Dwayne Rehfeld Award
The Dwayne Rehfeld Award for Excellence in Service and Science is given to a high school junior or senior participating in the fair. Dr. Rehfeld, a professor of chemistry at Northern for 23 years, started the regional fair in 1983. He encouraged the pursuit of excellence in scientific inquiry and associated critical thinking skills, as well as Christian values, respect for others, integrity, volunteerism, participation in extracurricular activities, and providing positive peer role models. The award includes cash for teaching materials for the winner's high school's science classroom; a cash award to the winning student; and a cash donation to the Aberdeen Salvation Army in the student's name.
