Scientists do some of the most important and interesting work in our society, and try to find answers to questions by observing and doing experiments. They then think about what they observe and the results of their experiments. Sometimes they get a definite answer to their questions; sometimes the results lead to new questions and new experiments. As this process goes on, they understand more and more. The Science Fair will give you a chance to actually do the kind of things scientists do. You will find out that it really is possible to ask questions about our world and get answers to those questions. And most of all, you will learn a lot and have fun doing it.

What to Expect During the Fair
1. Please remember that the judges are volunteering their time. Their decisions will be based on their bestjudgment and Science Fair guidelines and will be final.
2. Be aware that the judges appreciate a display that clearly shows the intent and results of experimentation, and a presentation that concisely describes what was done and what was concluded. The judges want to feel that you are familiar enough with your project to discuss it comfortably and answer questions about it. Memorized speeches or rambling descriptions of trivial details hinder the work of judges, who need to be able to pose good questions in order to thoroughly understand the project. If you work on a team project, the judges will expect more substantial science.
3. You should prepare an oral summary of important points that you can present in no more than 60 seconds. Your judges will already have read your abstract, so if you've done a good job there your summary will remind them of questions that occurred to them earlier.
4. Following your summary, you may find it useful to present several prepared short descriptions of important aspects of your project. You know your project better than anyone, so you should have the best ideas of what is important. You should prepare answers for such questions as "Where did you get the idea for this project?" "What is special or distinctive about your project?" "What is the next thing you would do with your results?" "What questions has your project now generated?" You might also prepare for the questions you hope the judges will ask.
5. For team projects, one person could act as the team spokesperson and present the oral summary or this job could be shared among the team members. In any case, all team members should understand their roles clearly and be able to carry them out. This summary should include the rationale for the project being a group, rather than an individual, enterprise, and how each member contributed. Each member of the group should be fully knowledgeable about the project and be prepared to discuss his/her part.
6. You will be interviewed by at least two different judges for your category who will spend about five to eight minutes discussing your project with you. The judges may talk to you one at a time or in groups. It is difficult to space these interviews equally, so don't get discouraged if there is a long wait between judges. Don't worry about comparing the number of your judging sessions with your neighbors. You, or they, may be getting Special and Recognition Awards interviews.
7. Many judges prefer to learn about your project by asking questions. Be prepared for them to interrupt your presentation.
8. You probably will not be able to predict all of the questions you will be asked. Some of the judges are experts in their fields, so they may ask you questions you cannot answer. Don't let this bother you. Just answer truthfully and to the best of your ability. If you don't know the answer to a question, say so. DO NOT try to "snow" or bluff a judge.
9. The Kern County Regional Science Fair is a major local event. Your interviews with the judges might be covered by newspaper reporters (some with photographers), radio reporters, TV cameras (with their bright lights) and others. Videos might be used in promotional materials for future science fairs. The above section was adapted and revised from material first prepared for the California State Science Fair.
