Seven youngsters from the Dunham Children's Learning Center toured a Penn College carpentry lab Thursday morning, learning about the literal tools of the trade and assembling mementos to take back to their classroom for paintbrush personalization. Marc E. Bridgens, dean of construction and design technologies, acquainted his guests with a variety of topics – including rafters, drywall, forklifts, staircases and (always) safety – and helped them build toolboxes as a lasting reminder of their visit.
