Without the bill of rights, there would be no established set of rights given to the people. Without it, there would be no precedent for the rights of the people, and thus the rights of the people could be bent to whatever the people in power wanted.
OK, so here are some ideas for the photographs
Causes:
Try finding some images of propaganda posters and explain the impact they had on the Jewish community. Then maybe get a picture of Mein Kampf and explain the ideas Hitler was trying to portray in it
Main Events:
Here you could get a picture of a Jewish identity card and explain how the Nazid used them. You could also get a picture of a concentration camp and talk about the horrors that occurred in them.
Consequences:
Talk about the memorials dedicated to the fallen Jews in the Holocaust, for example Yad Vasheem. You could also talk about the creation of the state of Israel by the UN after the Holocaust.
To answer the "call to action" talk about the "UN Convention on Genocide" document (search that up) and how it helps to prevent genocides. Add some personal opinion in this section
Good Luck
