Barbara Purn is a 2nd grade teacher at Villa Academy, an independent Catholic school in Seattle. This summer, she is traveling to Kenya on a fellowship from the Earthwatch Institute, a nonprofit science-education group, to study the behavior and stress habits of Sykes monkeys. Ultimately, she plans to share her research with her students as part of a unique lesson plan on endangered and threatened species. In this blog, she’s keeping a journal of her educational expedition.
