Teaching in the Gelb Science Center began Jan. 6, 2004—a momentous day! The Gelb is Andover's first new academic building in 40 years. Teaching space totaling 48,000 square feet is housed in this three-story building, which allows for better energy savings in this 21st century science center. Additional environmentally sound decisions include the re-use of ledge from the excavation, the harvested woods used for lab desks and chairs, the zinc roof and marmoleum flooring. A Ph neutralization system in the basement neutralizes chemicals before lab waste is disposed.

A smaller lobby area accommodates the request for wider corridors, and the 11-foot ceilings provide a high and open space. The maple furniture and millwork create a feeling of continuity throughout the building. Looking out the windows, one's eyes are drawn across a green lawn to the cemetery, making the view from the third floor, home of the chemistry department, particularly notable.

The science faculty provided significant input for the design of the Gelb Science Center. Their requests for interactive space for faculty and students alike, better maneuverability from classroom to lab stations and a more efficient supply system were met. Lab classroom configurations were designed with flexibility to serve both laboratory and traditional class activities. For example, tall chairs are paired with tabletops that double as both desks and lab stations and can be pulled together for larger groups.

Architects carefully considered the exterior of this addition. The color and texture of the brick and the cream-colored window casings of the Gelb Center mirror neighboring Paul Revere Hall and Commons. In five years, the mortar will fade to match that of Paul Revere Hall.

Clyfe Beckwith, chair of the physics department, worked closely with engineer John Briggs on the design of the new 18 1/2-foot dome in the south-facing observatory. The restored telescope is housed here, and computers capture images to the classroom for study and discussion.
