Science Fair

The Why:

The purpose of our Mendocino County Science Fair is to stimulate in young people an active interest in science and encourage them to apply creative and critical thought to the solution of scientific problems, and to foster school and community cooperation in developing the scientific potential of students in Mendocino County, and to give recognition for the work students have done. 

As a result of the ongoing pandemic, MCOE is offering a virtual science fair this year.  The exhibition and awards ceremony will take place on our zFairs site on March 20, 2021.


Mendocino County Office of Education is inviting all Mendocino County Student Scientists who wish to compete in the 35th annual county-wide science and engineering fair to upload their project onto our Virtual Platform.  Your deadline to submit projects is March 7, judging will take place between March 18-20, and our public virtual exhibition and awards ceremony will take place on March 20, 2021, when we will select the finalists for the State fair to take place on April 12-13, 2021.

How to Participate:

● All entries must be uploaded by Sunday, March 7, 2021, by 11:59 pm. If you have any difficulty uploading or submitting your project, please be sure to get assistance from your school and/or Local Science Fair Coordinator before the deadline. 

○ Include a caption that describes the experiment. Please include where the experiment was conducted. 

○ Be sure submitted videos and photographs conform to your school media policies regarding the publication of identifiable students. And please read the “further details” below about how your images might be used.

Further Details:

If you are already designated as the Local District Event Coordinator, MCOE is offering a webinar on January 19, 2021, to walk you through creating a site on Z-fairs, and supporting your students to upload projects to the site.

Mendocino County Office of Education staff will use the established Scoring Rubrics for all projects.  Rubrics align with the International Science and Engineering Standards (ISEF) and will determine which projects are eligible to compete to represent our County at the State Science Fair. The Local Event Coordinators will be notified of the winners by the end of the day March 20th.

Submitted videos and photographs must conform to your local school media policies regarding the publication of identifiable students. By submitting this media to us, you are giving permission to the Mendocino County Office of Education to publish the videos and photographs.

All submitted projects will be uploaded and shared in an online gallery and the link will be available on the MCOE website later in the Spring.
