The 4-H20 project includes introducing curriculum and activities to youth ages 9 – 19 in school enrichment, after school, military settings, and camp settings. One thousand youth will be introduced to and engaged in the project during the the 2012-2013 program year (July 1 - July 30). 

Sacramento County

The Sacramento County 4-H program will continue implementing and expanding its successful 4-H20 Water Wizards Project. In the 12-week 4-H20 Water Wizards project, 4th-6th grade children in after school programs explore water and the environment (the water cycle, watersheds, wetlands, water use and conservation), water properties (taste test, density, salinity, pH, bacteria, turbidity), and create and implement a plan to impact a water issue in their community.  The project includes an afternoon field trip to the American River Water Education Center.  An overnight camp experience allows youth to become scientists and collect data about the water and wildlife at Lake Vera near Nevada City, CA.  Youth served: 500. For more information on the Sacramento County 4-H Water Wizards, please visit: or contact Marianne Bird at
