The project began after the Church of Jesus Christ of Latter-day Saints Kaysville Stake learned that the schools were in need of some yard work.
"We spoke to the school district and found out that there are things that they just don't have the time to do," said Anderson. "So we decided to help."
On Saturday, the 250-plus teenagers split into groups of about 40, working at Kaysville Elementary, Columbia Elementary and Kaysville Junior High.
They pulled weeds, swept various walkways and even worked on Kaysville Junior's soccer field.
And when they were done with the schools, their service didn't end; they began working on their neighbors' homes.
"I think it's cool that we're making the school look nice," said Brodrick Brown. "I think we all just hope that when the kids come back after summer, they'll have a nice first day of school."
"I like knowing that we're helping the community," said Emily Butterworth. "I hope that our work will make the schools a better place for the kids."
"I think it's great that we're making the school look so much nicer," said Missy Smith. "It really means a lot to young kids who still really like going to school."
"I think that it's also important for the teachers," said Maren Johnson. "They did so much for us when we were here, now this is our chance to give back to them."
"What I found amazing was that throughout the day, not one kid complained, and it was hot," said Anderson. "They kept working, and when they finished what they were doing, they found something new to do."
"The youth around here are so happy to help and they're always getting out there and getting involved in the community," Anderson continued. "They really understand that service is a critical part of life, and I just think it's great."
