El autobus magico en el cuerpo humano (The Magic School Bus Inside the Human Body)

It all began when Ms. Frizzle showed the class a filmstrip about the human body. They knew trouble was about to start, because they knew Ms. Frizzle was the strangest teacher in school. They started out on a field trip one day at a science museum to see how their bodies get energy. The trip started out like any other trip. When it was time to go, everyone got back on the bus---everyone but Arnold.
