Many parents worry about their kid's cellphone usage, but few have a clear view of what they're actually doing on their phones every day. A new documentary explores how phones impact the daily lives of teens in one Los Angeles high school over the course of a year. Director Lauren Greenfield joins us to discuss"Social Studies," a new FX series that is available to stream now on Hulu. The film team has also put together an Educational Curriculum and Parents Guide to complement the documentary.
