The latest in the Let’s-Read-And-Find-Out Science series, this Stage 2 title follows a mother bear and her cub as they emerge from their winter den in the Arctic and set out for the ice where the mother can catch a seal meal. Along the way, children learn about Arctic temperatures and conditions and the adaptations that allow polar bears to survive there. After about the first 29 pages, however, the style of the text changes from informative to exhortative. A decrease in Arctic ice is a fact that affects polar bears. This series has already addressed global warming, and its heavy presence in this title seems shoehorned in solely to galvanize readers. Backmatter includes more on global warming and ways readers can lessen their impact on the earth. Chin’s clean watercolor illustrations introduce the presumed narrator, a bespectacled, cartoon polar-bear scientist and realistically portray both the Arctic habitat and the polar bears. In some instances, though, the bears’ facial expressions are anthropomorphized, especially the cub’s and in the latter portions. All in all a rather disappointing effort from a solid series.
