The Downfall of the Diorama

Abstract

Abstract Over the course of the twentieth century, millions of American children conducted their first science experiments by participating in science fairs. In tracing the development of a new visual medium of the 20th century – the science fair display – this paper captures the unruliness of scientific representation from a child’s eye view. The essay traces this phenomenon against the backdrop of broader debates regarding the role scientifically inclined youth would play in shaping the nation’s future. Science fairs also raise important philosophical questions regarding the epistemology of children’s experimentation. Over the course of fifty years, three-dimensional dioramas of the Progressive era were supplanted by postwar argument-driven text panels, capturing a distinct rupture in scientific representation. The essay argues that science fair displays provide an entry point for understanding how adolescents conceived of science on visual, material, social, and epistemological terms.
