You will need to do some research in order to complete this assignment.
For Internet searching:
At this webpage, you can go immediately to the search sites (first three columns across the top) -- or even better you can scroll down until you see the section called HOW TO SEARCH THE INTERNET. Those are the links to start with. You'll not only learn how to come up with good search terms, but also how to evaluate the webpages you get as results. Some will be good and others will be garbage. You need to know how to tell the difference.
For this particular assignment, you need to start out at http://scholar.google.com and enter carefully selected search terms.
Also ... do you have access to a college or public library? Even if you go to the library only once to get a library card/account, you may be able to get the passwords, etc., to access the huge databases most libraries subscribe to these days. You'll often find better information through them than through general searches on the Internet.
Here is an example -- one college's library website (but public libraries usually have many of these, too): (Broken Link Removed)
Click on Electronic Resources/Databases to see the different databases this particular college provides for its students. EBSCOhost, ProQuest, and Facts.com are among the largest and best.
What does your library provide? That's a good place to research.
