Delaware Valley Science Fairs, Inc., seeks to stimulate interest in inquiry-based STEM among middle- and high-school students. Stimulating interest in inquiry-based Science, Technology, Engineering and Mathematics (STEM) among middle-school and high-school students Founded in 1949, Delaware Valley Science Fairs (DVSF) strives 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. DVSF, a 501(c)3 organization, enables students in middle and high schools to develop a love of science, to encourage their interest at this stage in their lives, to help them gain confidence and, finally, to move into careers in science or engineering. DVSF year-round programs provide opportunities to inspire the next generation of innovators and support students, mentors, and teachers in Eastern Pennsylvania, Delaware, and Southern New Jersey. The philosophy behind our programs is that students learn science by doing science.
