The Magic School Bus

The Magic School Bus Inside the Earth by Joanna Cole, 1987.

Ms. Frizzle’s class has a new student, Phoebe, who is about to discover that Ms. Frizzle is no ordinary teacher and that her class trips are nothing like any other field trip.  Ms. Frizzle’s class is studying the earth and rocks, and she assigns the students homework to find a rock and bring it to class.

However, even though it sounds like an easy assignment, only one person actually brought a real rock to class.  The others either didn’t bring anything or brought in pieces of old Styrofoam, bits of broken glass, or chips of concrete from the sidewalk.  With only one real rock for the class’s rock collection, Ms. Frizzle decides that the class should to on a trip to collect more.

She takes the class on a field trip to a real field, but they’re not just going to collect rocks that they find lying on the ground.  The bus changes itself into a steam shovel, and Ms. Frizzle passes out shovels and jackhammers to the students.  They start digging down into the earth, uncovering new layers of rock as Ms. Frizzle explains what types of rocks are in the layers and how they formed.

Before the field trip is over, the school bus, along with all the students, falls through the ground and into a massive cave.  They continue traveling all the way down through the center of the earth and out the other side, ending up on a volcano, where Ms. Frizzle calmly explains about volcanic rocks.

I like the picture at the end of the book, after the kids return to school, which points out that there are things all around them that are made out of the different kinds of rocks and minerals that they learned about on their trip.  Each type of rock is also shown in the class’s rock collection along with notes about the type of each rock and how it can be used.

The book ends with a mock phone conversation between a reader and the author and artist about the impossible things that happen in the book but noting the factual information contained in the story.  The book was featured on Reading Rainbow.  It is currently available online through Internet Archive.
