The National Geographic Society, founded in 1888 for the increase and diffusion of geographic knowledge, is the world's largest nonprofit scientific and educational organization. Since its earliest days, the Society has used sophisticated communication technologies, from color photography to holography, to convey geographic knowledge to a world-wide membership. The Education Products Division supports the Society's mission by developing innovative educational programs ranging from traditional print materials to multimedia programs including CD-ROMs, videodiscs, and software.

We hope you enjoy the special features written by the National Geographic Society especially for Science Interactions Course 3.
