K-12 Student Field Trip Guided Tour

For those on a tighter financial or temporal budget, take our public tour (approx. 90 minutes) with a Biosphere 2 Interpretive Specialist to help your students appreciate the history of the Biosphere 2 building itself and learn how it is used today by University of Arizona scientists to study Earth-system science. The tour experience includes an overview of ongoing research projects, as well as interactions with University of Arizona researchers themselves whenever possible. No visit to Biosphere 2 is complete without a visit to the technosphere (specialized basement area) to see some of the machinery that controls the giant laboratory. The technosphere visit ends at the South Lung (variable volume air chamber), with the option of visiting the Ocean Gallery, time permitting.
