Exhibit requirements for the WSSEF
Allowable Exhibit Size:
The maximum allowable exhibit dimensions are:
Depth (front to back)
76 cm. (30 in)
Width (side to side)
122 cm. (48 in)
Height (top to bottom)
274 cm. (108 in)
(Height includes the table)
Exhibits exceeding these dimensions will be disqualified at the
WSSEF and ISEF. Tables are furnished (76 cm. high), but tall
exhibits may be placed on the floor as desired.
Entrant to Furnish:
The entrant is required to furnish all materials needed to setup
and show his or her exhibit (e.g., 9 foot long UL approved
extension cord, tape, markers).
Project sounds, lights, odors, or any other display items must
not be distracting to other participants. WSSEF will
furnish electricity for all projects. Any surge protection is
the responsibility of the student. (See further rules under the
“Electrical Regulations” further down on the page.
Name of Students and Schools on Exhibits:
student’s name and/or school name appears on the exhibit, in the
journal, or in the abstract, it must be hidden from view
(erased, taped over, or otherwise covered for the duration of
Removal of Exhibits:
Exhibits must remain in place until 5:00 PM Saturday for posting
of awards and public viewing. All exhibits must be removed
Saturday starting at 5:00pm. Abandoned exhibits will be
The Scientific Review Committee, and/or the Display and Safety
Committee reserve the right to remove any project for safety
reasons or to protect the integrity of the WSSEF and its rules
at Project or in Booth

6. Plant materials (living, dead, or preserved) that are in
their raw, unprocessed, or non- manufactured state (Exception:
manufactured construction materials used in building the project
7. All chemicals including water (Exceptions: water integral to
an enclosed apparatus or water supplied by the Display and
8. All hazardous substances or devices [for example, poisons,
drugs, firearms, weapons, ammunition, and reloading devices.
Lasers are allowed with the restrictions indicated in item 5 in
the rules section below entitled “Allowed at Project or in Booth
BUT with the Restrictions Indicated.”
9. Dry ice or other sublimating solids
10. Sharp items (for example, syringes, needles, pipettes,
11. Flames or highly flammable materials
Batteries with open-top cells
13. Photographs or other visual presentations depicting
vertebrate animals in surgical techniques,
dissections,necropsies, or other lab procedures
14. Active Internet or e-mail connections as part of displaying
or operating the project.
15. Prior years’ written material or visual depictions on the
vertical display board. [Exception: the project title displayed
in the Finalist’s booth may mention years or which year the
project is (for example, “Year Two of an Ongoing Study”)].
Continuation projects must have the Continuation Project Form
(7) vertically displayed.
16. Glass or glass objects unless deemed by the Display and
Safety Committee to be an integral and necessary part of the
project (Exception: glass that is an integral part of a
commercial product such as a computer screen).
17. Any apparatus deemed unsafe by the Scientific Review
Committee, the Display and Safety Committee, or Society for
Science & the Public (for example, large vacuum tubes or
dangerous ray-generating devices, empty tanks that previously
contained combustible liquids or gases, pressurized tanks, etc.)
Project or in Booth BUT with the Restrictions Indicated
1. Soil, sand, rock, and/or waste samples if permanently encased
in a slab of acrylic
2. Photographs and/or visual depictions if:
a. They are not deemed offensive or inappropriate by the
Scientific Review Committee or the Display and Safety Committee.
This includes, but is not limited to, visually offensive
photographs or visual depictions of invertebrate or vertebrate
animals, including humans. The decision by any one of the groups
mentioned above is final.
b. They have credit lines of origin (“Photograph taken by...”or
“Image taken from...”). (If all photographs being displayed were
taken by the Finalist or are from the same source, one credit
line prominently and vertically displayed is sufficient.)
c. They are from the Internet, magazines, newspapers, journals,
etc., and credit lines are attached. (If all photographs/images
are from the same source, one credit prominently and vertically
displayed is sufficient.)
d. They are photographs or visual depictions of the Finalist.
e. They are photographs of human subjects for which signed
consent forms are at the project or in the booth. (Human
Subjects Form 4 or equivalent photograph release signed by the
human subject must be included in the paperwork.)
4. Any apparatus with unshielded belts, pulleys, chains, or
moving parts with tension or pinch points if for display only
and not operated
5. Class II lasers if:
a. The output energy is <1 mW and is operated only by the
b. Operated only during the Display and Safety inspection and
c. Labeled with a sign reading “Laser Radiation: Do Not Look
d. Enclosed in protective housing that prevents physical and
visual access to beam
e. Disconnected when not operating
Note: Class II lasers are found in laser pointers and in aiming
and range-finding devices. They pose a risk if the beam is
directly viewed over a long period of time.
6. Class III and IV lasers if for display only and not operated
(See the description of Class III and Class IV lasers
in the Radiation section of the Hazardous Chemicals, Activities,
or Devices chapter of the International Rules for Pre-college
7. Any apparatus producing temperatures that will cause physical
burns if adequately insulated
1. Finalists requiring 120 Volt A.C. electrical circuits must
provide a UL-listed 3-wire extension cord which is appropriate
for the load and equipment.
2. Electrical power supplied to projects and, therefore, the
maximums allowed for projects is 120 volt, AC, single phase, 60
cycle. Maximum circuit amperage/wattage available is determined
by the electrical circuit capacities of the exhibit hall and may
be adjusted on-site by the Display and Safety Committee.
3. All electrical work must conform to the National Electrical
Code or exhibit hall regulations.
4. All electrical connectors, wiring, switches, extension cords,
fuses, etc. must be UL-listed and must be appropriate for the
load and equipment. Connections must be soldered or made with
Wiring, switches, and metal parts must have adequate insulation
and over-current safety devices (such as fuses) and must be
inaccessible to anyone other than the Finalist. Exposed
electrical equipment or metal that possibly may be energized
must be shielded with a nonconducting material or with a
grounded metal box to prevent accidental contact.
5. Wiring not part of a commercially available UL-listed
appliance or piece of equipment must have a clearly visible fuse
or circuit breaker on the supply side of the power source and
prior to any project equipment.
6. There must be an accessible, clearly visible on/off switch or
other means of disconnect from the 120 Volt power source.
7. Any lighting that generates considerable and excessive
amounts of heat (high-intensity lamps, halogen lights, etc.)
must be turned off when the student is not present at the
project. These types of lightning should be turned off unless
presenting the project to judges.
