(3) 4-6 Illustrated by Boris Zaytsev. Photographs by Cheryl Powers. Blood, snot, warts, scars, vomit--who wouldn't want their experiments to yield these gross-out results? Thomas provides simple step-by-step directions for mixing easily found ingredients to create faux versions of the above. Most of the projects are accompanied by a photo and a few caricatures. Tips on using the results and warnings about allergies and the occasional need for adult help are included.

(4) K-3 Illustrated by Dianne Eastman. Ideal for browsing, this volume is loaded with a variety of diversions, including riddles ("How can you identify a dogwood tree?" "By its bark"), trivia, knock-knocks, logic problems, and optical illusions. The layout is visually appealing, although some of the dark illustrations resemble poorly reproduced photocopier art.
