Information Literacy Session II:

Evaluating Resources



The debate over crop circles continues to this day.  Are they plasma vortex phenomena?  Do they originate with the wind or with the earth's magnetic fields? Are crop circles the imaginative creations of midnight pranksters?  Are they alien calling cards from outer space?

You have been asked to write an argumentative paper discussing whether or not crop circles are increasingly sophisticated messges from alien visitors. You will need to research both sides of this question and decide whether you support this possibility or not. Consider the following topic in a 3-4 page paper utilizing a minimum of three high quality resources and addressing this argumentative statement:

Crop circles are messages from

alien visitors.
