When we turn on the tap or flush the toilet how often do we actually think about the amount of water we are using? This PowerPoint slide presentation and accompanying activity engages students in an investigation of the amount of freshwater they and their peers consume on a daily basis. As they use science and math skills to collect and analyze survey data, learners also brainstorm simple strategies for reducing water waste at home and school. In a world where freshwater supplies are increasingly affected by climate change and pollution, students will understand why we must all conserve this vital resource by reducing our daily "water footprint".
This resource explores human impacts on freshwater resources using an action approach that fosters environmental stewardship. As students collect numerical information about water consumption they build science and math skills in calculating means and percentages, carrying out data analysis and pracitcing critical thinking. Learners also consider the relationship between reduced water use and sustainable living from a local and global perspective.
A class could expand the conservation message of this activity by developing a school "World Water Day" celebration on March 22nd. The event could include water savings posters, displays about human impacts on freshwater and involve a local Indigenous community in presenting traditional practices honouring water.
