This read-aloud alphabet book has over 200 scientific vocabulary terms whose explanations are written and illustrated in a friendly style. Each alphabet letter page has critical thinking questions for fun discussion between child and parent and additional more in-depth information for the parent. Learning opportunities about science and the natural world include the small (algae, barnacles, and reindeer poop), the large (reindeer, walruses, dolphins, and whales), and the amorphous (greenhouse gases). Photos by the author and her husband illustrate camouflage, permafrost, an up-close and personal walrus, and the oddly shaped eggs of the kittiwake. A final essay about climate change in the Arctic includes extraordinary resources for kids, tweens, and teens with coloring pages, puzzles, games, videos, science activities, quizzes, and extra reading for teens and adults.
