In The Field Guide to Polar Animals, young readers discover the 1920s journal of a fictional zoologist who traveled to the subarctic region and Antarctica. Designed as an antique journal with an embossed cover, the book is filled with observations about the animals he encounters on his journey to the ends of the earth. From polar bears to penguins, children learn all about wildlife in the planet's most extreme environments. Detailed illustrations, maps, photographs, and handwritten diary excerpts make readers feel as if they're part of the expedition, while the build-it-yourself components engage and entertain them.
