Water is everywhere. But only three percent of water on earth is fresh water. And only a fraction of that is available for people to use. The National Mayor's Challenge for Water Conservation invites teachers and students to learn more about this valuable limited resource and take a series of classroom pledges on behalf of your community to use water wisely.

About My Water Pledge
Classroom Edition

My Water Pledge is a friendly competition between cities across the US to see who can be the most "water-wise" Mayors nationwide will challenge their residents to conserve water, energy and other natural resources on behalf of their city through a series of informative, easy-to-use pledges at mywaterpledge.com.

We've created this companion site for teachers to engage their classes about the many ways water conservation benefits our community. Not only will students learn about the importance of our natural resources and engage in a fun classroom activity, their pledge will go towards their city's standings which will help their city claim the title as the #1 '"water-wise" city in the US.

Win Prizes for Your Class and School

Teachers who complete the pledge with their students at mywaterpledge.com/students will be divided up into five regions: Northwest, Southwest, Midwest, Northeast and Southern and are entered to win a $250 gift card for classroom supplies - and another $250 gift card for their school. There will be one teacher/classroom selected per region for a total of 5 winners.

"As a huge follower of the Wyland Foundation, I challenged my students to take the water pledge with their families for extra credit in my social studies classes. I put the water pledge website on my teacher homework calendar and the results have been amazing!! Poway, Calif., moved into first place for their population group and the kids were thrilled!! Thank you for the wonderful work you continue to do and also enlisting our future ambassadors of our planet, KIDS!!"

Activity Corner

Each year, the National Mayor’s Challenge for Water Conservation introduces new classroom activities about the many ways water shapes our lives. From the water-energy nexus to the story of our nation’s watersheds, we encourage you to share these educational journeys with your students.


What is Eutrophication?

Students will learn what an estuary is, and the upstream process of nutrient loading known as eutrophication. Students will conduct an experiment of their own on nutrient loading and undertake a water runoff audit on campus.

Time needed for activity: approximately 1 hour class prep, with a 30 experiment/data collection (depending on campus and sample size).

Waterway Report Card

Show your students what makes a watershed healthy or unhealthy. Your class will learn what contributes to the health of species living in or around watersheds and what they can do to promote watershed health.

Time needed for activity:
Approximately 2 hours, 30 minutes (1 Hour class prep, background research and video viewing; 1-1/2 hour lab activity)

What Happened Here?

The Story Behind California’s Salton Sea. Between 1905 and 1907 the Salton Sea was accidentally created when the Colorado River broke through diversion canals of a local irrigation systems, flooding, and eventually becoming a 525 square mile lake in the California desert. This activity shows how efforts to manage a watershed can often have many different perspectives.

Time needed for activity:
Approximately 60-90 minutes

Photosynthesize Me - Water, Please

Students will understand the difference between photosynthesis and respiration. Students will learn that when these two processes entail and how plant and animal kingdoms are connected. Students will learn the crucial importance of sunlight, carbon dioxide, and water in both processes.

Time needed for activity: Approximately 30-45 minute class prep and Introduction; 45 minute lab.

"Sponge City" Engineering Design

Students will understand the importance water conservation and of the saying, “Every Drop Counts”, as they build a model city to capture water, not shed water, and will learn the difference between an aqua duct and an aquifer. Students will learn that when a city is built to harness water, store and reuse it, the architecture and design of that city will need to change. Students will learn the importance of designing a waterproof city vs. a “sponge city."

Time needed for activity: Approximately 30-45 minute class prep and Introduction; 45 minute lab.

Irrigation Nation

Students will understand the process of irrigation and the difference between distilled water, tap water and salty water. Students will learn the importance using water that does not contain a lot of dissolved minerals, and how using irrigated water can lead to waters high in dissolved minerals.

Time needed for activity: Approximately 30-45 minute class prep and Introduction; 45 minute lab.
