To celebrate its 20th anniversary, Scholastic is re-releasing the ten original Magic School Bus titles in paperback. With updated scientific information, the bestselling science series ever is back!

The classroom is decorated as Dinosaur Land, but Ms. Frizzle-inspired by an archeological dig-craves a more authentic experience. The Magic School Bus turns into a time machine and transports the class back millions of years to an adventure where they learn about dinosaurs, their habitats and diets, and even a Maiasaura nesting ground.
