The Magic School Bus is a series of children's books about science, written by Joanna Cole and illustrated by Bruce Degen. They feature the antics of Ms. Valerie Frizzle and her class, who board an anthropomorphic Type A school bus which takes them on field trips to impossible locations, such as the solar system, clouds, the past, and the human body. The books are written in the first person from the point of view of an unnamed student in "the Friz's" class. The class pet Liz, a lizard, accompanies the class on their field trips.
