Ok. You have finished or almost finished your project and now you need to put it into a form that you can present all your work. The presentation is part of the online application process so make sure you have started an application. Of course, this also assumes you have an account on the website.
Here we assume you have an application started and need to provide the presentation details. This includes the hypothesis/purpose, a research plan, an abstract and additional materials the highlight your project. The following section deals with those details.
Note, the forms for the International Science and Engineering Fair (ISEF) are only needed for the Junior and Senior Divisions of the annual Mercer Science and Engineering Fair.
