Full of easy-to-do experiments and descriptive illustrations, each book in the series focuses on a certain aspect of science. From magnetism and electricity to chemical reactions, the inventive experiments help transform complicated theories and concepts into easily understood ideas. Supports the national science education standards Unifying Concepts and Processes: Systems, Order, and Organization; Unifying Concepts and Processes: Evidence, Models, and Explanation; Unifying Concepts and Processes: Constancy, Change, and Measurement; Unifying Concepts and Processes: Form and Function; Science as Inquiry; and Physical Science as outlined by the National Academics of Science and endorsed by the National Science Teachers Association. When you increase or decrease the temperature of something, why does it change form--like when water melts or freezes? How does the human stomach digest food and turn it into energy? The answers to these questions and more are revealed through fun, easy-to-do experiments.
