Science and Engineering Fair

The Virtual 2021 North Museum Science and Engineering Fair (NMSEF) serves as Lancaster County’s only free, ISEF-affiliated science fair. Our fair is open to Lancaster County 7th – 12th grade students in public, private, or home schools. The Fair this year will be held online. If you missed the kick-off meeting held on September 17th, please contact Dave Musser, LEAD STEM Education Facilitator (717-358-4371) for a copy of the recorded Zoom meeting.
