Editorial Reviews

Gr 3-5– In these introductions, six four-page chapters include stories about the inventions or discoveries, biographies of the person(s) involved, simple science experiments related to the inventions, and short narratives about the current use of the items. Speech bubbles designed to convey the scientists’ comments flow from the painting of the featured person. Information in them is sometimes vague. Some of the textual statements suffer from the same affliction as a result of oversimplification, while some facts are incorrect. Construction, for example, discusses flat shapes, which are not defined, and it is not clear as to how “Towers are drilled into rock or concrete blocks” when building a suspension bridge. Space leads readers to believe that Russian scientist Sergei Korolev launched Sputnik I by himself. Also, the random arrangement of topics can be confusing. After an abrupt ending, a bubble-type time line, which includes information that is not in the texts, concludes each volume. A disappointing series.
