time travel

Jack and Annie travel in their Magic Tree House back to a Hawaiian island of long ago where they make friends, learn how to surf, and encounter a tsunami.

Ms. Frizzle's class travels on the Magic School Bus to the Mesozoic Era in order to study dinosaurs.

The magic tree house takes Jack and Annie to an African rainforest, where the siblings encounter gorillas and learn to communicate with them.

When Ms. Frizzle takes her class to a dinosaur dig to look for Maiasaura nests, the Magic School Bus turns into a time machine and transports them back into prehistoric times--when dinosaurs roamed the Earth.
