On April 20 1999, two boys -- Eric Harris and Dylan Klebold -- entered Columbine High School in Jefferson County, Colo., and fatally shot 12 students and one teacher. Twenty-four others were injured.

Rachel Scott, a 17-year-old inspiring writer and actress, was sitting outside the west entrance of the school eating her lunch when she was killed by multiple gunshot wounds.

Rachel was active in her church as a youth leader. She left the world with six diaries and several essays about kindness and how it could change the world.

Six weeks before the shooting she wrote an essay for school stating, "I have this theory that if one person can go out of their way to show compassion, then it will start a chain reaction of the same."

Rachel's father, Darrell Scott, wanted to get the word out about what his daughter was trying to say. He started a group called Rachel's Challenge, which visits schools, churches and other community organizations.

Rachel's Challenge came to Newfane High School last week. It was a very emotional and moving presentation. Students are told all about that day and how Rachel lived her life. They give you her codes of life and how a little kindness can go a long way. Rachel's five challenges are: eliminate prejudice, dare to dream, choose your influences, use kind words and start a chain reaction.

Months after the death of their daughter, Darrell and Beth Scott were moving furniture around and on the back of Rachel's dresser were her hands traced out. In the hands she wrote a message saying "These hands belong to Rachel Joy Scott and will someday touch millions of people's hearts."
