Welcome to EnviroDIY, a community for do-it-yourself environmental science and monitoring. EnviroDIY is part of WikiWatershed, an initiative of Stroud Water Research Center designed to help people advance knowledge and stewardship of fresh water. "This is experiential learning at its best: getting kids in the stream, getting them interacting in their environment." Students at Milton Hershey School in Pennsylvania are deploying water-quality-monitoring sensor stations in a creek that runs through their campus.
