For K-12 science teachers, National Geographic, in collaboration with wildlife filmmakers Jim and Jamie Dutcher, offers this downloadable guide to teaching about the Gray Wolf in North America. This guide is designed to be used by science instructors in traditional classroom settings as well as those who teach in out-of-school learning environments, such as after school programs, museums, zoos, and libraries. Within this guide, instructors will find a number of interactive learning activities organized by grade levels( K-3; 3-5; 6-8; and 9-12). These activities cover topics including human perceptions of gray wolves, the role of the wolf pack and social organization to the wolf species, and information about the change in gray wolf population in the United States over time. The guide is presented as a downloadable PDF; related materials, including a video highlighting the Dutcher's work, are available on this site.
