This is a fun prereading activity for The Crucible! After learning about mob mentality and mass hysteria, I have students conduct a mock trial where 5 citizens from the 1600s have been put on trial as witches suspected of murder. This can be adapted for different class sizes.
Students will take turns interrogating all 5 suspects. At the end of the lesson, every student will vote on those they think are guilty...only to find out that all are innocent. (I always tell the jury they only get points for the assignment if they identify the witch). This is a fun way to have students experience 'mob mentality' and mindset.
