I find that my students, even as seniors, have very little awareness of the world outside of their own country. The objective of this project is to force them to look at a variety of different countries to verify each country's government system, economic system,etc. They become familiar with the vocabulary of the unit and exposed to a variety of world societies through active research.
Students fill in a chart after researching a large number of countries, and then do more thorough research on three more of their choice. In my class, students use the CIA World Factbook as a start, and other sites as needed.
I am lucky enough to have Chromebooks in my classroom, so I share the document with my students through the Google Classroom. If you are interested in a digital copy after purchase, let me know and I will share one with you.
