Base Jumping

Gr 4–6—Centered around a theme of action-packed sports (some of which could be dangerous without proper precaution), these volumes draw upon science principles and introduce new vocabulary as well as information. Because many readers will not have experienced many of these sports, each title begins with a quick overview. "Test It!" text boxes mention a science principle and suggest simple experiments. For example, in Mountain Climbing, one sidebar explains how to determine the slope of a mountain using a protractor. Black-and-white photos, reproductions, and color action shots illustrate the spreads. Those that focus on language and jargon introduce popular phrases from each sport (short language quizzes help readers look for meaning in context), and final pages deliver charts and information about rick-taking stars. Children can expand their knowledge in these little-known areas by using this set. Consider purchasing if the "Sports on the Edge!" series (Marshall Cavendish, 2011) is popular.
