Gr 3–5—With rocks and minerals being curriculum topics, libraries are always in need of additional, current resources. These books cover the basic information but they will not engage readers. The reading level is high for the intended age group. The introductions in Crystals, Fossils, and Minerals don’t provide adequate descriptions of the relationships among rocks, minerals, and crystals, and at times the information doesn’t flow smoothly between sections. The chapter spreads are busy with catchy subheadings, short paragraphs under each heading, sidebars, and activities.
