In addition to the Freedom's Song video, Farmer's Insurance has produced other videos that are excellent. One of these, Ordinary People Doing Extraordinary Things, is available for you to view online. You can also order a DVD to keep in your classroom.

The video is only 4 minutes long and shows images of great men and women in history. Using written text and music, it tells how these individuals thwarted their circumstances to create great change in the world. I think the video might be a great culmination of a service learning unit. Students will see that what might not seem like a lot at the beginning can truly be the beginning of something great. I think this video is particularly good for students who are from at-risk environments including those who have special needs. Enjoy!
