The Magic School Bus is a series of children's books about science, written by Joanna Cole and illustrated by Bruce Degen. Designed for ages 6-9, they feature the antics of Ms. Valerie Felicity Frizzle and her class, who board a sentient anthropomorphic Type A school bus which takes them on field trips to impossible locations, including 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 has a pet lizard named Liz, who accompanies the class on their field trips.
