The Arctic Ocean is the smallest ocean in the world. Located on the North Pole, it touches Asia, Europe, and North America. For many months, the sun does not rise over the Arctic, and when summer arrives, the ice barely melts! Young readers will enjoy finding out more about this unfamiliar ocean and its impact on the world. Gr 1–3—Beginning readers will find general information about the five oceans—their locations, seas and currents, resources, and the animals and plants they sustain. Books open with a "Did You Know?" box with geographical or historical information and conclude with a "Fast Facts" page of statistical information. Text runs about two to three sentences per page. Large, high-quality photos of locations, plants, and animals are attractive and usually labeled rather than captioned. Shaded maps of the oceans are a plus, as are the maps that show hemispheres. Some discussed places do not appear on the maps, and Arctic places Hudson and Baffin bays in the Arctic rather than the Atlantic Ocean, an often disputed designation. VERDICT This set does not improve on recently published sets like Heinemann's "Oceans of the World," but remains an adequate supplementary choice.
