Teaching Environmental Science Naturally (T.E.N.), is an interagency, site-based, outdoor environmental science program for teachers. Using the curriculum guides from Project WILD, Aquatic WILD, Project Learning Tree (PLT), and Project Water Education for Teachers (WET), T.E.N.'s activities
focus on local natural resources to provide teachers with hands-on experiences, in their own backyards. Using workshops
lasting from two to five days, T.E.N. trains and enables teachers to provide proven, effective, and fun (!) environmental science education to their students.
Colorado Parks and Wildlife (formerly Division of Wildlife) Pueblo-area field personnel recognized, in 1991, that environmental science can be more effectively taught by integrating science and ecology subjects and teaching them in local, outdoor classroom settings. T.E.N. developed around this idea, and community-based workshops were created to train and encourage educators to use this approach in teaching environmental science.
An important feature of the T.E.N. program is that local teachers are involved in all aspects of the planning and training processes. Each community T.E.N. program is driven by a local Core Team, composed of local educators and natural resource agency personnel. The Core Team members choose the field sites, compile the curriculum, design the workshops, and lead the workshop training programs.
