School Help- What's changed in the past 100 years

[Jesus Saves Gretzky Scores]

I have this assignment for school, it's about what's changed in America in the past 100 years, and how it's changed America. I was trying to do something political, but I could never find any information on what I was writing about, or it was relevant more than 100 years ago. Anyone have any ideas for me? Thanks!

Well, where do I start... How about the fact that it rose after the first world war to become a major power, even moreso after the second world war, and the supreme world power at the end of the Cold War.

It doesn't need to be America itself, but what technologies, society, politics, etc. have changed.

Nevermind everyone, my teacher helped me out. I'm doing it on Occupy now. Thanks!
