Mastodon Fair does not restrict the categories or subjects chosen by its science entrants. However, additional forms may be required based on the specific area of experimentation.

Please use great care in selecting the proper category. The category you select on the registration/entry form is the category in which the project will be judged. Changes in category will not be permitted after submission of the registration/entry form.

Mastodon Fair / ISEF Categories and Subcategories

The categories have been established with the goal of better aligning judges and student projects for the judging at the Intel ISEF.
