When Ms. Frizzle ordered skeleton costumes for us, some of the bones were missing. We headed for the Hugh Mann Costume Compnay to look for them and learned why we need our skeletons, what different bones are far, and what makes them grow. But, why was that strange skeleton following us?
The Magic School Bus takes Ms. Frizzle and her class on a trip around the United States looking for bats. During the trip the class learns many amazing facts about bats, including what they eat, where they live, how echolocation works, and more.
