Philadelphia schools, from elementary schools to universities, are participating in the National School Walkout to protest gun violence after the mass shooting at Marjory Stoneman Douglas High School in Parkland, Fla.. The walkout is scheduled for 10 a.m. and will last 17 minutes, commemorating the 17 victims who died in the shooting.

Some local schools and parents shared information about their participation in the walkout on social media. Other schools sent out instructions to their students advising them on how to make the event safer.
