(3) 4-6 Useless Knowledge series. Organized into topic areas (e.g., “Human Body,” “Chemistry”), this collection contains fascinating and occasionally gross trivia about ourselves, our planet, and our universe. Readers learn, for example, that jellyfish can live forever; that you’re awake during brain surgery; and that astronauts left poop on the moon. Humorous cartoon illustrations, such as a drawing of lighter-than-water Saturn enjoying a bubble bath, accompany each fact.
