What do animals do in winter? In simple language and color photographs, animal habits are examined. New readers will find the introduction in this series accessible and may use it as a springboard to explore topics in greater depth. Other subjects in the Bullfrog Books series include machines at work, as in the book Diggers (opens in a new window) by Cari Meister.

In this Space Explorers series, topics of interest to younger readers are introduced in clear color photographs and accessible, logically presented text. “Activities and Tools” to extend each subject are included in an index, along with suggestions for finding additional information.

What does jumping on a trampoline have to do with science? Lots, it turns out! The basic physics laws involved are presented in crisp, readable text and action-packed photographs. For readers interested in ecology, Arctic Food Chains (Pogo: Who Eats What?) by Rebecca Pettiford (Jump! 1620314274) is similarly formatted and quite interesting (with just a hint of blood in the photographs). Table of contents, index and additional resources for each title expands the use.
