Thank You to the many Science Fair Judges and Judging Teams for providing important feedback and encouragement. You are helping to foster STEM literacy and competency in the next generation of STEM professionals and advocates, scientists, researchers, inventors, and engineers.

To our sponsors—Bayer, Boeing, the Broadcom Foundation, and Missouri MOST529, and the many Special Award Donors, without you, one of the nation's largest, free, regional K-12 STEM Fairs would hardly be possible.  Thank you for your investment in the region's future and the futures of today's students!
