The Science Zone!

This mural is at the entrance to the science hallway with all the other murals, which is why it advertises entrance to 'the science zone.' Additionally, its use of the already present exit sign is funny. The images at the left end of the mural relate to all classes: there are cells and DNA for biology, a sulfur / acid rain cycle for environmental science, physics equations about a monkey on a tree and a spaceship, and drawings of atoms and molecules for chemistry.
