Harsco Science Center Exhibits
Color and Light
Color and Light art, science and technology are explored in The Galleries of Color and Light. They include the Gallery of Light and Color, and Light at Work, which reveals the ways that light is used in science and industry. Its icon exhibit is a large-scale, interactive, walk-through Kaleidoscope that blends science and art through color, light, mirrors and dazzling rainbow holograms.

The Gallery of Light and Color invites visitors to discover the basic science of light as they carry out experiments that answer questions such as What is light? Where does it come from? How does it behave? Why is the sky blue? Visitors create and experiment with waves, shadows and optics, rods and beams of light which appear and disappear. They create pictures with polarized light and assemble telescopes and microscopes.

Color Exhibits show why red, blue and yellow are the primary colors for pigments but red, green and blue light make up all the colors on a television set. Visitors learn about additive and subtractive color mixing, and see how colors change and things appear and disappear when viewed through different colored windows.

Light At Work demonstrates how visible light is only one segment of the electromagnetic spectrum, which spans gamma and x-rays, ultraviolet and visible light, infrared radiation, microwaves, and radio waves. This is one of the most fundamental concepts in science, and is an important part of The Galleries of Light and Color. Light At Work reveals the practical applications of visible and invisible light in areas as diverse as medicine, communications, entertainment and computing.
