On the Ocean Floor Exuding her usual air of competence, Ms. Frizzle drives the magic school bus to the beach, over the sand, and into the waves to take her wisecracking class on a tour of an intertidal zone, the continental shelf, the deep sea bottom, and a coral reef. Lost in the Solar System The field trip to the planetarium is foiled when the museum turns out to be closed, but Ms. Frizzle saves the day. The Magic School Bus turns into a spaceship and takes the class on a trip zooming through the atmosphere, to the Moon, and beyond! With up-to-date facts about the solar system, revised for this edition.
