USC Shoah Foundation records the testimonies of genocide survivors so the world will never forget their stories. Eighth-grade student Andrea Chang decided to do something similar for her community: document the stories of the elderly. As part of the third-annual IWitness Video Challenge, Andrea created a video demonstrating her project, in which she spoke to the elderly and shared their stories. Her video, “Tell Me Your Story,” took third place in the national competition, landing her a $500 scholarship.
