The OSSEF Display and Safety Committee is the final authority on display and safety issues for projects approved by the SRC to compete in the OSSEF. Occasionally, the OSSEF Display and Safety Committee may require students to make revisions in their display to conform to display and safety regulations.  The regulations that follow have been divided into main categories that are required rules and further general rules.  The International Rules for Pre-college Science Research-Guidelines for Science and Engineering Fairs.pdf is published annually to support students doing independent research safely.  They are the official rules of the Intel ISEF and students competing at a Society-affiliated science fair such as OSSEF. 

The purpose of these rules is to:

  • protect the rights and welfare of the student researcher
  • protect the rights and welfare of the human participant 
  • ensure adherence to federal regulations
  • ensure the use of safe laboratory practices
  • protect the environment
  • determine eligibility for competition in the Intel ISEF 2019

The following regulations must be adhered to when a student exhibits a project at OSSEF.

A full review of rules can be found for each section listed below at the designated link.

Other Display Regulations
No changes, modifications, or additions to projects may be made after approval by the Display and Safety Committee. Finalists who do not adhere to the signed agreement on the SRC/DS2 Form regarding this regulation will fail to qualify for the competition.

  • A project data book and research paper are not required but are highly recommended.
  • If a project fails to qualify and is not removed by the finalist, Fair Director will remove the project in the safest manner possible but is not responsible for damage to the project.

Other Safety Regulations

  • Any inadequately insulated apparatus producing extreme temperatures that may cause physical burns is not allowed.
  • Any apparatus with unshielded belts, pulleys, chains, or moving parts with tension or pinch points must be for display only.
  • The OSSEF Director and/or the Display and Safety Committee reserve the right to remove any project for safety reasons or to protect the integrity of OSSEF and its rules and regulations.
  • Project sounds, lights, odors, or any other display items must not be distracting. Exceptions to this rule may be permitted for judging demonstrations. Approval must be given prior to judging.

Other OSSEF Information and Requirements

About OSSEF 

Oklahoma State University is the new host for the Oklahoma State Science and Engineering Fair (OSSEF). 

OSSEF will be held on March 28th, 29th, and 30th of 2019. OSSEF offers a number of special and category awards. In addition, four 9th-12th grade projects will advance to the International Science and Engineering Fair (ISEF) competition which will be held on May 12th-17th, 2019 in Phoenix, Arizona. Approximately 1,800 high school students from more than 75 countries, regions, and territories are awarded the opportunity to showcase their independent research and compete for on average $4 million in prizes at ISEF.  

Paramount to everything is ensuring that Oklahoma students have the opportunity to engage in scientific research and receive recognition for their outstanding efforts. To help support students and ensure the success of the OSSEF program, donations can be made to the Oklahoma State University OSSEF Foundation Fund. (link)

All students, parents, staff, and community members are invited to attend the OSSEF public viewing of the outstanding research projects on March 30th, 2019 from 6:00pm to 8:00pm at the OSU Endeavor Building.  

Public Display

All students, parents, staff, and community members are invited to attend the OSSEF public viewing of the outstanding research projects on March 30th, 2019 from 6:00pm to 8:00pm at the OSU Endeavor Building. 

What to Expect During the Fair

Thursday, March 28th: Project Setup and Clearance

12:00pm - 4:30pm

Step 1: Immediately upon arrival, report to Registration/Check-In table at the OSU Endeavor building which is located south of the OSU football stadium. 
1. Provide OSU-OSSEF staff with your grade and last name.
2. He/She will give you a Safety & Display Card that includes your name, division, category, and project number.
3. You will either be cleared to 
set up your
prior to receiving clearance.project or instructed to report to Ms. Lauren White to resolve issues with your paperwork prior to setting up. Note: You are NOT allowed to set up

Step 2: What is my project number and where do I set up?
1. The project number is printed on the label of the participant’s packet picked up at the registration table.
2. Locate the table/floor space with the sign containing the corresponding division and project number. Note: Do NOT remove or relocate the sign or any tape marking your designated area.

  • Division I Senior High projects are located on the second floor of the Endeavor building.
  • Division II Junior High projects are located on the third floor of the Endeavor Building. 

Step 3: How do I set up my project?
1. Set up the project within the boundaries of the assigned area Note: Do NOT remove or relocate the sign or the tape marking your designated area.
2. DO NOT climb or stand on the tables for any reason.

Step 4: Get project cleared by Safety & Display Committee
1. Fill out the Safety & Display card provided at check-in.
2. Find a member of the Safety & Display Committee.
   o This person will check the project for adherence to the Safety and Display Rules.
   o He/She will clear the project for display and place a Safety & Display Approval Form on the project.
   o He/She will sign the Safety & Display Card designating final approval if all criteria are met.
3. Be assured that we will be happy to work with you to see that the project looks its best and still satisfies all the rules. If the project has a problem, don’t panic. We can probably work out some solution.
