This series is not for the faint of heart. Brave readers will squirm through pages about nasty bugs, disgusting foods, and foul animals. Gross Stuff at Home highlights the many ways bacteria can spread throughout a house, though it stops short of discussing the health risks these germs pose. Gross Stuff in History will leave readers grateful to live in a time with modern sanitation. While the content may make some children overly cautious about invisible germs, it will certainly delight fans of all things gross. Large, stomach-turning photos accompany every page, amplifying the ick factor. Vocabulary words are bolded to support comprehension, and back matter includes additional facts and a glossary. The books are leveled, with longer sentences and more advanced vocabulary to challenge developing readers. Despite the stomach-churning subject matter, this series provides valuable reading practice and is sure to entertain kids who enjoy learning about the slimy, smelly, and downright disgusting. VERDICT Recommended for school and public library collections where high-interest, gross-out nonfiction circulates well.
