About our fair

The Mercer Science and Engineering Fair (MSEF) has been held for more than 50 years in  Mercer County, NJ. It is open to all students who attend school in Mercer County in grades 4 through 12. Students in grades 9 through 12 in near by New Jersey counties may also participate if their county is not covered by another ISEF affiliated fair. The grand prize winner for the Senior Division receives an all expense paid trip to the Intel International Science and Engineering Fair (ISEF). There is no charge to participate in the fair.

Why should a student participate in MSEF? First of all, it is fun. Students can also win awards and scholarships. Scholarships to leading colleges and universities are awarded at ISEF.

Students get a chance to explore topics in all areas of science, engineering, and mathematics. They get hands-on experience in topics that interest them and students develop expertise in the scientific method. Presentation skills are also developed increasing a students confidence and poise.
