The mantra: "turn off the screen before you are mean."
It's part of a bullying-awareness month at this school.
"We decided to do this because we feel like it's an issue at Desert Hills - not as much physical but verbally through cyber-bullying," said student Kendyl Holle.
"I feel like it's a problem everywhere though - not just at our school, but we really want to end bullying," said student Tristar Davis.
Upcoming themes include - stop bullying and jump into spring - and keep class and don't harass.
