The Mansfield University Chemistry & Physics Department is housed in Grant Science Center. This newly renovated building features state-of-the-art equipment, laboratories, and classrooms. These modern facilities are used by students and faculty in a variety of experiments and research projects. The Grant Science Center also features a greenhouse and a Spitz planetarium. In addition to the usual laboratory equipment and glassware, the department has a large assortment of instrumentation available for student use.
The previous building was demolished in the late 1940s and replaced by the eastern wing of the present structure. It was originally called Case Hall. In 1967, the building was formally dedicated to Herbert Grant.
Additions to Grant Science Center, including the western wing, were completed in 1970. That project added a 100-seat planetarium, later named for George B. Strait. It also more than doubled the available space for science instruction.
