Open seasonally, the Discovery Barn is designed for families and school groups. Themed around the schooner L. A. DUNTON, scientific principles behind a ship’s sail power, stability, hull shape, and simple machines that run the vessel are explored. Here, parents and children can explore the exhibit "Force in Motion at Sea" through computer displays and other hands-on activities that provide interactive scientific learning experiences. Children learn the physics of simple machines in an entertaining and fun manner. Using block and tackle they lift themselves up with pulley power. They explore using sails for speed; steering a vessel; keeping the vessel stable at sea; loading fish; understanding the motions of pitch, roll, and yaw; and reading the flags—all done in the context of how the Dunton sails, moves, floats, and carries out its work at sea.
