Welcome to the virtual 2021 SARSEF Science and Engineering Fair

Over 50,800 K-12 students in Southern Arizona currently participate in SARSEF, conducting research projects to be considered as a representative of their school. The top 15% of projects advance to this weeklong celebration of their achievements and further competition.

Each year, over $100,000 in awards, trips and scholarships are awarded, thanks to our community support. Top high school students move on to international levels of competition, where SARSEF alumni succeed at four-times the national average!

SARSEF was formed in 1955 in an effort to increase student interest in the field of science. The mission of SARSEF is to teach Arizona’s Pre-K-12 grade students critical thinking and problem-solving skills as they participate in Science, Technology, Engineering, and Math (STEM) through inquiry-based learning and research. SARSEF accomplishes this mission through a variety of programming including SARSEF Research Fair Week, educational outreach programs with an emphasis on underrepresented populations in the sciences, teacher professional development, ACES Camp for Middle School girls, Racing the Sun, and Arizona STEM Adventure. Over 795 professionals in the community volunteer for SARSEF each year, and 145 organizations support its programs financially.
