The Earth is covered three-quarters by water, with vast oceans teeming with life from the surface to depths of thousands of meters. Crabs, starfish, octopuses, dolphins, sharks, whales - the forms of life are countless and their variety exceeds all imagination.

You may even encounter an entire class of school children, along with their extraordinary teacher. Ms. Frizzle could not ignore such an exciting area as the world of the deep sea, and the field trip she invites her lucky students on, with the help of the magical school bus that has transformed into a submarine, becomes an exceptional lesson about nature and at the same time an unforgettable adventure.

The Magic School Bus is a well-known series of science books created for children by American author Joanna Cole and illustrated by artist Bruce Degen. In each book, Ms. Frizzle's class, a teacher who loves science and is enthusiastic, experiences a fantastic adventure thanks to a very unusual school bus: it can grow or shrink, travel through space, the depths of the ocean, or even inside the human body, and it can transform in unexpected ways.
