This ppt. lecture chronicles the stages in the journey of a slave from capture all the way to their new life in the colonies. I have tried to emphasize the horrible reality of slavery for those who experienced it. At the end is also a link to a free summary video clip from "Crash Course."
I also recommend having students play an online simulation from mission-us.org entitled, "Life of a Slave." Very well produced and free.
