Why STEAM Expo?

More than just a Science Fair, the Tuolumne County STEAM Expo offers a place for students to exhibit their work alongside entertainment and learning opportunities for the entire family. We allow young minds to experience an innovative environment of hands-on science. The STEAM Expo enables students to explore their interests and talents by offering six elective categories from which students can choose: Science Fiction Writing, Scientific Illustration/Nature Notebooking, Rube Goldberg Devices, Biomimicry, Engineering Design Process, and Scientific Inquiry.

Students can compete with their projects or display them for viewing and evaluation. Collaborative groups are permitted to work on projects together, and in the non-competitive arena, whole class projects are welcomed.

In addition, we are proud to be the official county affiliate for the California Science & Engineering Fair (CSEF). A sixth through twelfth-grade student’s entry into the Scientific Inquiry Project category can lead to recognition as one of California’s top young scientists or engineers.

The Tuolumne County STEAM Expo is designed to:

  • Motivate and stimulate the interests of ALL students in all grades in the STEM fields: Science, Technology, Engineering, & Mathematics. Creativity and Art are expected to be integrated into the projects.
  • Recognize the achievements and efforts of students in STEM.
  • Identify exemplary projects that will advance to the California Science and Engineering Fair.
  • Stimulate interest and support of grade-level appropriate STEAM integration within our schools.
