Two Freedom Project iReport videos have been nominated for the annual iReport awards.

South Korean teacher Sunny Yang pledged to "Take a stand against slavery" as part of CNN's Freedom Project and vowed to get her students involved in the cause.

She used a stop-motion drawing to show the difference that we can make in the lives of people living in slavery.

And iReporter Renee Hong created this video to draw attention to the problem of human trafficking. The video uses stop-motion photography and statistics to educate viewers in an entertaining way.
