The Skeleton Scare takes readers through the Hugh Mann Costume Company, where they’ll learn about a different bone in each room. As Ms. Frizzle and her class work their way through the factory, they keep seeing a strange skeleton. Yikes! Is it following them? Maybe, but it doesn’t stop the kids from learning all about skeletons: why we need them, what different bones are for, what makes bones grow, how bones get fixed after they’ve been broken, and lots of other facts about our skeletons.
