Youth who participate in the National Science Experiment will examine the properties of water-absorbing polymers, which are long chains of molecules that can be used in environmental applications such as agriculture, erosion control, soil management, and environmental clean-ups. Youth of all ages will test the effectiveness of polymers in an easy-to-administer soil and water experiment and then post their findings online to engage in dialogue with fellow youth nationwide. http://www.4-H.org
