Gr 3–5—Any young readers wondering how the rare metals in their jewelry, electronic devices or nuclear reactors (just kidding, hopefully) are mined, refined, and used will find systematically presented answers in these volumes. Along with close-up photos of both raw ores and pure specimens, the illustrations include a view of an open pit or other type of mine, glimpses of forges or other factory scenes, and samples of manufactured goods. Most conclude with a summarizing chart of distinctive properties or products; Uranium also mentions in passing the dangers of nuclear power generation.
