Lesson 3: The Value of a Water Footprint (High School)
Used this activity? Share your experiences and modifications
Session 1 of this lesson begins with a quick activity to get students thinking about their direct and virtual water use. It introduces a few new ideas for virtual water use that may surprise students, including the virtual water required for the products we buy and use. Then students form marketing teams to explore five categories of water use (indoor, outdoor, diet, electricity, and buying habits) and create infographic posters to share what they learn. Then, in Session 2, students remain in five teams to audit the school's indoor and outdoor direct water use as well as several categories of virtual water use: food, energy, and electronics. They use what they learn to create a strategic conservation action plan that incorporates their How to Save Water awareness campaign in an effort to decrease the school's overall virtual water use. The lesson can be conducted as a short project or a more comprehensive capstone project.
This is the third of the three-part Lessons for Understanding Our Water Footprint: High School Lesson Plans.
Appropriate for general high school level (upper secondary) coursework with some background in earth sciences, environmental sciences and social studies.
This activity is also available in a format appropriate for a middle school level (lower secondary) audience.
