Field Trip Earth, a project of the North Carolina Zoological Park, is a great place for a "wild" experience, billing itself as "the global resource for teachers, students, and proponents of wildlife conservation." Through the site, you and your students can get involved in field-based wildlife conservation projects ongoing around the world. From the site:
Some of the projects are "live," meaning that research activities, and one or more research scientists, are currently active in the field. These projects are featured prominently on the site. Projects that are not "live" are archived so that students can continue to access the relevant articles, photos, videos, and other materials. All of the projects, though, are similar in that they provide classrooms and others around the world the opportunity to interact meaningfully with wildlife researchers and other conservation experts. Students and other users can read researchers' field diary entries, direct questions to the researchers (and read their responses), listen to recorded satellite telephone calls and other communications, see video taken in the field, and discuss conservation issues with them. In a sense, students can use the interactive resources of Field Trip Earth to become part of the research team itself.
There's much more about the project and activities in a series of articles "About Field Trip Earth" at the site. And then there are the field trips themselves! Examples include: Przewalski Horse Recovery in Mongolia; Carnivores of Sri Lanka; Paradise in Peril: The Chilkoot River region of southeast Alaska … and more.
