This CS4NE episode highlights unplugged computer science activities that build problem-solving, creativity, communication, and teamwork without using computers. Kimberly shares a cup-stacking challenge using cups, string, and rubber bands, where students must collaborate under increasing constraints, and an index-card challenge where students figure out how to cut a small card so it can fit over someone’s head. The hosts connect both activities to core computer science ideas, including multiple solutions, iteration, debugging, collaboration, and the broader value of computational thinking beyond simply writing code.
