Espías del Cielo: Sky Spies

This engaging six-part Spanish-language series explains essential scientific concepts in playful, humorous ways. Each book is packed with fascinating facts about science, nature, the human body, and how the study of these concepts has evolved over time (for example, the history of stargazing and locating asteroids in space before telescopes were invented). Questions you never thought to ask yourself, like "why don't cows climb trees?" and "do animals ever cry?", are explained in fun, interactive ways that will support what readers are learning, inside and outside the classroom. The layout of these books includes a balance of photographs, simple diagrams, infographics, and charts that do a great job explaining sometimes difficult-to-grasp concepts. True to Rourke's other series, these books include science experiment ideas that will inspire readers to test out the theories presented in these books. VERDICT A unique and awe-inspiring series that's best suited for larger collections and STEM school libraries. -- School Library Journal
