Fair Participation Information
Students participating in the fair have put in a lot of hard work on their projects. It is important to make sure that all of the requirements of the San Mateo County STEM Fair have also been met. The Fair tries its best to align its requirements with that of the State Science Fair and national fairs such as the Thermo Fisher Junior Innovators Challenge. Please look over the requirements and tips below to make sure your are ready for the fair.
Important Information for the 2025 STEM Fair
-
The 2025 San Mateo County STEM Fair will be held virtually!
-
The San Mateo County STEM Fair is for students in grades 5-8.
-
High school students will not participate in the 2025 San Mateo County STEM Fair.
- The Alameda County Science and Engineering Fair will act as students local STEM Fair, and provide them with access to the California Science and Engineering Fair and International Science and Engineering Fair.
-
All students grades 5-8 will submit projects using one of the following Google Slides templates:
- For Engineering projects: Copy Engineering Project Template
- For all other projects: Copy Experimental Project Template
Students will be automatically forced to make a copy of the template.
-
All judging will take place virtually via Zoom, and judges will use your slide deck, in lieu of a tri-fold project board, to judge your project.
-
All 6th - 8th grade students who are selected for the interview phase will be notified on March 10, 2025. 5th grade students will not participate in the virtual Fair as this is their initial foray into the STEM Fair world. 5th grade students will receive feedback on their project that will further prepare them for their full participation in grades 6th - 8th.

Project Categories
The San Mateo County STEM Fair project categories are aligned to the four Disciplinary Core Ideas (DCI) from the Next Generation Science Standards. They are also compatible with San Francisco Bay Area Science Fair categories and the California State Science Fair categories.
Each Disciplinary Core Idea has one or more STEM Fair Categories. Each category has a brief description and Examples of project titles. Please note that it is the teachers' responsibility to determine the appropriate category for each students project. However, the fair director has the discretionary right to re-classify projects if they are not categorized correctly.
