Koons Hall and the adjacent Thomashow Learning Labs form the College’s science hub. They house four prep labs, a wet lab containing live coral and aquaponics, and a dry lab with live animals for teaching animal handling and husbandry. In 2013, a clean lab was introduced for high-end research such as genetics. The Salmon room houses a spectrometer and fluorescent microscopes. A new geology lab was also added in 2013.

Koons Hall was renamed in 1988 in honor of former chairman of the board of trustees and acting president Donaldson Koons.

The attached Edward Beals Greenhouse, added in 2001, shelters temperate succulents, cacti and tropical plants. Two more green houses are used for crop preparation.
