The Red Scare: Classroom simulation!
In this educational simulation, students each research a different character secretly. One of them was a genuine communist, the rest were innocent of the charges. Then, after each one is interrogated (HUAC style!) by the teacher, students have to organise themselves over several rounds into different groups in an attempt to identify the communist within the group. A great one-hour activity! There is also a PowerPoint presentation about some of the key characters outlined in it to share with students afterwards.
