Explore Gravity!: With 25 Great Projects    by Cindy Blobaum & Bryan Stone Order:  USA  Can Nomad, 2013 (2013) Softcover, e-Book     Reviewed by Bob Walch Did you know that whether you have a high belly button or a lower one can predict whether you will be a better swimmer or runner? Yup, it is all about one's center of gravity and your belly button indicates your center of gravity. This is just one of the amazing things you'll discover as you read this book about gravity, and how it impacts our lives. Along with the facts you'll learn about gravity, there are 25 hands-on projects that you can try at home or in the classroom that will make you more aware of this force that plays an important role in our lives and keeps the universe in place. You'll discover Words to Know that will increase your vocabulary, and Did You Know? boxes with interesting facts and illustrated instructions for each of the projects. Children between the ages of six and nine should be able to handle this book. The projects require some adult supervision but most of them can be completed using objects found in the home. If you wish to understand terminal velocity and centrifugal force, how the tides work, or how to make a simple scale, this is the resource you'll want to consult.
