Assign students specific roles and have them research what their character’s position on the petition was (were they a signatory? How did they react to the presentation?).

Students simulate a meeting of Scientists presenting the petition to Oppenheimer.  Each student is assigned to represent a specific person involved in the Manhattan Project (Szilard, Oppenheimer, Groves, Teller, etc.) or a signatory to the petition (Einstein, etc.).  This exercise will have students simulating a meeting between these men to discuss the petition and its validity.  Students should all enter the simulation with the same background information, with the instructions not to research what actually happened with the petition so as to allow them to come to their own conclusions on the report.
