Learn all about flight with the science activities. Kids will eagerly soar into the wonderful world of aerodynamics when they build the spinning, flying, rocketing creations described in this book. There are 69 science demonstrations and projects to construct and test, from boomerangs and water rocket launchers to homemade hovercrafts. Many of the experiments can be extended to become topics for school science fairs using the author's easy-to-follow suggestions. Icons alongside each model explain the physical principles involved, while troubleshooting tips keep the experiments running smoothly. It also includes a timeline of major flight achievements. Water science activities for home, school, and the beach! Ed Sobey helps kids explore the wonderful world of water with 69 lively hands-on projects for the beach, swimming pool, and kitchen sink. Using everyday materials, he combines the fun of water games and toys with the scientific concepts behind water pressure, hydro-power, and other key principles. These activities can be expanded into science fair entries too. Not only are the physical principles explained but special demonstration and troubleshooting tips are included to ensure hours of fun.

Ed is curious - he wants to see the world and understand how it works. So he travels (a lot) and takes things apart. And, he enjoys putting things together from building robots to writing books.
As a math and physics major, Ed likes numbers. He's traveled to 61 countries on all 7 continents. He has directed 5 museums (including the National Inventors Hall of Fame and founding the National Toy Hall of Fame) and written more than two dozen books.
He holds a Ph.D. in oceanography and has participated in 20 some expeditions, including doing research on sea ice in Antarctica. With his wife, he has sailed across the Pacific Ocean and has done a circumnavigation teaching oceanography for Semester at Sea. Ed is a Fellow Emeritus in The Explorers Club.
An avid outdoors person, Ed runs, bikes, swims, kayaks, and SCUBA dives. Along the way he searches for the unusual gizmo to take apart or at least figure out how it works.
