For your Category, refer to the Categories List (link) and choose the description that best matches your project.
You will be prompted to pay the $25 participation fee using the Science Fair Payment JotForm when you register. Please be prepared with a debit or credit card (or have your parent be prepared with one).
Be sure to double-check your school and grade level selection.
If you need to be stationed near an electrical outlet, please include that information on the form where it asks for special needs.

In addition to following the registration steps above, Senior Division students must submit ISEF Forms to our regional fair, the University of Utah Science and Engineering Fair, prior to participation in the Diocesan Fair.
Know the rules: Our fair follows the same rules as our regional fair, the University of Utah Science and Engineering Fair. Please read through their General Rules Page.
Know how you will be judged: Judges at the fair use a specific judging rubric to judge your project. Read through and understand the rubric to make sure that you are getting the most points that you can.
Choose an interesting topic: If you enjoy your project, you will be more motivated and you will naturally do a better job. Pick a topic that is interesting to you based on your interests. What do you like to do in your free time? What do you like read about? What will you watch a documentary on?
Do background research: Go online and read about your topic to see what is already known and what you could contribute to your field of interest. Reading about other scientists' research can give you ideas for how to conduct your experiment.
Don't be afraid to ask for help: Reach out to your teachers and members of your community who know about science and engineering to get help and advice on your project. Running your idea by another person can help you see where you might improve.
Dress for success: It's a Saturday and your day off from school, but a professional presentation will help your judges to see you as a serious young scientist. Wear your school uniform to look your best on the day of the fair.
Practice your presentation: Plan your presentation before the fair, and practice your delivery. Think about what questions judges might ask you and get ready with answers.
