, students explore the history of the Golden Pipeline and the legacy left by Western Australia’s most famous Engineer in Chief, C Y O’Connor.

Tapped Out
Water Conservation stream
In this activity students explore what is like to live in a place where water is not readily accessible and promotes discussion about how this may influence life in positive and negative ways.

Water Ways
Water Conservation stream
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.

Danger in Our Town
Water Quality stream
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.

PollutiON, PollutiOFF
Water Quality stream
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
Water Quality stream
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.

Wetland Wonders
Water Quality
What is a wetland? And why are they important? In this engaging and exploratory session, students will learn about wetlands and the role they play in keeping our rivers, lakes and oceans clean by becoming ‘turbidity’ detectives.

Would You Like Salt With That?
Water Quality stream
Students explore the impact of forest clearance on our land, water cycle and water quality. By tasting increasingly salty liquorice, they discover first-hand the effect that increased levels of salinity have on our native vegetation and how it is caused.

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!

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.
