The document describes a class trip inside the human eye led by Ms. Frizzle. The class sings a song about eyes and their functions as they travel on the bus. They enter through the cornea and travel to the pupil, learning about the different parts of the eye. The class participates in optical illusions to understand how the brain interprets images from both eyes. Finally, they leave Ms. Frizzle's eye, wondering where their next destination will be.
