Welcome to the homepage of the Mid-Columbia Science Fair Association (MCSF Association). The MCSF Association is a non-profit 501(c)3 organization which exists to organize and hold the Mid-Columbia Regional Science and Engineering Fair. We are the oldest science fair in the state of Washington and operate with 100% volunteer time and effort. The MCSF Association works with teachers and students of the Mid-Columbia area of Washington state, with the students conducting their chosen research project. Projects entered into the regional fair are judged by professionals in applicable fields and are publicly displayed.
