Paul Salopek is on a seven year trek, literally walking around the world — and he's posting photos, videos and comments about his journey online. Guest host Celeste Headless speaks with Salopek and Pulitzer Center education advisor Homa Tavangar, about the different things kids can learn by seeing the world through Paul's eyes.
