what do i already know?

Hi,
 this is our second essay of the class. i am going to be comparing and contrasting the 1920's and the 1930's. this is what i already know

         1920's:
             - called the roaring twenties
             - great economy
             - ended the Prohibition
             - lavish wealth
             - a luxurious time period
             - end of the decade lead to the great depression

        1930's:
             - the great depression
             - the worst financial fallout to date
             - lead to the world war two
 there are still so many things that i still need to know about these two decades, if you have anything to add please tell me.
