The Dr. Nelson Ying Orange County Science Exposition is a 501(c)(3) educational, non-profit organization that operates exclusively for the promotion of science in middle and high school students within Orange County, Florida. We pursue this goal by organizing a science education competition (more commonly referred to as a science fair) for Orange County students. Our science fair is affiliated both with the Florida State Science and Engineering Fair and the Intel International Science and Engineering Fair, a program of Society for Science & the Public. As a result, winning students from our competition move on to state and international competitions.

Our costs are wholly subsidized by contributions from private individuals and companies. Other than the in-kind contributions we do not receive any funds from either the public school system or any other governmental unit.

We solicit and accept four types of donations:
