All grades may enter an exhibit as a Team.  Team exhibits are allowed a maximum of 3 students.  Team projects require 1 printed entry form for each student signed by the student and their respective parent/guardian.

Please note that if a student submits a project as part of a Team, they may not enter another exhibit as an Individual.

This file will include a copy of the completed Mastodon Fair Science entry form, the Exhibit ID labels and further instructions.  DO NOT print out the Exhibit ID labels until you receive an email notification letting you know the labels are ready to print, approximately one week after Registration closes.

Safety Forms

Grades 9-12 must have submitted completed ISEF Safety forms by Nov. 30, 2017 in order to be eligible for ISEF competition.  Contact for information about late submittal of ISEF forms.

The following 3 ISEF safety forms are required at a minimum.

Form 1

Form 1A

Form 1B 

Please read Form 1 carefully to determine what additional ISEF forms may be needed depending on the research area.  Visit the ISEF “Rules Wizard” website and follow the directions to determine what additional forms may be required.  Feel free to contact the Mastodon Fair Science Director at for further assistance.

If you have not already submitted your completed ISEF Safety Forms by Nov. 30, then you may use the Mastodon Fair Safety Form instead for certain types of exhibits only but will not be eligible for ISEF competition.  The Mastodon Fair Science Safety Form includes a list of exhibit types NOT covered by the form.  If your exhibit type appears on that list, you will need to submit the appropriate ISEF forms but will not be eligible for the ISEF competition because they were submitted after the Nov. 30 deadline.  Contact for information about late submittal of ISEF forms.
