During the course of the program, classrooms can participate in several unit-long activities which focus on weather, geology, and mapping. Live e-mail exchange between students and scientists, authors, and explorers enhance the research done in the classroom. A print teachers' guide which is sent in advance of the unit contains activities and recommended Web resources.
Teachers also receive weekly activity units via email and daily update information.
Students are encouraged to email questions to special guests, respond to a question of the week, and communicate with each other. They can publish their work and ideas on the site.
