It’s Constitution Day — and the most momentous one yet for 16-year-old Adalia Jimenez.

The Montgomery County junior was selected to interview Archivist of the United States David S. Ferriero as part of a Constitution Day event that will be live-streamed Wednesday. It is sponsored through a partnership of the White House and Discovery Education, with 13,000 classrooms signed on, Discovery officials said.

The teenager, from James Hubert Blake High School in Silver Spring, said she is a big fan of history and thrilled to be honoring it on a national stage.

“I love history in general, I love everything we talk about in our past and I love that we can learn from mistakes,” Adalia said, adding that she has taken history and government classes and especially enjoyed learning about “the struggle for our rights and our liberties.”

The 11th grader said some of the questions she would ask Ferriero were submitted by students from around the country, and some are her own. She thought it best not to be too specific.

“You’re going to have to watch it to find out,” she said.

The 30-minute live webcast, which starts at 1 p.m., also includes a short lesson on the Constitution and a video highlighting the tour Adalia and two other students took of the National Archives last week.

Adalia said she was impressed by the visit — her first — and recalled seeing letters for and against allowing women the right to vote. “It makes me appreciate the rights I take for granted,” she said.

Adalia was selected as the student interviewer from a group of candidates after Discovery contacted Blake Principal Christopher Berry about the event.

“She is a nice balance and combination of intelligence and poise and being well-spoken,” Berry said. “We’re all thrilled for Adalia.”

On the eve of the big interview, Adalia said Tuesday that she was more eager than nervous. Active in theater and an a cappella chorus, she is used to being onstage. She said she has sung the national anthem at about a dozen Washington Nationals games.

“It’s a great honor,” she said of the Constitution Day event. “I couldn’t ask for anything more.”

As for her future, she added, “I’m hoping I can do something that involves history and broadcasting and, if I can, theater.”
