I'm having a lot of trouble deciding what I should do my major work on ... i haven't decided any specific area let alone question ... and I'd be interested to hear the kinds of things that other people did If you can help please do!
A friend of mine did his major work on whether the USA should have kept going on into Iraq after liberating Kuwait. It was really well done, very interesting and quite relevant to what is happening now on the international stage.
I was doing history extension, but dropped it after a term because I thought it was just too much work for one unit. It was the only one of my 18 units that I ended up dropping (excluding D/T which I dropped on day 1 of year 11 to do Modern History).
I did mine on Ned Kelly - it was pretty sweet, looked at how different historians have portrayed him, through The True History of the Kelly Gang, Nolan's paintings, websites, newspapers of the day and that sort of stuff. I found it intersting and i got 38/40 for it.
