The Biology Lab is a classroom in the southeast corner of the Basement.  Students and a teacher sit in the front of the room, while lab tables are in the back.  The Biology Lab contains the largest prep room of any laboratory in the school; specimens and chemicals are stored there.  Although it is known as the Bio Lab, it is not the only "biology lab" in the school; anatomy and physiology experiments are usually conducted in Room 412, and marine biology classes are held in Room 205.
