Yellow and blue balloons floated through the sky Wednesday in Boston's Dorchester neighborhood, released by students there to honor the victims of the Boston Marathon bombings and the first responders who ran to the aid of the injured.
At a school ceremony, students sang about peace on the second anniversary of the attacks - a day that is now known as One Boston Day.
The goal is to shift focus to helping others by taking part in acts of kindness.
"Thanks for helping all the people that's in Boston," said young Brooklyn Marcos to the city's firefighters.
Students delivered cards to firefighters in Boston's North End to say thank you. Boston Police in Charlestown received cards and lunch from students there as a sign of appreciation.
Nearby, Spaulding Rehabilitation received a new wheelchair-accessible van, thanks in part to a grant by the Travis Roy Foundation.
Roy says he knows first-hand the hard work and compassion it takes to recover from a serious injury.
