Welcome to the Dr. Nelson Ying Orange County Science Exposition web site.
The Dr. Nelson Ying Orange County Science Exposition (Ying Expo) has been named after its major donor, Dr. Nelson Ying, Sr. The Ying Expo is open to all public, private and home-schooled students throughout and within Orange County, Florida. We are affiliated with the Florida State Science and Engineering Fair and the Intel International Science and Engineering Fair.
Within this site we have included as much information and material as possible to assist teachers, parents and students participating in the Ying Expo which will be held at Rollins College on February 8-9, 2015.
