You are required to keep a research-style laboratory notebook with duplicate pages and to record all your experimental conditions and original observations while working in the lab. This is required writing each week but it is minimally graded. The point is to form a good habit for your future scientific research work. The directions for keeping a laboratory notebook are given at the end of this document and you are encouraged to peruse the research notebooks from Linus Pauling (one of our most famous alumni) online at: http://osulibrary.orst.edu/specialcollections/rnb/index.html.
The written work required for this writing intensive course fall into the following types:
A. Full Written Reports include the following sections (the % numbers in parentheses indicate the portion of the mark of the report assigned to each section):
I. (10%) Introduction: Explain the objectives and rationale of the experiment.
II. (10%) Experimental: Briefly describe the instrument, summarize important reactions involved and changes from published procedure (sufficiently that a layman could understand what was done).
III. (15%) Results: Present your results in tabular and/or graphic form as appropriate. You may use printouts of sections of your spread sheet calculations but make sure that headings are provided so that it is clear what the numbers represent.
IV. (20%) Calculations: Use complete sentences to explain calculations. Give equations and sample calculations. If in doubt about a result, see the instructor before submitting your report. (Don't wait until the last minute!)
V. (15%) Errors: Give the standard errors from any least squares fits of your experimental data. Beyond this, briefly discuss where you can the likely errors involved in the measurements and their effect on your results.
VI. (25%) Discussion: This is the most important section of the report since it gives you an opportunity to show originality in thinking about the results and in offering your interpretations. Explain clearly the significance of the results and offer comparisons with primary literature values for data and results on similar molecules if possible. Answer all questions posed in the manual. Discussion of problems encountered and possible improvements or extensions in the experiment is encouraged.
VII. (5%) Primary and Secondary References: List primary and secondary references from the scientific literature (not the lab manual) used in the preparation of your report using journal style format (see for example, Chapter 6 of the ACS Style Guide).
Full reports should be complete but concise and conform to the normal standards of scientific journal papers. They should be printed with all necessary graphs, sensible portions of spreadsheet printouts etc. fully labeled and explained, with scientific reasoning and discussion. You will have the opportunity to revise some of your writing after the instructor has reviewed and commented on it.
B. Short Reports that encompass some fraction of a full report.
C. Spreadsheet Exercises.
D. Data Summary Sheets.
A passing grade requires successful completion of all experiments and all reports. All reports are individual efforts but during the lab meeting you will work in groups.
Grading emphasizes accurate measurements and detailed answers to questions posed in the lab manual. The overall grade for the course is based on the written laboratory reports as shown below.
Late reports will receive a 10% decrease in maximum points allotted per day late.

This is a Writing Intensive Course and satisfies the WIC requirement for majors in the Department of Chemistry. Students from other majors and graduate students who elect to take the course are expected to meet all course requirements, including writing. However, this course does not satisfy the WIC requirement for majors other than Chemistry. Because this is a writing intensive course, students will:
· use writing as a way of learning course material
· learn and practice writing as professionals in the field of scientific research/composition/education
· complete informal, ungraded or minimally graded writing assignments
· complete formal, graded writing assignments which are taken through the full writing process, including drafts and revisions
· receive and give peer feedback on writing in progress
· revise and polish at least 2000 words of writing (8-10 pages)
· complete a total of at least 5000 words of assigned writing.
Texts and Learning Resources:
Writing Guide for Chemistry should be consulted as an overall guide to professional writing in chemistry. It is free and posted on the departmental web (see http://www.chemistry.oregonstate.edu/writing/WritingGuide2000.htm).
The ACS Style Guide, A manual for Authors and Editors, Janet S. Dodd, Ed., American Chemical Society, 2nd Ed, 1997, is a required text for this course. This is a reference on professional writing for chemists.
