Most people can remember where they were or what they were doing on September 11th, 2001 but not all.
Kids in 5th grade right now weren't even born when the attacks happened.
All of the students in Mr. Hunter's 5th grade class at Riverside Intermediate School were born after September 11th, 2001.
Some 6th graders at Riverside were also born after that day.
Dane Funston is a 6th grader and he says, "I know that it was a terrorist attack on the twin towers in New York City and thousands of people died and that was really sad."
The 5th graders got together Wednesday to brainstorm facts that they knew about the attacks and then the teacher asked them how they first learned about 9/11.
One student said they hadn't heard about it before Wednesday.
Others said they found out about it from books or T.V.
Anja Houin says, "It was 9/11 and at school we were learning stuff and so I went home and asked my mom and dad what it was about and they told me what it was and then I looked up videos about it."
Some students say it's sad but they would rather not focus on the negativity of 9/11.
They point out that sometimes tragedies can bring out the best in people.
Madison Stiles says, "It's good to think about the survivors and the heroes of 9/11 and how they helped everyone."
Many of the students are still learning the details about the attacks.
Some couldn't remember the other places that were attacked besides New York City and others weren't sure if this was done on purpose or not.
Why was the most common question.
Tallulah Gauld says, "It was really sad. Lots of people lost family and it must have been really weird and crazy to watch it happen."
Funston says, "I hope that nothing ever happens like this again."
The school librarian tells me that all of the books about 9-11 were checked out by students.
Some students say they look forward to learning more about September 11th, 2001 and one girl says she wants to some day go to the 9/11 Memorial and Museum.
