Tuesday marks the 17th anniversary of the September 11th attacks which left nearly 3,000 lives lost and families broken.
Some people who are alive today and learning about what happened on that day weren't born when it happened.
Like all 8th grade students, Isabel Dawson wasn't born to remember the deadliest day in America, September 11, 2001.
She and her classmates at Anza Trail School in Sahuarita turn to the educators and those who were alive to share their stories. "I talk to my dad he's from New York so it was a huge shock," says Dawson.
"I think the first time I started learning about it was in the 1st grade when our teacher just briefly explained what happened. But then in Middle School, we got a lot more depth and started looking at videos and documentaries."
For 8th-grade Social Studies teacher Derek Kieninger, he says he builds up to 9/11. It's like connecting the dots - starting with the 1980's all the way to the present day.
"When we get to 9/11 we talk about the day itself. The events and talk about the reaction and how it led to such patriotism. I remember when I was a kid you couldn't walk down the street without seeing an American flag on everyone's house or on every street. We then look at how the laws and things came from that and how it leads to today and the current war on terror," says Kieninger.
It makes it real for students after more than 3,000 lives were lost on that day.
"It shocked everyone in the class - I remember watching the documentary and there were kids crying because of what happened. It's just scary," says Dawson.
