Gr 5-8-The titles fairly describe the content in these volumes, which will work as standalones. Chapters are brief and focused. The texts, which contain some mistakes, are lean, with sidebars and graphic callouts adding detail, reinforcement, or background information. Notable scientists and their discoveries are included along with a few hands-on suggestions. Occasionally awkward wording will confuse readers, and many captions don't take advantage of their power to instruct. Full-color backgrounds with captioned photos and graphics fill every page, often overpowering the texts. Although they are gorgeous, the photos sometimes function as filler where a diagram would have been more helpful. The accompanying list of URLs is uneven. An attractive but disappointing series.[Page 34]. Copyright 2008 Reed Business Information.
