Rules & Regulations

The following regulations will help keep the projects uniform and within the laws of the Education Code of the State of California.  Science Fair sponsors want all students to have the best opportunity to compete for the annual awards.  During the time that the Science Fair is open to the general public, the perception of the projects must be positive and precautions must be taken for the security of each project.  All projects at the Los Angeles County Science Fair must abide by the following:

1.   Present an experimentally based research design exemplifying a scientific methodology. Non-experimental projects which may be overlooked at registration and entered will be judged using the criteria for experimental projects and will be at a great disadvantage.

2.   Be carefully prescreened by the individual school’s Science Fair sponsor and the teacher whose student is submitting the project. The Los Angeles County Science Fair Judges Worksheet lists the criteria used to evaluate the projects.

3.   Clearly distinguished between the work of the student entrant and the work of others. Students who have prepared a project in conjunction with research participation opportunity in industry, a university, hospital or institution other then their school must show only the student’s research in their project display.  Students may mention the relationship to the research of others in notebooks only if they clearly specify the assistance received and the role and contributions of others in research related to the project. It is highly recommended that projects of this kind be accompanied by a letter from the principal research director indicating the relationship of the student project.

4.   Be original and distinct.  Identical project/data may not be submitted by a school under separate judging divisions. Likewise, the same unmodified project can not be submitted multiple years.

5.   Be within the total quota for each school.  Quotas will be announced in advance of the Science Fair. If additional applications are submitted, schools will be contacted and each school will determine which projects are the official entries. If excess entries are initially overlooked, only a number corresponding to the quota will be judged. Those to be judged will then be selected at the discretion of the Science Fair Committee.

6.   Be entered in the Fair after an application is sent.  Schools should avoid sending applications for projects until it is certain that the projects will be completed in time and will physically arrive at the Science Fair. Projects, for which we receive a registration, but are not actually entered, create errors in the program, a waste of time for judges and leave unsightly open spaces in the exhibit area. The Fair Committee will reduce the project quota for any school that fails to produce the project for which we have received a registration.

7.   Be submitted by students only in grades 6-12 or with an age equivalent to those in grades 6-12. Younger students may submit only if they are in an accelerated program with certified enrollment in grade 6 or higher level subjects.

8.   Be entered at the Science Fair and picked up only within the designated hours. Early entries will not be accepted.  Entries will be accepted and project removal will be permitted only when a member of the Los Angeles County Science Fair Committee is present. Facility staff members are not authorized to receive or permitted to pick up projects.

9.   Use illustrations of micro-organisms, animals and plants.  The display of bacterial cultures and live or preserved animals and plants will not be permitted.

10. Remain at the Fair during the days scheduled for public viewing.  The only exception to this rule is for students who must take projects to the International Fair, if their departure day/time overlaps the time that the Los Angeles County Science Fair is open.  To ensure security during project removal, the authorized time for pick up will be strictly followed. The Science Fair is not responsible for projects left after the designated time.

11.  Use a title which provides the viewer with a clear concept of the subject and procedure of the research.  Present the steps of the scientific methodology used, organized from left to right and top to bottom. Use metric units for all measurements. Have all values on charts and graphs correctly labeled.  Present all narrative writing in a legible manner with correct grammar, punctuation and spelling.  Carefully review the category descriptions and select the proper one for the project.

12.  Fit within the prescribed space limitations – no larger than 76 cm (30 inches deep (front to back), 122 cm (48 inches) wide (side to side) and 284 cm (108 inches) high (floor to top including height of table).  Oversized projects will be screened at the door and refused entry.

13.  Be able to support their weight and not collapse due to inadequate construction.  Any project which does not meet minimum standards for construction will be removed from the display area and not judged.

14.  Be careful to display photographs which do not show procedures detrimental to the health and well-being of vertebrate animals. (For instance, the performance or results of surgical procedures will not be shown.) Those not in compliance will be removed from the display areas and will not be judged.

15.  Have notebooks and small equipment items removed no later than the viewing period following the end of the awards ceremony.  The Science Fair will not be responsible if these items are missing from projects. Do not display items you cannot afford to lose.

16.  Do not have computers with projects for the preliminary judging. A computer may be brought by the student for the judging interview on the second day if the student assumes full responsibility for the computer. Judges are instructed to have students return for interviews if the computer demonstration is essential.

17.  Give attention to all considerations of safety. Projects which use 120 volt electrical current must have all wires and connections well shielded. Those not in compliance will be screened at the door and refused entry.

18.  Adhere to all of the rules and regulations of the Science Fair and all relevant federal, state and local laws. Those not in compliance will be screened at the door and refused entry.

19.  Be submitted with the understanding that the decisions of the Los Angeles County Science Fair Committee is final.


1.  If a student project requires electricity, the fair will provide one (1) outlet.  If additional outlets or surge protection is required, the student must provide these items.

2.  Projects that require 110 volt; 60 cycle supply will be allowed a MAXIMUM of 500 watts.

3.  Projects using 110 volt electrical current must have all wires and connections well-shielded.

  • Automotive-type wet cell batteries.
  • Electrical equipment operating on more than 12 volts with unshielded connection.
