Please Note: No class projects are accepted!

Participant/Project Registration

Participant registration MUST be submitted and CERTIFIED using the WEBSITE System on or before Friday, March 13, 2015. There will be NO on-site registration.


Each school (K-5, K-6, 6-8, 7-8, or High School) may submit as many inventions as they feel are competitive. We recommend a total of 12 inventions regardless of grade level. Each school is responsible for determining which inventions will be submitted.


Displays are limited to 24 inches deep (front to back), 36 inches wide (side to side at the widest extension of the side panels), and 9 feet high (top of the project to the floor, including the table, which is approx. 30 inches high). Inventors are encouraged to use heavy gauge material that will not fatigue (Displays constructed of thin cardboard tend to fold on themselves after being erected for several hours).

Each display MUST have an Inventor Notebook and a bibliography (a list of references and/or people consulted about the Invention). All entries (pages) in the Inventor Notebook (students are encouraged to follow the Lemelson Young Inventors Notebook Information) dealing directly with the Inventor Ideas and Drawings should contain both the Inventor Signature and Date along with a Witnesses Signature and Date.

All grades MUST have the Student Entry Form attached to the front of their display board.

A LYIC Check Sheet MUST be completed by the Fair Director, the Exhibitor(s) and the Parent(s) AND MUST be attached to Back Right Side Panel (display closed) of the Invention Display Board prior to WNRS&EF.

Please make sure that the student name and school is written on the on the inside cover of any notebooks.

All invention displays MUST to have a MODEL of the INVENTION. The model does not have to actually work or be a prototype; it should represent your invention idea. Use everyday materials from around your home or school. Please label your invention clearly and have your Invention Name on the Model. All Models must sit directly in front of the Display Board or be attached to the front of the Display Table.

Please Note: No human or vertebrate animal may be used in development or proofing tests of invention concepts or designs if there is any potential for injury of, pain, or stress.
