This is a performance assessment activity where students will conduct an investigation into the triangle shirtwaist factory fire. It includes eyewitness reports, case records, photographs, building records and students look at the evidence and determine who is to blame, in their opinion and based on the results of their investigation. Everything is included in this zip file. I spent a lot of time pouring through the case records online and condensed into the version I am posting so it is reasonable for students to read and examine. I complete this activity before students go through the real events and outcome of case in the PPT and video clip I also have in the store.
