The Imagination Factory Children’s Museum in Iron Mountain had its grand opening this weekend. After two years of work, volunteers and others have converted space in Iron Mountain’s former Central Middle School at 217 W. Hughitt St. into 25 interactive exhibits in rooms with themes on health, industry, the environment and more. In the first photo, 3-year-old Ford Gendreau and sister Amelia, 10, play Saturday on the virtual mat in the health room. In the second photo, 6-year-old Colton Huotari, mother Jenny Baker-Huotari and Alex Huotari, 10, dig a lake in the virtual sandbox in the environment room. (Brian Christensen/Daily News photos)
