Welcome to STEM Expo!

More than just a Science Fair:
STEM Expo is an alternative concept to the typical Science Fair - striving to give students a place to exhibit their work alongside entertainment and learning opportunities for the whole family – including STEM based activities and interactive exhibits from local scientists, organizations, schools, and companies. Read a lot of details about STEM Expo at our "What Is STEM Expo" page, or read about the categories here.

Placer County STEM Expo has been cancelled.

It is with deep regret that we must announce the cancellation of Placer County STEM Expo.

STEM Expo, as an organization, is still here! We still support the innovation of this alternative to the typical science fair, just - unfortunately - not in Placer County, California
