From The CriticsDry ice has provided eerie special effects for a variety of visual media over the years. In this book, dry ice becomes the equally engaging focus for scientific investigation at the middle school level. The book is a Lawrence Hall of Science GEMS product that provides teachers with a complete guide to using dry ice to develop students' scientific investigation skills, as well as to explore the particulate nature of matter, states of matter, and the role of energy in phase changes. A teacher may select a strand that emphasizes chemical concepts, or one on conducting investigations, or piece on developing a scientific mind-set. The activities are carefully written and sequenced and have been tested and refined in the classroom. The guide includes complete lists of materials and reproducible sheets for segments of the activities, overheads, and student science journal pages.
An additional strength of the volume is the wealth of supporting and supplemental information it offers. The writing team provides information on science processing skills; concept development; misconceptions associated with the target concepts; suggestions for assessment; scientific background information on dry ice, phase changes, and the particulate nature of matter; resources for locating, storing, and handling dry ice; science education and chemical reference materials; and children's books to make a literature connection. Actual student journal entries, pictures, diagrams, and limericks enhance the guide and provide creative suggestions for receptive teachers. Because of its scope, this book would make an excellent addition to a teacher's personal or professional library. Highly Recommended, Grades 5-8.REVIEWER: Dr. Barbara A.
