Lesson 1: Water Resources and Water Footprints (High School)
Used this activity? Share your experiences and modifications
This lesson helps students understand why Earth is considered the "water planet." Students analyze how much of Earth's water is available for humans to use for life-sustaining purposes, and they explore the concept of water scarcity in both physical and economic terms. They look at the many ways that humans use water and investigate international trends in agricultural, industrial, and household water consumption. The lesson also sets up the focus of this course: the concept of water footprints. Students explore how water footprints are an invaluable tool for identifying patterns of water use so that individuals, businesses, and even nations can more effectively manage their use of one of the most precious resources on Earth: water. Critical to this exploration is a visit to Watercalculator.org
, where students calculate their personal water usage, analyze the results, and set a base point for tracking and conserving their water use.
This is the first 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.
Skills and concepts that students must have mastered
Students must have mastered the scientific method and basic science principles; the water cycle; 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.
