For Educators

Educator and Student Activities

A consortium of science centers, led by the New York Hall of Science and including COSI launched learnXdesign.org. The website offers more than 30 hands-on activities for use by educators in a variety of out-of-school settings, including after-school programs, libraries, and youth clubs. Find out more at: learnXdesign.org

COSI’s online activities are an extension of the great fun and educational experiences you can find in our building and with our programs. Use them in your classroom!
