Gr 3-6--Covering a broad spectrum of topics, these bright and well-designed volumes are impressive both in terms of content and presentation. All the titles are logically organized, and the writing style is relaxed and lively. Clear color photographs and well-labeled diagrams appear on every page and complement the texts nicely. Colorful boxes offering additional interesting facts ("Ancient scholars, called alchemists, believed they could change metals into gold or produce other amazing results.") appear throughout the texts, and important words are highlighted in bold font and defined in the glossaries. All the books conclude with a "Show What You Know" quiz, which asks questions such as, "What characteristics are common for organisms in the Kingdom Plantae?" These titles will be useful for report writers and classroom instruction, but should attract their share of browsers as well.[Page 31]. (c) Copyright 2012.
