The Paradigm Challenge is an annual competition developed by Project Paradigm and the American Red Cross to inspire youth to use science, technology, engineering, and mathematics (STEM) skills—as well as kindness, creativity, and collaboration—to make a difference. It aims to generate new ideas to reduce waste in homes, schools, communities, and around the world. Youth are invited to submit entries, including posters, videos, inventions, public messages, community events, websites, mobile apps, or anything else that will help reduce waste.
