Ethics Policy Scientific fraud and misconduct are not condoned at any level of research or competition. This includes plagiarism, forgery, use or presentation of other researcher’s work as one’s own and fabrication of data. Fraudulent projects will fail to qualify for competition in affiliated fairs, TCRSF and ISEF. Society for Science & the Public reserves the right to revoke recognition of a project subsequently found to have been fraudulent.

About Us

NEW: TCRSF now covers NINE counties of Minnesota! Students who attend school (public, private, charter, home school) in Hennepin, Ramsey, Washington, Dakota, Anoka, Chisago, Isanti, Sherburne, and Wright Counties who are in grades 6-12 are invited to participate. There are three ways for a student to participate in the Twin Cities Regional Science Fairs:

  • Participate in a school science fair and be chosen to advance to the regional fair, or
  • Participate in a Minnesota Academy of Science-Affiliated Science Club, or
  • Obtain teacher or the adult project mentor approval and recommendation to compete at the regional level. You may also contact us directly at if you have questions about entering the regional fair directly. If you contact us directly, please provide your name, grade level (grade 6-12) and your research plan, or a short description of your project or experiment.

Student participants in the science fair can compete in the project competition (grades 6-12) and are also encouraged to participate in the research paper competition (grades 6-12) using the same experimental work.

The Twin Cities Regional Science Fairs sends winning students from grades 6-12 on to the Minnesota State Science and Engineering Fair, a program of the Minnesota Academy of Science, as well as to the International Science and Engineering Fair (ISEF) (grades 9-12 only) and Broadcom MASTERS™ Competition (grades 6-8 only). If you have questions about how to participate in the science fair, please contact the Fair Director at

The first Twin Cities Regional Science Fair was held in 1939.

Public Display

Open to the Public will be available online Saturday, February 27, 2021. You will need to be logged in to view the student exhibits (Student, Teacher, Judge, Staff, Volunteer, Attendee).

All who are logged in to may see the other virtual exhibits.

Go to the Fair tab at the top, then pull down to Showcase. Give it a minute to load. You may see videos, PDFs, abstracts, and so on from each project. You may search for key words, or student names, or by category.

When you are done, click on Home or on the 9-County logo to go back to the Home page. Enjoy the Showcase!

What to Expect During the Virtual Fair

The research paper competition will be held online where judges will read and score the students' research papers. The registration for research papers and judging of research papers will occur on  Comments by judges will be available for students a few days before the in-person virtual judging of projects.

The project competition will be held online with round 1 of judging will be reviewing the materials uploaded by the student (after uploads are approved by the Display and Safety team). The student is not present for round 1.  Round 2 of judging will be similar to the students waiting for the judges during judging at the fair - but the student will be in a virtual room ready to answer judges questions. The judges will already have reviewed the project materials, and so may go straight to questions about the project. Expect that there will be about 2 to 5 judges per session. Special awards judges may add in to your judging session or may stop in when you are not talking to other judges. Relax, have fun, answer judges questions as you tell your story. Students: you are the expert on your project!

We are planning to have a virtual awards ceremony - and will need to mail you your awards, so make sure that you have registered with your correct address, email that you can receive from emails outside your school, and a phone number at which we could reach you.

Monday, Feb.15 - all project materials and SRC form fixes must be done. Your presentation video URL must be entered and saved.You can test it by logging in, going to Fair tab, Showcase page, then find your project and see how it looks. Try the hotlinks! Students/teachers - make sure you have credited your photos, diagrams, charts, and graphs in your display! It is also a GREAT IDEA to upload a school or other photo with your parents permission to put a face to the work the judges will be judging.

Tuesday Feb 16 - Thursday Feb. 18 - Display and Safety inspection of all projects. (Students are not present for virtual inspection.)

Friday, Feb. 19 - Wednesday, Feb. 24  Both scoring judges and special awards judges will be looking at student exhibits and videos and research papers if they were uploaded into the project exhibit. Students - just relax here! This all goes on without you.

Thursday, Feb. 25 - Watch your email for details. We may try to schedule a short practice round - no scores - so students and judges can test the video interface to make sure they will be able to connect.

FRIDAY, Feb. 26 - Just like for the in-person fair, judges will get to talk to students about the students' projects. Students: the judges have already reviewed your exhibit... so now is the time to interact, answer questions, ask questions, and have fun talking about your project (but not repeating the video presentation). This is likely 4 PM CST to done before 9 PM. We are trying to see if we can build a schedule so we can cut it down to only about 3 hours. Watch your email (likely on Thursday, Feb. 25)

Saturday Feb 27 Exhibits are Open to the Public

Sunday Feb. 28 Awards program online 1 PM

Monday, March 1 in the evening we will certify our ISEF Finalists. This will be of interest to students who are alternates and announced to be ISEF finalists and their parents. Those announced at the Awards program are NOT certified until during this March 1st virtual meeting.

In March, awards will be mailed to the students' home addresses from in their registration.

Bi-directional in concept, projects can be those developed through basic research moving toward clinical testing (bench-to-bedside) or projects that provide feedback about the applications of new treatments and how they can be improved (beside-to-bench).

Judge Criteria

We have two kinds of judges.  

  1. Ribbon Judges: All projects will have judges that are scoring their project according to our scoring rubric which is available on our website (Judging Criteria). This is the same rubric as is used at state science fair.
  2. Special Awards Judges: There are special awards judges who are selecting projects based on the criteria for the award. Any project many win a special award regardless of their ribbon score, if they happen to best match the award criteria. These special awards come from 3 areas:
    1. Regional affiliated awards from our affiliations with international
    2. Sponsor awards which are in honor of the annual financial donations that pay for 80% of the costs of running Twin Cities Regional Science Fairs (registration fees cover only about 17% of our annual budget). Remember, we are an ALL-volunteer 501c3 educational nonprofit, so our sponsors are donating directly into the costs of this youth program!
    3. Awards from Individuals/Groups.

We ask that our High School judges have a minimum of a science or engineering bachelor's degree, or six years of science/engineering work experience.  We prefer that our middle school judges meet the same criteria, but we will permit upper division undergraduates to judge 6th and 7th grade.

No parents or teachers may judge in the division (middle school or high school) in which they have students competing. If you have students in both, please consider volunteering for another position. We still need your help and there are many jobs that you could do!

Judge score sheets (grading rubrics) are provided below for your information. We provide the score sheets at the fair for the judges. Students: review these score sheets in advance to know the grading standard!
