Continued publication is always dependent on funding. The journal is intended to serve as a vehicle to honor young investigators and their teach (1) ers by showcasing their work, motivating them to continue their involvement in research sci ence; a sourcebook for both students and teachers who are looking for ideas for research (2) projects, particularly in the areas of aviation and aerospace; and a volume to disseminate (3) student research discoveries. Each year, Van Nuys Airport Many abstracts included in the journal demonstrate good science, i.e. clear introductions will provide special recogni describing hypothesis to be tested, methods, results and conclusion statements, and - most tion and awards to the best important- sufficient numbers of appropriate control and experimental samples and repeti published aviation- or aero tions of experiments. Other abstracts do not display one or more of the principles of perfect space-related abstract (as science. The journal does not eliminate abstracts that do not demonstrate perfect science; the selected by the journal editor) editor, however, reviews all abstracts and reserves the right not to publish those that are seri ously flawed. The journal does not notify authors if their abstracts have been deleted. in three categories: elementary school (grades Some of the abstracts are experimental plans instead of completed projects.
