Teachers' Domain, produced by WGBH and funded in part by the National Science Foundation and the Institute of Museum and Library Services, is "a multimedia digital library for the classroom that provides learning experiences in ways no textbook can." The website offers "classroom-ready resources, as well as media-rich lesson plans and professional development resources" on Life Science, Physical Science, Engineering, and The Civil Rights Movement. The resources are organized by grade level and correlated to national and state standards. To access the Domain, users must complete the free registration form. However, visitors can go through an introductory tour without registering in order to get an idea of what the site offers.
