COSI - Franklin County Historical Society

COSI is a nationally esteemed science center that has delighted Central Ohio with all things science for 55 years, inspiring interest in science, technology, engineering, and math (STEM) topics and delivering our experiential, "hands-on fun" brand of learning. As a trusted educational resource for families, schools, and community partners, COSI is an essential element of our community, engaging more than one million people annually through onsite, offsite, and online experiences.

COSI - like science - is for everybody: all age, backgrounds and abilities. With this guiding belief, we serve as a pillar of learning and a cultural cornerstone committed to serving all members of our diverse community. Across our 320,000 square foot facility, we bring science to life through 300+ interactive experiences, nine galleries featuring world class traveling and permanent exhibitions, explosive live shows, our little kidspace® exhibit for learners birth through first grade, and a Planetarium. Outside our building, our award-winning educational outreach programs reach over 300,000 students annually in schools and community organizations across Ohio and neighboring states.

Whether a trusted educational resource, a cherished local tradition, or a critical player in downtown revitalization, COSI is an integral part of our community. In pursuit of our vision to engage, inspire, and transform lives, we serve as a beacon of accessible STEM learning for all. By providing families, teachers, and students with the tools and knowledge to pursue lifelong learning, COSI fosters and supports a STEM-literate community prepared to compete in the digital economy and overcome the challenges of the 21st century.

Through our commitment to being inclusive and accessible, more than 36 million memory-making engagements have been created by COSI through our on-site and outreach experiences since our opening in 1964.
