When the tree house detectives hear a report on KSNN about a young inventor's contest, they decide it might be their next case. Thus begins The Case of the "Wright" Invention. The tree house detectives are not even quite sure what an invention is, much less how to create one. Seeking some advice, they visit Dr. D, a retired science professor, who helps the tree house detectives understand that the process of invention is similar to the scientific method. Armed with new confidence, they set out to create a "bug" list of ideas to find a problem to solve! As the tree house detectives learn about inventors, they get a little help from mysterious sources, Orville and Wilbur Wright. The tree house detectives are not sure whether these brothers are real or just actors. The tree house detectives also visit a young inventor, Lindsey Clements, who shows them that even kids can be inventors. NASA researchers and other community experts also help the tree house detectives learn how to plan, design, build, and test their invention. They discover that inventing is not as easy as they thought, even for Orville and Wilbur Wright. For more information visit their web site at http://scifiles.larc.nasa.gov
