This is the second edition of Marvin N. Tolman’s bestselling book Hands-On Physical Science Activities for Grades K-6. Like all the books in The Science Problem-Solving Curriculum Library series, this revised edition offers compelling activities that help teach students thinking and reasoning skills along with basic science concepts and facts. The book’s activities follow the discovery/inquiry approach and encourage students to analyze, synthesize, and infer based on their own hands-on experiences. This new edition includes an expanded Teacher Information section, inquiry-based models and complex cooperative learning projects using materials found around the home. Many of the activities easily become great science fair ideas as well as activities that correlate with the national standards. Designed to be user friendly, the book includes 175 easy-to-use, hands on activities and is organized into eight sections:   Nature of Matter Energy Light Sound Simple Machines Magnetism Static Electricity Current Electricity
