Andres Chavez can't remember what he did on September 11, 2001. Nor can he remember where he was, what he wore or even what else happened that day.

Chavez doesn't suffer from any memory-altering condition that makes him forget events that happened in past. No, instead, he was just a few months old the day the planes, piloted by terrorists, were flown into the north and south towers of the World Trade Center.

"I believe it's a very sad day in our country's history," Chavez said. "But it's a very patriotic day, because we had so many people just stood up from their chairs and seats at home and just took a stand."

Born the same year, the Stockton Edison High School junior, is a sponge wanting to know details of attacks.

Even though students like Chavez were just a few months old — or, in some cases, not yet born — they appreciate and want to learn the significance of that tragic day.That's where Angelo Sandoval comes in.

"I always ask the students, ‘what year were you born?’” said Sandoval, Edison High School’s history department chair and teacher. “And then this year when they said 2001 that's always my thought was you were born the year of 9-11."

Sandoval said he has to teach about the events of 9/11 "carefully" to his students.

"You have to inform them what happened and also to understand the depth and the magnitude of the event because I don't think they understand how big of an event it was and how it changed our country," Sandoval explained.

Upon learning about the events surrounding 9/11, juniors like Jovalynn Hensley are surprised by its magnitude.

"I never thought that something like that would actually happen," Hensley said. "I never knew it would go to that extreme."
