Middle school students in London also recognized First Responders during a 9/11 remembrance ceremony.
A 9/11 commemoration program had all eyes and ears of students at North Laurel Middle School.
These 6th graders were infants on September 11th, 2001.
"It dawned on me this year that these children know absolutely nothing about it, so we have had to start from nothing talking to them about it," said Peggy Sasser, North Laurel Middle School teacher.
Local First Responders talked about the events of that day and answered questions from students.
To the 6th graders, 9/11 is just a history lesson. To the First Responders, it is a day they will never forget.
"That big thing of black smoke rolling across the sky. You know what I'm talking about? Everybody knows. That's the first thing I saw," said Mike Holliday, London Police Department Officer.
The students took a moment of silence for the nearly 3,000 people who died.
Teachers say it is important students understand the effects of 9/11.
"I want to be able to give that to the children. A sense of how it actually felt on that day," said Sasser.
The program started seven years ago, and teachers say they plan to have one every year.
Teachers say the students continued to learn about the events of 9/11 throughout the school day.
