There are a number of ways Americans observe Patriot Day and remember those lost in the September 11th attacks.
For many UNO students, it's been about giving back to the community.
Several teams of students went out in the area doing community service.
Some near 68th and Spring, planted flags at the athletic fields.
They were marking holes for maintenance crews to fill in preparation for an upcoming cross country race.
“I think everyone can understand the importance of helping out on this day, because we all remember what's happening, because it's “Remembrance Day” so we're just kind of commemorating and giving our time so we can help out our community,” says Caitlin Osborn, one UNO volunteer.
Student volunteers also did different projects at Lothrop Elementary School, and Habitat for Humanity in Omaha.
