Having been a foreign exchange student I think this is a really cool approach. There´s plenty of cool things to bring up, for instance their crazy current King Carl Gustav, ABBA, Swedish conservative-christian-closed-fascist-folksinger Carola, their history of neutrality in armed conflict (all though just knowing the basics like capital, population etc will be intriguing enough). I don´t know if there´s help in any of this, but I´ll post it anyway.
Interesting recent fact: The minister of commerce in Sweden had to resign because of possible fraud and black labour. The minister of Cultural Affairs had to resign on account of several matters. This happened earlier this year, both within ten days after the newly elected government took office.
I´m Scandinavian myself, though not Swedish.
