This document outlines a time travel roleplaying activity where students take on the role of Doctor Who and choose an event from the Modern Era (1945-1970) to alter. They will write an essay explaining the original event, how they changed it, and speculate on the ramifications of that change based on their research. Students are given options of events related to the Cold War, technology/economy, civil rights movement, and national politics to potentially alter. They will present their findings in an essay and timeline showing the original and altered timeline. Research rules require at least 5 sources, including 2 websites, 2 primary sources, and 1 book. Any altered timeline must be supported by research and show impacts on other related historical events.
