Lively, curiosity-tickling prose entices children to compare the smallest of the small with something even smaller… and smaller… and smaller… right down to the electron. Engaging and scientifically accurate: “The ones that look like slippers with whiskers are paramecia. The ’whiskers’ on the paramecia are called cilia.” Glossary. Paperback, 32 pages. Ages 6 and up.
