This book contains kid-tested cool projects that use physics to propel things and will inspire young science buffs to experiment with their own ideas. Kids will learn how to Observe, Hypothesize, Test, and draw a Conclusion by using The Scientific Method. Included with the experiments are detailed step-by-step instructions with original photography, material lists, an explanation of the science behind the fun, real-world applications of the principles behind the project, tips and project variations, and suggestions of what to keep track of in a science journal. A glossary and index is also included.
