This educational collaboration between Washington University's Tyson Research Center and the Missouri Botanical Garden's Shaw Nature Reserve is designed to engage St. Louis area high school students in scientifically-based exploration of the natural world. Linked programs of field training (SIFT) and field research (TERF) provide teenagers with experiences that realistically reflect research in environmental biology. Participating teens learn a variety of field investigation skills and then have the opportunity to put those new skills to work assisting career scientists with real research projects.
