Our story picks back up with the question of how non-cognitive skills can be taught to older kids who have gone much longer without learning things like self-control, conscientiousness and resilience. Ira returns to the story of Kewauna, the Chicago teenager, who talks about the dramatic ways in which she changed her life.

In an effort to understand the physical and emotional changes middle school kids experience, Ira speaks with reporter Linda Perlstein, who wrote a book called Not Much Just Chillin' about a year she spent following five middle schoolers.

As adults battle over how climate change should be taught in school, we try an experiment. We ask Dr Roberta Johnson, the Executive Director of the National Earth Science Teachers Association, who helps develop curricula on climate change, to present the best evidence there is to a high school skeptic, a freshman named Erin Gustafson.

Jyllian Gunther visits The Brooklyn Free School, where there are no courses, no tests and no homework, and where the kids decide everything about how the school is run, including discipline. Jyllian is a filmmaker, working on a documentary called Growing Small.
