In this interdisciplinary grade 6 world history and language arts unit, students examine the fall of Rome (Italy). Working in teams to research the causes of Rome's demise, participants develop a theory explaining why Rome fell. The student guide provides detailed instructions on how to complete the activity, a list of resources, and includes Internet sites. The teacher's guide ties the unit to California state standards, provides adaptations for special needs students, and provides suggestions on how to conduct and evaluate the unit. (RJC)
