The walkouts are expected at 10 a.m. on the anniversary of the Columbine shooting, which left 12 students and one teacher dead, in addition to the two gunmen.
"We've heard "this is the world's biggest mass shooting" or "the country's biggest mass shooting" I've heard that headline so many times in my life, and I'm only 18", Bellmont High School student Morgan Murphy said.
Students also used the rally to focus on getting people registered to vote, because they said that is where the real change begins.
Pomp said students at her school may face disciplinary action for the walkout, but consider the march an act of civil disobedience.
High school students from across Arizona occupied the House and Senate lobbies and the governor's office at the state Capitol Friday in the latest protest against gun violence.

On April 20, 199, about 19 years ago, the shooting massacre at Columbine High School stunned the nation.
"I do think that at a minimum we should be enforcing the will of the people", said Senator Aaron Ford, D- Nevada.

"Our students are passionate about school and safety and we supported them in their efforts [Friday]".
"She didn't want me to make me feel sad on my birthday, so she didn't tell me that day".
"It's not fair", she said.
It began with a change.org petition that she started in the wake of the Marjory Stoneman Douglas High School shooting in February.
Organizers also provided letters addressed to state representatives available for people to sign at the conclusion of the walkout and encouraged their peers to write pieces of legislation that they would like to see enacted.
