Washington, D.C. ? The Brown v. Board of Education National Historic Site has activities planned to commemorate Martin Luther King Jr. Day.

Children and family members can create protest signs inspired by slogans of the civil rights movement. The park will air two films about King: “Citizen King” and “Roads to Memphis.”

There also will be scavenger hunts and a trivia game focused on King. The trivia participants will take home a souvenir, and a special prize will be awarded to the top-scoring team in each game.

The Topeka park tells the story of the U.S. Supreme Court ruling that toppled segregated education.

Admission to all national parks is free through Monday. Brown park site superintendent David Smith calls it “a great excuse to go to a park.”
