TRACTOR PROJECT In each class the exhibit shall be an educational exhibit which will show or illustrate what the member has learned. Include an explanation telling:( a) how the exhibit was made or what was done in the project;( b) operating instructions( if appropriate); and( c) what the member learned by the doing the project.

TECHNOLOGY In some cases, the exhibit may be a poster or a three-dimensional display. Individual exhibits are limited in size to 30” wide, 24” deep( front to back), and 36” high. Club exhibits are limited in size to 60” wide, 24” deep and 36” high. Posters must not exceed 22” x 28”.

AEROSPACE PROJECT Each exhibit piece must be labeled with the member’ s name, county and class number. If more than one article is contained in the exhibit each article must be labeled with the member’ s name, county and class number. This may be done with masking tape, attaching an index card, or writing directly on the back with a marker. All the articles that comprise the exhibit must be attached to each other. The one exception to this is the Rocketry Engineering Journal, which must be included with the Rocket display, but is not required to be attached to it.

Each exhibit must include the current year’ s edition of the appropriate Project Description for the exhibit form filled out neatly and securely attached to the exhibit. 4-H Project Description sheets are posted at http:// oregon. 4h. oregonstate. edu / fair-exhibit-and-contest-materials. Be sure to use the newest version of the Project Descriptions for each technology exhibit. Exhibitors should answer the description page carefully and in full sentences. This is the exhibitor’ s opportunity to tell the judge about their project.
