Series Made Simple
Imparting just a few tantalizing morsels of information about various kinds of large-scale infrastructure, these primary-level introductions combine particularly vivid photos with comments that are simply phrased but not entirely generalized. In Bridges, for instance, Pettiford identifies and points out distinctive features of common kinds: beam, arch, and suspension. Also worth noting are photographic depictions of woman engineers and designers at work in Bridges, Dams, Skyscrapers, and Roller Coasters. Less laudable are the single hands-on projects that close each volume, which are perfunctory instructions for such nonstarters as a dam made from rocks and sticks in a flat pan full of sand. VERDICT Possible additions to STEM collections.
