The total 4,895 works presented at Science Fairs for the past 17 years(1986∼2002) are classified by subjects and participators, and the 1,277 works in biology section are analyzed by participators, contents, and object materials. The results are as follows: The proportion of exhibits according to sections was the most in Biology(26.1％). The social position of exhibitors and its proportion were 45.7% in students and 54.3% in teachers and popular people.
