  1. Lab Report Writing for Materials Science Sarah Livesay, HCTC Assistant Director

  2. Lab reports have the following purposes: • To explain the intention of conducting these experiments. • To lead readers step-by-step through your methods. • To display and discuss the results. • To provide plausible reasons for readers to accept your conclusions. • To narrate the story of the experiments. Purpose of Lab Reports

  3. A concise Abstract could be reviewed and acted upon by a top executive. • The Introduction and Background and Conclusionsections provide non-technical detail and narrative for a general audience. • Professionals in your field will understand and could duplicate the experiment from your Experimental Methods, Results and Discussion,andAppendicessections. Section Style Overview

  4. Write report on your own • Do not copy others’ work • Do not write collaboratively • Cite all sources • Apply quotation marks when using sources verbatim Avoiding Plagiarism • For more information on avoiding plagiarism, see also: • Understanding and Avoiding Plagiarism (HCTC). • Source Use and Plagiarism Policy (HCTC). • Student Academic Handbook (University of Iowa).

  5. Use complete sentences. • Attend to verb tense. • When discussing what was done in the lab, use past tense. • When discussing the purpose of the lab and your conclusions, use present tense. • Write in third person. • Do not make bulleted lists within the body of report. • For specific guidelines on using tables and figures, see Materials Science Lab Report Style Guide pp. 3-4. Writing Guidelines

  6. Strong Verbs

  7. Abstract should address these five issues: • Who requires these lab tests and why (present tense) • Purpose and scope of tests (past tense) • How the tests were conducted (past tense) • Results (past tense) • Conclusion/Recommendation (present tense) Abstract

  8. Introduction: • Introduce subject of the lab • Describe problem that the experiment attempts to solve • Include definitions of terminology • Include who, where, and when Background: • Include theoretical values for material properties (tensile strength, hardness, coefficient of expansion, etc.) • Specify the materials tested • Introduce equations Intro-duction & Back-ground

  9. Describe: • test(s) that you conducted • methods that you used • Include pertinent photos or illustrations of equipment used • Place titles above tables • Place captions below figures Experi-mental Methods

  10. Summarize major findings • Include values calculated and/or measured • Indicate additional analyses or experiments needed • Describe assumptions made • Represent data in a table or a graph (if needed) Results & Discussion

  11. Include a two- to three-sentence summary of the report • Tell a (brief) story of the experiment • Make a recommendation Conclusion

  12. Create your reference list in APA. Use the APA Documentation Guide, which you can retrieve online at Purdue University’s Online Writing Lab. References In-text: The aluminum alloy 2024-T3 has a hardness of 120 using the standard Brinell hardness method (MatWeb, 2007). References: Callister, William D. and Rethwisch, David G., (2008). Fundamentals of Materials Science and Engineering(3rd ed.). New York: John Wiley & Sons, Inc.

  13. Include bulky materials that may not contribute to the overall report • Title each appendix (e.g., “Appendix A: Tables” or “Appendix C: Example Calculations”) Appendices When in doubt, include it!
