Lesson 2: My Water Footprint (High School)
Summary
This lesson centers on a deeper exploration of the water footprint associated with food. Students learned in Lesson 1 that virtual water, especially as it relates to food, typically makes up the majority of their water footprint. In this lesson, they find out why. First, they see an attention-grabbing demonstration of how much water is needed for three food products. Second, they break into groups to do research, and then they teach their classmates about key aspects of water use related to food and agriculture. Next, they think about how their diet is influenced by social groups, advertising, and structures in place at home and at school that encourage them to potentially eat food with large water footprints. Finally, they brainstorm ways they might be able to influence change in those areas. The lesson concludes with students sharing their ideas and providing one another with constructive feedback.
This is the second of the three-part Lessons for Understanding Our Water Footprint: High School Lesson Plans.

This activity is also available in a format appropriate for a middle school level (lower secondary) audience.
Skills and concepts that students must have mastered
Students must have mastered the scientific method and basic science principles; systems thinking; basic numeracy; ability to make concrete abstract thinking as it relates to virtual water and water footprinting; ability to work with a small group or team.
How the activity is situated in the course
This is the first of three lesson plan modules. Each lesson can stand on its own or build on each other sequentially.
Goals
Content/concepts goals for this activity
- Provide examples of how different foods require different amounts of virtual water.
- Learn key topics related to the water footprint of food.
