The Science Lab has exactly only three entrances to it, two from the midship deck (one leads to the Common Room, the other leads to a hallway and the Capitol Preservation Society). There is also a door connecting the science lab to the upper deck. All three entrances are upstairs, with the midship deck doors being in the south-eastern part of the lab, side by side up the stairs. The upper deck entrance is on the north-eastern side, up the stairs, behind three water/grain silos. The main point of interest is the center room downstairs, where a large intersection of pipes take up some of the space in the room, leading down into a large circular platform (which could be a purifier or filter). A large piece of machinery (possibly a purifier) is beside the platform on the right. In the very middle of the room most of the NPCs (such as Doctor Li, Anna Holt, and others) reside. There are three tables holding chemistry sets, vegetables, and other various miscellaneous items. On the left of the tables is a refrigerator, and on the right are two Lockers.
