Typically our daily holiday' is on a lighter note.
But of course it is september 11th.
It has been 18- years since terrorist attacks killed nearly three- thousand people in the u-s.
There will be ceremonies today at the pentagon ... at ground zero' in new york city ... as well as in shanksville, pennsylvania.
----- many of us will always remember where we were on september 11th, 2001.
But as i mentioned ... it has been 18- years since that day.
This morning we're learning how new jersey high schoolers are doing their part to never forget' ... even though they hadn't even been born at the time of the attacks.
Here's c-b-s' lisa mateo.
With each flag, a moment to reflect about those who lost their lives on 9/11.
Thank you students are planting 2,977 flags on the front lawn of cedar grove high school in new jersey.
One for each person killed in the terrorist attacks.
More than 90 countries lost citizens.
Junior brian catanzarite doesn't remember that day.
He wasn't alive 18 years ago..
But this display helps convey the impact on so many lives.
Not only is it a person it's the whole family so you just want to keep in mind why you're doing it and who you're doing it for.
It hits close to home for senior francesca catrone.
Her father has told her about working downtown on 9/11.
He saw the buildings collapse and to think that this could be happening right now in real life and to put that into perspective now in its fifth year, cedar grove waves is organized by resident and parent david schoner.
When you come here you see the magnitude of every flag, it stays with you and it causes a conversation.
"a new addition to the project last year, a four- foot piece of steel from the remnants of the world trade center."
I can't recreate for you what most of us experienced.
The conversatio n continues inside..
Where students get involved in presentations for their classmates.
Principal richard mangili says it's an important part of the school's 9/11 remembrance.
We want to educate our students and never forget our victims. cedar grove students are learning where their responsibility begins.
As we get older it will be our job to tell the story of what happened.
And the flags honoring the victims..
Will help them tell the story.
