Comets, asteroids, and meteoroids

Gr 2-4-This series invites young observers to step outside-day or night-and look up. Each volume opens with a basic spread on "Sky Watching," goes on to provide simple answers to similar sets of questions, and closes with similar pages of advice about the best and safest ways to sky watch. Along with duplicate and/or near-duplicate content, factual errors are not uncommon. For example, in Comets, Arizona's Barringer (misspelled "Berringer") Meteor Crater is incorrectly dubbed the "largest known impact crater on Earth," and the Sun isn't really "the source of all Earth's energy" as claimed twice in Sun. Furthermore, a schematic view of the solar system in each volume does a poor job of showing the sun's size in comparison to the individual planets. The photos and digital art, along with the easily digestible text blocks, give these books visual appeal, but the contents are both superficial and untrustworthy. (c) Copyright 2011.
