After I teach about the Salem Witch Trials, I always like to prove to students that the hysteria and accusations they learned about are not unique to the 1692 Salem. This followup activity always helps. Students read a short summary about the communist hysteria of McCarthyism in the 1950's and the wartime hysteria of Japanese Internment in the 1940's. Students compare and contrast both of these episodes with what they learned from class about the Salem Witch Trials. They then answer a thought-provoking discussion question about what could cause a witch hunt today. During discussion, I make sure to address US fears over terrorism and immigration.
