Arnold has swallowed the Magic School Bus! Now, instead of seeing an exhibit of the human body at a museum, the class is taking a look at Arnold's stomach, his intestines, his bloodstream, and more from the inside on this heart-stopping field trip — one the reluctant Arnold would be happy to miss.<br />Series Information: Ms. Frizzle is a teacher like no other; she's bold, offbeat, and kind of wacky. But she loves science and her enthusiasm quickly rubs off on her students. Why learn in a classroom when there's a magical school bus that can whisk everyone off to the center of the action? Whether they're traveling to ocean floors, outer space, or active volcanoes, Ms. Frizzle's class enjoys hands-on learning. And thanks to the way each book is formatted — with speech bubbles, notebook pages, data files, and ink sketches — readers feel like they're part of the adventure too. With an approach to learning that's both exciting and informative, this clever series invites readers to share in the thrill of scientific discovery.
