The Tuesday walkouts are just the beginning of several planned national school walkouts.
And on Monday, dozens of teens staged a “lie-in” outside the White House.
On March 14, students across the US will participate in a national school walkout, planned by the Women's March organizers.
And, on March 24 students and supporters will march on Washington, DC, to demand gun control in the March For Our Lives. This protest is being planned by student organizers from Stoneman Douglas.
“There cannot be two sides to doing everything in our power to ensure the lives and futures of children who are at risk of dying when they should be learning, playing, and growing,” the March For Our Lives organizers said in their mission statement.
Another national school walkout is planned for April 20, the anniversary of the shooting at Columbine High School in 1999.
Additionally, many high schools are planning their own protests and walkouts this week.
“There may be different dates but this is one movement!” the organizers of the April 20 protest said.
