Writing an abstract
The abstract is a short description of what your project is, why you did it, what your results look like and the analysis of those results. The latter should be the bulk of the abstract.
The abstract is written AFTER the project is completed. It is not written before or during experimentation although you can make notes that would be used in an abstract.
The ISEF abstract is limited to 250 words. That is usually a few paragraphs. This is the same for the Mercer Science and Engineering Fair although we use our own abstract form. Do not use the ISEF abstract form. We are also less strict on the word limit but remember that the abstract is going to be the way for a judge to get an idea of what your project entails so make it concise.
The abstract is printed and placed in front of the project. It can be on the project board but we recommend placing it on the table to free up space on the board for other parts of the student's presentation.
Below are some sample abstracts used by award winning projects at the fair.
