Iridescent’s mission is to inspire underserved communities to develop a deeper understanding of cutting-edge science and be motivated to pursue a career in STEM. Our approach is to provide rich, immersive, self-directed, inquiry-based experiences for families. These learning experiences are designed by student engineers. Student engineers lead five-week courses for the families at the school sites in the evenings. Topics illustrate the real-world applications of basic science concepts and range from the Cardiovascular Mechanics to Bird-flight Aerodynamics. Since July 2006, Iridescent has trained ~185 engineers who have conducted 120 courses reaching ~ 4000 underserved children and their parents.
