BINGHAMTON (WBNG) -- Tuesday marked the 15th year that Calvin Coolidge Elementary School participated in Jump Rope for Heart.
Children of all grades formed teams of three. Then, each team member jumped for one minute before trading off to see which grade level could jump the longest.
Organizers said the event teaches students about staying healthy and raises money for the American Heart Association.
"Think of the education the doctors need, the tools, the expenses; that's why we're jumping. And it clicked and they thought you know, 'we can make a difference," Physical Education Teacher Adana Brauer said.
"When you jump rope, it makes you more stronger," Second-grader Kiara Jones told 12 News.
Since 2001 the students have raised more than $53,000 through Jump Rope for Heart.
