Short paragraphs and full-page ­photos take readers through the history of each object, how they're made today, and how the item is important to us. While titles are meant for a younger audience, the text does not shy away from the reality of some of the topics, such as the use of unprotected child workers in the production of chocolate. ­Vocabulary words are bolded in contrasting colors throughout. Along with a glossary and index, back matter includes a suggested activity, and resources for further reading. Whether readers are looking for fun facts or deeper discussions, this series shows how everyday objects can play an important role in our lives. VERDICT Good for inquisitive ­elementary readers.
