SiS Annual
STEM Celebration
A free, hands-on STEM fair where students ages 5–15 and their families get to explore real experiments, meet real scientists, and discover what makes STEM worth getting excited about.
Where curiosity meets hands-on science
This is the event that started Sisters in STEM, and it remains the heart of what we do. Every year at Saguaro High School in Scottsdale, students ages 5–15 and their families explore stations run by our high school volunteers and local STEM professionals, all completely free.
From chemistry and engineering to coding and robotics, the celebration covers every corner of STEM. No experience needed, just curiosity. Whether you're five or fifteen, a first-timer or a returning fan, you belong here.

Sponsor the event
This event is free because of our sponsors, and every contribution makes a real difference. Whether you want to run a booth, donate materials, or support us financially, we want to hear from you.
