Delaware Valley Science Fairs

Delaware Valley Science Fairs, Inc. (DVSF) was founded in 1949 and incorporated as a non-profit, 501(c)(3) organization in 1993, making it one of the oldest Fairs in the country. It is now also one of the largest.  The Fairs were designed as a vehicle for stimulating interest in Science, Technology, Engineering and Mathematics (STEM) among students in middle and high schools in the tri-state area.  The philosophy behind the Fairs is that students learn science by doing science. DVSF provides an opportunity for students to excel and reach their full potential fostering intellectual curiosity and creative problem solving - essential skills for future innovation.

Our Mission is to  bring parents, teachers, and industry together to stimulate and nurture young people so that they grow and develop into contributing members of the community.

We provide a forum for students to present their scientific work and interact with scientists in their field to receive feedback on their efforts. Students are awarded, scholarships, cash prizes, and other non-monetary recognition for outstanding work. We provide mentoring and teacher training to facilitate participation in this activity.

DVSF presents over $2,000,000 in awards and scholarships.

DVSF is an Affiliated Fair for the Intel International Science and Engineering Fair (ISEF)
