The Ocean Explorium uses the Science on a Sphere as a point of departure for learning about the planet in all its variety. This is a particularly powerful mechanism for a community filled with citizens who have had little chance to travel outside their immediate region. The combination of high-tech information streams, living and non-living interactive exhibits, art and craft activities, and structured learning programs, represent a powerful prototype for informal STEM (Science, Technology, Engineering and Mathematics) learning. Through its various programs, the Ocean Explorium has helped families, students, and teachers explore new worlds.
