The first thing I would say to do is visit the Rock and Roll Hall of Fame. It may seem to be a little to old for them, but I know when I was younger it was always neat to see famous people's old things. There is also the Great Lakes Science Center.It is located very near to the the Rock and Roll Hall of Fame.
This Science center is cool in the fact that there are hundreds of hands on experiments and activities for the kids to do! There is also an IMAX theater here. Here's a picture of the Rock and Roll Hall of Fame, the Great Lakes Science Center, and the Cleveland Browns Stadium.
All 3 are next to each other on the bay. Also, right there, is a Firefighter memorial that is really cool to get pictures of.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
