By Ed Sobey. More than 30 demonstrations of 16 model craft are outlined here in illustrated, reproducible how-to handouts that list materials, describe procedures, and explain scientific principles. A soda-can engine, balloon-powered rockets and rocket cars, air-jet propulsion, pump rockets, and "implosions and explosions even your mother will like" are all on the menu in a book that aims to "convince the kids that they are rocket scientists and the rocket scientists that they are kids." Grades 4–9. Index. Glossary. Suggested resources. 8½" x 11". Good Year Books. 106 pages. ©2006. GDY442.
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.
