SECOND EDITION

Throughout the writing of this book, I have daydreamed about the fun I have teaching hands-on physics. I've pictured children and educators enjoying these science activities, while reading instructions that are clear and easy to follow and simple explanations about what happened and why. Science safety was a primary concern when designing the activities in this book. It is my fervent hope that this physics book will ignite a profound curiosity for scientific discovery in readers of all ages. The bottom line is that I want to share my passion for physics and how exciting and relevant science is to our everyday lives.

One doesn't need a degree in science to benefit from learning more about why magnets stick to the fridge door and not to a wooden door. Wonder how a parachute works? Why does a magnifying glass make things look bigger? I imagine children of all ages stopping and questioning the physical world around us. Scientific investigations help develop patterns and higher-level thinking to solve real, everyday problems.

The order of presentation is designed to provide a physics foundation upon which to build new principles of science. The activities in each specific topic spiral in content. Throughout the activities, certain words and phrases are in bold; the meanings of these are given in the Glossary at the end of the book. Working through the activities in order is suggested. However, any activity has educational value on its own merit. With the help of the Glossary, as well as introductions for various topics, you can pick and choose any investigation and be rewarded with a successful experiment. Of course, a good outcome depends upon following the procedure steps in order. Substituting equipment can affect the results for some activities, but science is meant to be fun so trust your judgment about changes.
