Gun violence at schools has been a hot button issue for years, but was reignited following this past February's school shooting in Parkland, Florida.
That's why Friday, thousands of students across the U.S. and mid-Michigan are walking out of class to demand lawmakers take action against gun violence.
Some students from Okemos High School, Dewitt High School, St. Johns High School and Wexford Academy will be participating in the walkouts.
These are coinciding with the 19th anniversary of the Columbine High School shooting.
That event left 13 people dead and more than 20 hurt in Littleton, Colorado when two students shot at their fellow classmates before turning the gun on themselves.
Organizers say more than 2,600 demonstrations are planned from Maine to Hawaii on Friday.
Many students say they'll wear orange and leave class at 10 A.M. to take a moment of silence for victims of Columbine and other shootings.
FOX 47 has heard from some schools saying that if a student participates that it will be an unexcused absence.
