Im currently rounding off a Masters in Geography, and preparing to do a PhD, so i might be able to help you but then i dont know what your teacher expects from the paper, or what level you are writing at.
generally speaking the way i go about writing essays and papers it this: start at the end and work backwards.
Come up with three or four key points, these are your conclusion. SO these points might be something like: Hawaii is idealised in film to make it look like paradise, but this is'nt necessarily true. Hawaii's charasmatic features such as its beaches and volcanoe are often focused on, because these are associated with a fragile paradise etc.
Its often easier to get to these points if you have some questions you want to ask first like: does the media give an accurate representation of Hawaii and its geography, if not why? Have humans destroyed Hawaii from what it once was? HO do the people of Hawaii deal with their volcanoe and tsunamis? Remeber to ask why questions? If you cant find any film showing rain in Hawaii, why is that?
once youve got your questions and the key points to answer them start ordering your evidence around them. So look though films, tv shows documentaries. Try looking through footage from different eras to see how Hawaii has changed, or peoples view of it has changed.
once youve got your evidence, points and questions i usually order it something like this
Introduction: explain why you are researching this, then say what your goin to say -tell the reader what each section of your essay is going to be about.
point 1 - say what the point is with a sub title, then either write paragraphs describing your evidence/ show some photos, or graphs and tables. Once youve laid out your evidence give some interpretation that leads you back to your key point.
repeat this for two or three more points depending on word count
conclusion - summarize your points
