The Bush Science Center provides classrooms and laboratories for both the physical and behavioral sciences, as well as for mathematics and computer science. The building contains 38 teaching and research laboratories, with physics on the first floor, biology and a computing lab on the second floor, and chemistry and mathematics on the third floor. An observatory with small, high-powered telescopes, for use by the astronomy classes, is on the fourth floor.
A separate two-story wing, the Johnson Center, houses the psychology department. The Johnson Center contains a sleep laboratory and a small animal learning laboratory. The two facilities are used primarily for senior research projects. The animal lab is used strictly for response and conditioning exercises.
Completed in 1969 at a cost of $3.5 million secured by a gift from the Edyth Bush Charitable Foundation, the building is trimmed in travertine marble from Pietrasanta, Italy, which is considered one of the world’s most beautiful building stones.
