Learning Theme: Going Net Zero

Lesson Sequence: Water – In a Decarbonised Economy

From industrial processes and energy production to agriculture and urban planning, how we manage water directly impacts carbon emissions, resource efficiency, and sustainability goals.

Introduction

Water is a critical resource in the transition to a Net Zero economy. From industrial processes and energy production to agriculture and urban planning, how we manage water directly impacts carbon emissions, resource efficiency, and sustainability goals.

In this lesson, students will conduct scientific investigations and experiments to explore how water use, conservation, and treatment can impact a decarbonised economy. They will analyse water as a key factor in sustainability strategies, studying innovative technologies such as water recycling and desalination.

Through hands-on experiments, data analysis, and industry case studies, students will gain practical scientific insights into how businesses and governments are adapting water management to achieve Net Zero.

Introduction

Wastewater management is one of the most energy-intensive systems in our society. Every day, we use vast amounts of energy to treat wastewater—often to a higher standard than the water stored in our dams—only to discharge it into the ocean. In a world striving for Net Zero emissions, this model is no longer sustainable.

In this lesson, students will explore the challenge of reducing the energy footprint of wastewater management in a decarbonised future. Rather than focusing solely on technology, they will approach the issue through a social lens—asking a powerful question: What if we simply used less water?

By applying design thinking, students will identify a water usage habit in their community and develop a strategy to change it. Through collaboration and industry engagement, they’ll uncover how small shifts in behaviour can lead to big impacts in energy savings and sustainability.
