The vietnam war was happening during a huge cultural change for America. Its a really interesting social time for the states.
I don't know as much about the Persian gulf war, wich may be a good reason to do a report on it since it isn't as well known. Its a lot easier to impress teachers with facts they don't already know.
The salem witch trials were f'ed up. Basically a bunch of Puritans (not sure if thats right) didn't know why bad things were happening so they started hanging women. I belive thats the cause of the whole fiasco.
What kind of class is it? Social Studies I take it?
