I take the last nine chapters from Holt's "Sociology: The study of human relationships" and assign them to nine groups of students. Each student is required to do research specific to their topic and teach it to the class. This file is the direction sheet that is given to each group.
Then individual cards are given to each group that is unique to their topic and the information they must present to the class. Those are sold separately under a file called "End of the year project: topic cards"
