Through this site from National Geographic, students can learn the latest about the rarest and most endangered species on earth, as well as fragile ecosystems in their own region. “Sights and Sounds” brings students interviews and information about specific regions of the world. At press time, the focus was the Bering Sea. The extraordinarily detailed map allows classes to zoom in and out on certain regions of interest and learn more about the ecosystems in different parts of the world. By defining hundreds of different ecosystems and explaining what differentiates them, the site gives students a real working knowledge of the ecological variation that makes our planet so fascinating. The Wild World maps are designed to help teachers bring into their classrooms the wonders of biodiversity and the urgency of conserving it. The “Educator’s Guide” that accompanies the maps offers lesson plans and activities on subjects like map fundamentals, biodiversity, and ecoregions.
