Project Exploration is a Chicago-based nonprofit science education and youth development organization launched in 1999 to address inequities in access to high-quality STEM (science, technology, engineering, math) opportunities in out-of-school time. With equity at our core, we serve youth from communities historically underrepresented in STEM fields and recruit students who are curious and interested in science but face systemic challenges to accessing high-quality programs, such as academic prerequisites or program fees. Our programs deeply engage students in authentic STEM experiences, alongside mentors and STEM professionals who serve as role models. Through these programs and relationships, youth develop critical social and emotional skills, such as self-confidence, science identity, collaboration, communication, and leadership abilities.
