It is one of the worst school shootings in U.S. history.
Thirteen people were shot and killed at Columbine High School in 1999.
The affects of this shooting will be felt by many for years to come, but one student's message of kindness and respect still lives on, more than eleven years after her death.
It's a simple challenge that Rachel Scott lived by, be kind to everyone.
With the recent events of school bullying across the nation, many people say this message could not have come at a better time.
“The negativity, the internet bullying, just the disrespect sometimes that goes on at school districts. It’s so encouraging to have a program that's not telling them not to do something, but encouraging them to treat each other with kindness and compassion and realize why that is important,” Gretchen Reed said.
The challenges encourage students to not only treat other well, but live a positive life filled with love and respect.
Many businesses, schools and families have incorporated Rachel's message into their curriculum...
“We try to approach it as Rachel's challenge talks about in a positive way and be proactive rather than reactive. We try to stop it before they ever start,” Principal Thom Cochran Highland Elementary.
Although Rachel's life was taken away at a young age her message continues.
All elementary school students in Johnson County gathered at Highland Elementary School to watch the presentation on "Rachel's Challenge."
Johnson County High School and Middle Dchools took part in a similar activity earlier in the year.
