Write 4 papers about a physics topic ( you must know physics )

Write a paper of about 1000 to 1500 words in length.
You may use source material from the web (including wikipedia), however you must write in your own words.  
Short quotes of less than 10 words must be in quotation marks and properly cited.
Longer quotes (if necessary) must be indented as a separate paragraph with offset margins wider than your normal text.  Such quotes must also be properly cited.  
Any idea not your own must be cited as well, even if it is not a direct quote.
Including figures and/or diagrams is a good idea, but they must be explained in the text.
Include a summary-critique of your sources at the end.  Was the physics presented correct and understandable?
Here are some suggested topics:

1)Take a side on global climate change. Explain the physics and evidence from your perspective.  On this one, be sure to consult many sources.  Stay away from personal blogs.

2)If you were president of the US, what physics item would be your greatest concern?  Why?  Explain the physics.

3)Choose an object/experience from your daily life and explain how it works from a physics perspective.
