The Magic School Bus was a series of children's books intended to teach scientific concepts to children. The books feature the exploits of Ms. Frizzle and her class of students at Walkerville Elementary School who board a magical school bus which takes them on educational adventures to space, under the Earth, into the human body, or to other such locations. The books were written in the first person from the point of view of an unnamed student in the Friz's class. Synopsis: Hi, I'm Phoebe, one of the kids in Ms. Frizzle's class. When we started our unit on butterflies, I figured I would get to see a live butterfly - but I never thought I would get to be one. But when Ms. Frizzle took us on our butterfly field trip, she accidentally turned us all into butterflies! But being a butterfly wasn't all fun and games. We had to battle all kinds of things: wind, birds, even people! We knew we had to win this Butterfly Battle -- before things got carried away!
