Would you like to be involved in possibly the biggest chemistry experiment ever conducted? The Global Water Experiment is asking students to test the water where they live and share their results with students around the globe. Participants will learn about sustainable water management and the role that chemistry plays in purifying water for human consumption. The results will be featured on an interactive global data map through the end of 2011, the “International Year of Chemistry,” as designated by the United Nations.
Find out how you can participate in the Global Water Experiment (ask your parents for their permission).
