This project can be used for any subject/any grade/any class. I created this project for my tenth grade world history class. The students create clues (the facts) to create a mystery. The mystery can be any topic you are studying - historical events, people, concepts, etc. On the preview, you can see two examples my former students created.
After each student/group creates the project, they will travel around the room putting together each group's clues to determine what the mystery concept/topic is. Student will take notes as they move around the room. I used these notes on their test (holds them accountable).
You could use this project for a fun bulletin board activity. Students can put together the clues to solve the mystery.
