Publisher's Synopsis
With new entries on nearly 500 current children's science books, Pilger's popular index now covers approximately 1,500 titles. A few of the subjects added or changed are biologic controls, bioremediation, and global warming. Many of the new activities are related to our society's impact on the environment and what we can do to protect or reclaim our resources. Experiments and activities are indexed by subject, described briefly, and given a location code. Subjects are extensively cross-indexed, and a separate alphabetical list of authors accompanies the book. This book provides a quick and convenient way to locate science experiments and activities for students in elementary through middle school.
