Gr 6-10-Collard mixes science with personal narrative so that the scientists who study the life-forms surrounding the Great Barrier Reef are humanized and the reasons behind their research are combined with real-life experiences. The text is often written in a suspenseful manner, and is likely to attract students. The writing is clear, and should appeal to reluctant readers. While the narrative style doesn't lend itself to serious research, the index is comprehensive, thus leading readers to specific subjects. The text is sprinkled with black-and-white photos, many small and not of good contrast, and there are two sections of full-color photos. The illustrations help illuminate some of the material covered. A good tie-in to units on sea life or Australia.-Laura Younkin, Ballard High School, Louisville, KY Copyright 2001 Cahners Business Information.
