For Thursday, read two op-ed pieces from The New York Times. First, read this piece about Georgetown University's involvement in the American slave trade. Then, read this piece by a woman whose family was enslaved by Georgetown.
If you have time and interest, you could also watch this video from The New Yorker magazine (it's about 12 minutes long) about a Louisiana museum that tries tell the story of slavery, and read this essay from The New York Times Magazine titled "The Condition of Black Life Is One of Mourning."
