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: My name is Ralphie. I am one of the kids in Ms. Frizzle's class. Maybe you've heard of Ms. Frizzle. She takes us on lots of field trips in the Magic School Bus. We never know what's going to happen when we get on that bus, but we do know that we'll learn about Ms. Frizzle's favorite subject-science! Once Ms. Frizzle took us all over the U.S. looking for bats. We thought she was batty! But then we found out some really amazing things about bats, like what they eat, where they live, how echolocation works, and lots more bat facts and bat myths. In this book, I tell you everything that happened on that trip, the time we learned The Truth about Bats. . . . Book Dimension : length: (cm)19.3 　　　 　　　　　 　　　　　 width:(cm)13.5
