While we do not have a formal mentorship program at MSSF, we know that students and teachers sometimes connect with mentors. A successful mentor finds a balance between guiding students and allowing them to grapple with the challenges they encounter in their projects. This is meant to be a starting point for mentors to find guidance on coaching students, but you can always reach out to the Science Fair team at


  • January 15 – Student Registration
  • February 2 – Research Plans due for projects involving human subjects
  • March 1 – Abstracts due for all projects
  • March 23 – Maine State Science Fair @ UMaine


The MSSF Team would like to be sure that teachers, students, and judges are aware of our COVID policy. Given that we are expecting people from many parts of the state, the Jackson Laboratory and Maine Mathematics & Science Alliance will retain our masking requirements and spectator policy:
  • The event is closed to spectators beyond chaperones accompanying bussed students and parents who are driving their teens to the event because their school does not provide a bus.
  • Everyone in attendance will remain masked for the duration of the event while in the Field House, including any aforementioned parents or chaperones.
  • Any student who meets the CDC Guidelines for Quarantine or Isolation must participate virtually.
  • Students can also switch to virtual participation for any reason, but they cannot switch from virtual to in-person.
  • On a related note, Colby College does not allow any food or drinks, except for water, in the Field House. We will send students home with boxed lunches at noon.
Please contact the MSSF team if a student is switching to virtual participation. If you have any questions about these policies, please do not contact the venue. The MSSF Team is happy to answer your questions.


The following Rules and Guidelines are excerpted from the International Rules and Guidelines for Science Fairs, Society for Science & the Public.

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
  • protect the health and welfare of the vertebrate animal subject
  • ensure adherence to federal regulations
  • ensure use of safe laboratory practices
  • protect the environment
  • ensure eligibility for competition in the Intel International Science and Engineering Fair

Ethics Statement

Scientific fraud and misconduct are not condoned at any level of research or competition. This includes plagiarism, forgery, use or presentation of the researcher’s work as one’s own, and fabrication of data. Fraudulent projects will fail to qualify for competition. The Maine State Science Fair reserves the right to revoke recognition of a project subsequently found to have been fraudulent.


  • A student must be in grades 9–12 or equivalent and not have reached age 20 on or before May 1 immediately following the fair.
  • Each student may enter only one project. That project may include no more than 12 months of continuous research and may not include research performed before January of the previous calendar year.
  • Team projects may have up to three members. Teams may not substitute members in a given research year.
  • A research project may be apart of a larger study performed by professional scientists, but the project presented by the student must be only their own portion of the complete study.

All Projects

  • All projects must adhere to the ethics statement above.
  • All projects must adhere to local, state and U.S. Federal laws, regulations and permitting conditions.
  • The use of non-animal research methods and the use of alternatives to animal research are strongly encouraged and must be explored before conducting a vertebrate animal project.
  • Introduction or disposal of non-native species, pathogens, toxic chemicals or foreign substances into the environment is prohibited.
  • Exhibits must adhere to MSSF display and safety requirements.

Approval and Documentation

  • Projects involving human participants, vertebrate animals, and potentially hazardous biological agents and subject to prior review and approval by the Maine State Science Fair Institutional Review Board (IRB) or Scientific Review Committee (SRC).
  • Each project must name an Adult Sponsor (typically a classroom teacher or another adult research mentor), who must sign off on the project.
  • A Qualified Scientist is required for all studies involving BioSafety Level-2 (BSL-2), potentially infectious or hazardous biological agents, and DEA- controlled substances, and is also required for many human participant studies and many vertebrate animal studies.
  • After initial IRB/SRC approval (if required), any proposed changes in Research Plan must be re-approved before laboratory experimentation/data collection resumes.
  • Projects which are continuations of a previous year’s work and which require IRB/SRC approval must undergo the review process with the current year proposal prior to experimentation/data collection for the current year.
  • Any continuing project must document that the additional research is new and different.
  • If work was conducted in a Regulated Research Institution (such as a university or laboratory), industrial setting or any worksite other than home, school or field, at any time during the current MSSF project year, then a representative of the Regulated Research Institution must also sign off on the project.
  • After experimentation, each student or team must submit a one-page abstract, which summarizes the current year’s work. The abstract must describe research conducted by the student, not by the supervising adult(s).
  • A data notebook is required of every project.

Topic-Specific Rules and Guidelines

MSSF Display and Safety Rules

  • Only freestanding tabletop displays are allowed. MSSF will not provide tripods or other poster holders at the fair venue.
  • Size Limitations – 30 in (76 cm) deep, 48 in (122 cm) wide, 78 in (198 cm) high from tabletop.
  • Equipment and electricity at the table- No equipment other than what is an integral part of home-built apparatus will be allowed in the display during judging. No electric power will be available during judging. Laptops may be used to demonstrate software local to the machine.
  • The participant’s name, address, town, phone number, e-mail, website, and school name should not appear on the project, with the exception of the abstract. The participant’s name may be on the back of the poster board.
  • New in 2023: Acknowledgements on the project display are no longer prohibited; in alignment with the MSSF ethics statement, students may recognize those that have supported their work in a section on the display.

Not Allowed At Project

  • Living organisms including plants, animals, and microbes
  • Taxidermy specimens or parts
  • Preserved vertebrate or invertebrate animals
  • Human or animal food
  • Human/animal parts or body fluids (for example, blood, urine)
  • Plant materials (living, dead, or preserved) which are in their raw, unprocessed, or non-manufactured state
  • Laboratory/household chemicals including water (Exceptions: water integral to an enclosed apparatus; crystals grown by you, displayed in a case, and removed after final judging)
  • Poisons, drugs, controlled substances, hazardous substances or devices (for example, firearms, weapons, ammunition, reloading devices)
  • Dry ice or other sublimating solids
  • Sharp items (for example, syringes, needles, pipettes, or knives)
  • Flames or highly flammable materials
  • Batteries with open-top cells
  • Awards, medals, business cards, flags, endorsements, and/or acknowledgements (graphic or written) unless the item(s) are an integral part of the project
