I will be going to Copenhagen on the first leg of my trip and will be there a little more than a week, but I would like to know if there are any popular, or easy day trip to Sweden, by train or other means?
It's easy to get over to Sweden now that there's a bridge/tunnel for both cars & trains from Copenhagen to Malmo. I think you can also still take a hydrofoil from the Nyhavn Canal over to Malmo (it docks by the Malmo train station). If you go up to Helsingor to see Hamlet's Castle, you can take the short ferry boat ride over to Helsingborg. I did a day trip to the university city of Lund which is very nice.
