Many Americans can pinpoint exactly where they were when the twin towers collapsed, but children in elementary school are too young to remember.
"They've told us that many people were killed," said Haeley Barr.
Barr has learned what she knows about 9/11 from her teachers at Dresden Elementary.
"These children were not alive, and I think they're relying on us to make sure that it's something that doesn't get forgotten," said Elaine Ross.
Dickie Barrick said it's strange to see the attacks in textbooks, but those pages can paint pictures in these childrens' minds.
"We just got done reading a book about the man who had walked between the towers," said Barrick. "The towers that he walked between don't exist anymore."
For Reily Jacobs-Bell, the stories hit close to home. Reily said her mother was boarding a plane that morning, and she might not have been born if it had been one of the flights that crashed.
"I feel bad for those kids that lost their parents," said Jacobs-Bell. "I know that it would be the worst thing that ever happened to me."
These kids may not remember 9/11, but they do remember our troops serving overseas. They're putting together care packages to show their appreciation.
"I think it's important at this age for them to learn that they really need to think about others in the world instead of just themselves," said Barrick.
"We want to make sure that they don't get hurt, so we're trying to help them with needs," said Shawn Adams.
Feeling protected by our service men and women, police officers and firefighters helps keep kids at ease during discussions about terrorism.
"We don't want it to be something scary," said Ross. "We want them to know that we've made it through it, and it made us a stronger nation."
Much like Pearl Harbor and the JFK assassination impacted older generations, these kids will grow up in a world shaped by a tragedy that they never witnessed.
