Sources of information.

You should use at least five sources of information. Textbook may be one of them.

DONOT use Wikipedia as a source. Wikipedia is an encyclopedia written by readers and edited by other readers, and it may include wrong information or false claims. However, you can use this site to direct you to other sites. The most reliable sites are the sites of scientific societies (American Society for Microbiology, for example), government agencies (such as CDC, NCBI and so on), museums and educational institutions (colleges and medical schools). The easy way to remember which sites to use as a source of information is to research only those sites which domains are .org, .gov, or .edu. The exceptions are the manufacturer website and reputable publishers such as New York Times http://www.nytimes.com/, Scientific American http://www.scientificamerican.com/, National Geographic and such. Remember to include the full address (URL) of the page you used as a source of information, and information retrieval date.

Format

The essay should be typed, single-spaced, 12 points font size, 3 pages of the text minimum excluding the title page and the reference page.Avoid direct quotes and explain ideas from a book/article in your own words. Remember, when you write about ideas from articles and books you are working with, you MUST include citation for these. Even if you explain in your own words what a particular writer has written about the topic of your essay, you MUST put the author’s name and the year of article/ chapter/book in parenthesis at the end of the sentence.
