An original project deals with a subject that has not been proven or seen before. A useful project solves a problem and adds to the knowledge of science. An understandable project can be repeated in the future with similar results. Try to write a question that clearly outlines the project. Possible sources of information are libraries, teachers, television shows, newspapers and people who work in that area.
General information is available in encyclopedias.
For more specific information, books or science magazines are better. Excellence sources of very current data can most often be found on the Internet. Use index cards to write down all important information, keeping track of the source of information. It is essential that all science fair rules and regulations are read and understood by science fair participants so that accidents do not occur and that time is not wasted developing an unsuitable project. In particular, there are very specific and strict rules for projects dealing with animals or using humans in scientific research.
