Children traveled back in time this week to celebrate a milestone birthday for Seminole Elementary School.

The school turns 100 years old, and students marking the centennial during a special ceremony on Friday thought that was pretty darn cool.

"It's 100 years old, and I like stuff that's ancient," said second-grader Amelia Longboat.

"We wrote all about what school was like through the decades," one teacher explained, holding up a student-made book called "A Travel Through Time."

Still, it may be hard to imagine studying up on subjects like hygiene and penmanship — which appear on an old report card from when the school opened in 1915 — or coming to school without any shoes, on horseback.

"Some of the kids walked to school. Some of them rode horses. Some of them were in buggies," said Principal Diane Cato.

And they all learned in the same building — all 25 of them. Not a lot of children back then, but that's not shocking to the present-day principal.

"There were only 70 people in all of Seminole," Cato explained. "There was really nobody here."

When the school was built, the area wasn't even called Seminole.

My, how it's grown.

"Remember that picture? Well, we are standing right where those children stood," a teacher explains to students outside Seminole Elementary during Friday's ceremony. "The old difference is it's not 1915. It's 2015."

And in 2015, the students and faculty got the history lesson of a lifetime.

In honor of Seminole Elementary School's 100th birthday, school leaders added a new roof, replaced windows and renovated the original, century-old building. The Pinellas County School District alotted $300,000 for the project.
