Karla, the coastal tern, explores many questions about the icy worlds of the two polar regions together with beginner readers: Where does the Arctic get its name? Where is the largest ice desert in the world? Which animals and plants live in the polar regions? And why are the poles so important? The short text units in large print provide interesting polar cap knowledge for first-time independent reading. Each chapter is followed by a reading quiz with questions about the text. This way, little world travelers can check if they have understood what they read correctly. At the end of the book, Karla reveals her favorite spot on Earth.
