EARTHLINGS INSIDE AND OUT

Wyatt (The Science Book for Girls, 1997, etc.) adopts an alien’s-eye-view of earthlings, comparing the human body with that of a friendly lifeform from outer space. A cartoon anatomical outline charts the alien Danoid’s first encounter with Pete. Danoid labels hands as primary manipulatives, feet as planet connectors, and knees, multidirectional movement facilitators. Earthling skin, hair, brains, bones, muscles, and organs are measured by these compare-and-contrast standards, delivering information along the way. Sifting through a flurry of text, readers will stumble upon headings marked “Science Fair Ideas,” consisting of simple, at-home experiments such as tracking one’s pulse with a dab of modeling clay or smelling foods that have strong odors. While the concept is attention-getting, and often humorous, the actual information is often overwhelmed by distracting asides, experiments, and reports filed to Danoid’s commander; this compendium may be more worthwhile for browsers than researchers.
