Lab Report Assignment for Materials Science: 57:015  

This and other course materials available at the CTC website

The Materials Science course demands writing in two different formats: the lab report and an independent project.

Important: Although you may do the work of the labs with others, you must write a report on your own. The report measures your individual understanding of the lab. The report also measures your individual ability to communicate your understanding of the lab to others. Copying of the written work of others or any collaboration with others on writing the report may mean that you receive no credit for the lab. In addition, you may be charged with plagiarism and your teacher or the University may take further action. If you have questions about understanding and avoiding plagiarism, go to the CTC home page (http://www.engineering.uiowa.edu/~ctc/) for further information or consult the Student Academic Handbook, (http://www.clas.uiowa.edu/students/academic_handbook/ix.shtml). You may also set up an appointment to speak with someone at the CTC, which is located in 2224 SC, (in the Student Commons). Drop-in hours are from Monday to Thursday, 1:30 - 4:30 p.m.

The Lab Report

·         Materials Science requires five traditional experiments.
(See the Materials Science web page for descriptions of each experiment. http://css.engineering.uiowa.edu/~matsci/.)

·         Turn in lab reports at the beginning of the lab period on the due date listed in the Laboratory Schedule. 

·         Only use Materials Science laboratory equipment with a TA present (for your safety and that of the equipment) and only during scheduled laboratory hours.  TAs will not be available at other hours for these studies. 

General Formatting Instructions

·         Double-space the body of the paper, with 1" margins all around. Times-Roman font, 12-point only.

·         Label each section with the titles listed here: Abstract, Introduction and Background, Experimental Methods, Results, Discussion and Conclusion, References, and Appendices. Section titles should begin at the left-hand margin. Double space after the title.

·         Laser print and staple the entire report.  Do not use plastic covers or other binders.  We will provide Manila file folders to store the reports and other writing assignments. Important: Be sure to put your lab section on all reports.

Keep all drafts, the writing evaluation sheet, and the CTC Contact Report slips in the folder provided.  Submit your folder with each report and the final project.

The Writing Process -- What you need to do.

Write lab reports that colleagues and supervisors can easily understand.  Clear writing is an essential engineering skill. You must present the material in a coherent manner so that any engineering colleague can easily duplicate the experiment. To that end, organize your lab report by sections in the following manner: Abstract, Introduction and Background, Experimental Methods, Results, Discussion and Conclusion, References, Appendices.

Abstract:  A good abstract summarizes the report in a paragraph and generally answers the following questions:

·         What purpose did the lab have?

·         For whom did researchers conduct the lab?

·         What materials did researchers use?

·         What tests did the researchers perform?

·         What result(s) did they find?

Note: The abstract is your report in miniature. Although it appears first, common sense dictates that you must write it last.

Introduction and Background

An introduction gives the reader a "first impression" and should generate interest in the reader.  In this section introduce the subject of the lab and describe the problem the experiment wishes to solve.  The introduction should also include definitions of technical terminology.  It may also include who conducted the experiment, where they conducted it, and the date when they conducted it.

The Background section should include theoretical values for material properties such as tensile strength, hardness, coefficient of expansion, etc. You also need to specify the materials tested, including specific alloy composition and/or polymer type. Relevant equations also go in this section. Use a format similar to that in the textbook - briefly describe the equation before showing it and use the equation editor in Word (Go to the "Insert" menu, choose "Object..." and scroll down to select Microsoft Equation 3.0").

Experimental Methods

This section describes in detail the test(s) you conducted and the methods you used to set up, calibrate, and run the equipment. Include any pertinent illustrations of the equipment used, and make sure you caption them correctly.

Results

The section summarizes the major findings of your analysis.  Include values you calculate and/or measure.  Where pertinent, represent your data in a table or a graph.  However, graphs or tables must be preceded in the text by a brief explanation of the data they exhibit.  

·         Labels: Label all graphs and figures as Fig. #.  Label all tables as "Table #."  Note that graphs are not labeled "Graph."

·         Include important tables and figures in the text of the report and not in the appendix.  Raw data and less important figures and tables can go in the appendix.

·         If you include a table or figure in the body of the report, you must refer to it.

·         Graphs and figures must have a descriptive caption below the figure. Tables must have a descriptive title.

Example:  Fig. 1: A graph of hardness versus tensile strength of 6061 aluminum

If your results involve "before and after" experiments (e.g., before and after heat treatment), or if you are looking at changes in measured properties, express them as a percentage change as well as listing the magnitude of change.  For example:

Table II: Hardness test results of 1018 steel before and after water quench

Hardness before Treatment (HB)

Hardness after

Treatment (HB)

 % change

         45

          60

  +33.3%

         45

          42

    -6.7%

Discussion and Conclusion

Discussion:  Include additional analyses or experiments needed to improve upon your results.  Describe any assumptions you made and indicate how these assumptions affected your results.   

Conclusion:  The conclusion offers you an opportunity to provide new perspectives on your experiment.  Do not simply repeat information in your introduction. Include a brief (two to three sentences) summary of the report.
