The American Geosciences Institute (AGI) has produced high-quality educational materials for decades, and its website is a great resource for teachers working in the physical sciences. On the site, visitors can take advantage of collections created to support thematic textbooks or peruse online programs such as EarthInquiry. This particular resource contains a series of web-based and print investigations that allow students "to explore geoscience phenomena using global, national, and local data." The site also contains a physical geology lab manual designed for use in college classrooms and materials for high school students, including an Earth science curriculum complete with classroom activities and quizzes. The site is rounded out by a set of links to content created by other organizations.
