Cut apart the categories and lay them out in order. Students divide into 4 or more groups. Take turns picking categories until all copies of questions are passed out.
Students can take their chosen categories home or do in-class research.
All groups will have some of the same questions to research. We've tried to design the game so the questions provide as much information as possible. First group picks a category, and gets a chance at question 1, etc. Answer questions for 1 point each. If a team answers a question correctly, they get another question in the same category.
