Here is an example of looking at current news stories and generating assignment topics from the front page of The Seattle Times newspaper homepage-- keep in mind that some topics will be more informative (outlining a new or relatively unknown topic), while others will be more argumentative (any "opinion" piece, or a story discussing what "should" be done about an issue).
Research is a process.
Step 1: Understand your assignment
Step 2: Start with a general topic idea
Step 3: Find information
Step 4: Evaluate
