Interpretive Demonstrations and Illustrated Programs are prepared, formal programs that involve the planned integration of spoken narration with media or demonstration. An Interpretive Demonstration may be performed by the interpreter, the visitor, or both, and can take a variety of forms such as living history, cultural and craft demonstrations, the use of historic weapons, nature experiments, etc. The successful Illustrated Program depends on the interpretive integration of illustrative media with narration. Illustrations can include either two- or three-dimensional objects, slides, photographs, maps, artifacts, or performance arts such as music or dance.
Unlike the interpretive talk in which the narrative can primarily stand alone, the narration of a demonstration or illustrated program is integrated and interdependent with the media or demonstration to present enhanced opportunities for intellectual and emotional connections to resource meanings/significance.
