T is for a Time Alphabet uses poetry and expository text to explore the concept of time, from explaining basic units of measurement to showcasing important scientific achievements. Topics include famous inventors (Albert Einstein and John Harrison) and important structures and landmarks (Kulkulkan Pyramid and Big Ben). Budding scientists will discover what world-famous stone structure is believed to be an early calendar, follow the voyages of explorer Ferdinand Magellan to better understand the International Date Line, and learn to tell time using the Zulu time system. Gr 2–5—This title offers an overview of concepts related to time, listed in alphabetical order: "A is for Almanac," "D is for Daylight Saving," "E is for Einstein," "G is for Greenwich Mean Time," and "K is for Kukulcan Pyramid." Accompanied by sweet, painterly illustrations that hark back to earlier eras, the entries begin with four-line rhymes and go on to clear, well-researched prose explanations, rendered in a fairly small typeface. These are simple and brief introductions to a mix of basic ideas (such as explanations of a week, a shadow, and the night sky) and much more challenging concepts (definitions of Zulu time and verge escapement). Other books in this series are geared to readers ages six to 10, but this title defies categorization: some content is straightforward, but much of it is too sophisticated for primary students.
