Chicago beaches are now officially closed, the weather is expected to get cooler later this week and almost 400,000 Chicago kids are back in school today. It’s the unofficial end of summer. We check in with the head of Chicago Public Schools Forrest Claypool for his thoughts on the upcoming school year and what students and parents should expect. We also hear from the Chicago Teachers Union whose members head into the new school term without a contract. Chicago’s DuSable Museum of African American History has a new leader. Her name is Perri Irmer and she tells us about her plans for the south side cultural institution. And we cap off the show with a look at the film On Beauty, a former fashion photographer’s mission to redefine and challenge our notions of what it means to be beautiful. We’ll talk with the director of the film, which is part of a film festival called Reelabilities. We’re joined by two of the festival’s organizers.
