Instructions for Writing Assignment

Chemistry 431C


A paper will be assigned to you from the instructor.  To get feedback on your writing please submit a rough draft first to the Writing Center located at the library (x35350, Lib PW 2097).  Once you have received feedback from the Writing Center you may hand in the corrected draft, proof of Writing Center review, and original research article to the instructor by May 14 for more feedback.  The final draft is due May 25, at the beginning of class.  START EARLY!!


Instructions for Writing Assignment


Write a minimum three page summary of the paper assigned to you.


In the summary include: 1) a description of the hypothesis being tested; 2) a description of the results (it is useful to describe each figure or table); 3) the major conclusion of the work; 4) a new question that builds on the article’s findings.  The paper must be written in your own words.  Do not attempt to plagiarize; if you do you will get a zero on the paper and you will fail the course.  The paper and a photocopy of the original research article must be handed in together.  Only word-processed papers will be accepted.
