Ms. Hansen and the Explorers are very interested in learning--they want to know everything they can about the human body. But they aren't alone! The Zelmans, Xeni and Zeno, have come from their planet to learn about Earth's beings too! They travel past the eyelids, through the eyes, into the optic nerve to learn how the eyes provide the sense of sight. Come along as the Explorers and their favorite guests tour the eyes.
