On Saturday, September 14th, 2019, from 10:00 AM to 2:00 PM, join our annual ID Day at the Field Museum—free for Illinois residents. Bring in remnants of the natural world—including clean, dry bones, fossils, rocks, seashells, and photographs of the natural world—to be identified by the Field’s scientists. This year, ID Day will also include a poster-making station for the upcoming global Climate Strike. You provide the ideas and we’ll provide the supplies.
