This book includes models, experiments, activities, and project ideas relating to physics and the motion of objects.  It is intended for grades four through seven, but by differentiating the tasks described, it could be used for second and third graders as well.  Step-by-step directions are provided for each of the 25 activities in the book, but students are encouraged to explore and test new ideas as they observe and analyze the experimental data.  The materials needed are, for the most part, common and inexpensive. The hands-on activities in this book help children learn through experiments and it keeps children engaged and interested in physics.
