The New York Hall of Science is New York City’s hands-on science and technology center, with more than 400 interactive exhibits exploring physics, chemistry, and biology. The Hall also creates and presents demonstrations and programs for students and families, and is the leading provider of professional development in the physical sciences for New York City teachers. The Hall is located in Queens, the most ethnically diverse county in the country. Therefore, a centerpiece of the Hall’s efforts to build and support diversity is its Science Career Ladder (SCL): a program that engages young people in a hierarchy of paid experiences in the museum, designed to cultivate interest in science and science education as possible career paths.
