Tri-County Science and Technology Fair

The Tri-County Science and Technology Fair was founded in 1990 by the Putnam Children's Discovery Center, a volunteer organization. The original fair was a countywide competition for Putnam County. In 1993, the Fair expanded to a regional Fair to include Westchester and Rockland Counties. The Fair's primary purpose is to reward children who have an interest in science, math and technology.

There are nine categories: Biology, Chemistry, Environment, Earth/Space, Engineering/Technology, Health & Medicine, Math/Computers, Physics and Psychology.
