There has been some evidence that students who develop projects for science fairs continue their interest in science through high school and beyond. Local and regional fairs generally are slated as a prelude to state science fairs and the International Science and Engineering Fair (ISEF). Organizing a district science fair requires informed leadership by the school board and professional staff working together toward the achievement of established curricular goals. Committees to organize science fairs generally include school personnel and community representatives from business and professional science organizations. The committees should address fundraising, award solicitations, selection of judges, site arrangements, publicity, and application approval. After the fair is over, thank-you notes should be sent to sponsors, award donors, and judges. Finally, an evaluation of the fair should be made by the committee, with formal and/or informal input from the judges, sponsors, participants, teachers, and attendees. (MLF)
