Magic School Bus Science Chapter Book #20.

Ms. Frizzle's class blasts off for another adventure to learn about rocks and minerals and to end up in the Wild West. When Carlos brings a mystery rock to school, he hopes Ms. Frizzle will tell him what kind of rock it is. But the Friz doesn't like to tell when she can show. That's how the class ends up on a wild rock hunt in the Wild West, trying to solve a mineral mystery! They take a stagecoach ride, pan for precious gems, and even explore an old mine. Sure, the going gets a little rough at times, but this road trip rocks!

The kids in Ms. Frizzle's class are getting ready for the Wild Weather Show. To prepare, they take a field trip to the Weatherama Amusement Park. The class finds out just how wild weather can be when they accidentally fly right into a powerful tornado.

On a special field trip in the magic school bus, Ms Frizzle's class learns at first hand about different kinds of rocks and the formation of the earth.
