Hey everyone, So I'm currently getting ready to teach a subunit on the United States for my Geography class. I plan on: - showing a documentary that provides a nice overview of the US - maps, of course - Analyzing Wal-Mart's impact on Idaho potato farmers - Alternative Energy - Trans-Texas Corridor proposal/North American Union - Survey of our national parks and project But outside of that, I am kind of at a loss as far as specific issues. I would really like to cover more but the country is so broad that I'm having trouble narrowing the content down. I would appreciate some help, like- is Niagra Falls in danger? Or Manhattan in need of drastic changes? Las Vegas facing a water shortage? stuff like that. Are there any topics of discussion you think would benefit this class? Thanks in advance for your help.
