Publisher's Summary

Rock collecting has never been quite like this! When the class forgets to do its homework, a field trip through the Earth's crust, into the center of the Earth, and out through a volcano will teach them not to forget their assignments again - and then some!
Take another ride on the Magic School Bus.

I liked it

I chose this rating because I liked the story. I would recommend this to anyone who likes rocks, short audio books and magic 🚌.
