We caught up with both of them after the protests to see how the day went.
Perri said a walkout organizer walked into the classroom to announce that the protest was beginning. "Everyone then got up, and then I proceeded to do my homework," he said. He was tempted to walk out "but I also wanted to stick to my guns, literally but also metaphorically, and just believe in what I believe."
Gordon, who organized Arapahoe's walkout, said the crowd there was in the hundreds. "As we walked out at first, it wasn't very many kids. About two minutes later I looked back up and I just saw a wave of people walking out of the building."
Still the crowd was a bit smaller than Gordon had hoped. "I could never be disappointed in what happened ... because it was one of the most inspiring shows of student activism I've ever seen," he said.
For better or worse, Perri said, he was struck by how quickly the student protests have gained momentum. "I learned how just a slight movement that someone can start can just spread like a forest fire,'' he said. "Once it takes root it's hard to get rid of that."
Gordon said he hopes adults take a message from the walkouts. "I'm hoping they see that we've been brought up in a world that kind of got pretty messed up over the last 20 years and that we're not going to just sit there and pout about it. We're going to stand up and speak out and start to fix it."
