AN EXAMPLE LABORATORY REPORT by Cecil Dybowski dybowski@udel.edu CHEMISTRY 446 Here you enter the section and group numbers. EXPERIMENT 6 Here you insert the date that the report is submitted. Abstract The general format of a laboratory report is explained and illustrated. Each section is illustrated. Common errors and problems are discussed. Data analogous to those of experiment 6 are used to demonstrate a typical report structure. [NOTE: THE ABSTRACT SHOULD ALWAYS BE THE LAST SECTION ONE WRITES. IT IS A SUMMARY, WHICH CANNOT BE DONE UNTIL ALL OF THE WORK OF THE EXPERIMENT AND THE WRITING OF OTHER SECTIONS IS FINISHED.] Text in blue font indicates text that is part of the report. Text is black is commentary on how to write the report.

Example Laboratory Report 2 1. Introduction Writing a laboratory report is as important as taking data. When I say “writing,” that includes the careful analysis of data and attention to the details of how the information is formatted for the ultimate reader. Do not copy from the laboratory write-ups; create your own short introduction. The introduction should be concise. It should explain the outlines of the experiment, what results have been determined, and salient points about the experiment. It should be about how your experiment worked, not some reprise of the general statements in the write-ups. Remember that an introduction “tells the reader what he/she is going to be reading.” Here is an example of a concise introduction: The infrared (IR) spectrum of CO has been analyzed to determine the fundamental constants of the molecule. The results can be expressed in terms of the rotation constant, B e , the rotation- vibration constant, e , and the vibrational frequency. By IR spectroscopy on ground state molecules, it is not possible to determine the zeroth-order vibrational frequency, so we report the vibrational frequency, 0 0 2 e x . The results are consistent with data in the literature, within experimental error. The object of the introduction is to give the reader a sense of what you are doing, why you are doing it in the way you are doing the experiment, and what results you have determined. Since scientific results are considered to be independent of the observer, it is appropriate to state any differences between one’s work and that of others. It may be appropriate to give numbers at this point (as well as in a section labeled “Conclusions”, but it is not always necessary. 2. Experimental The section entitled “Experimental” generally contains information on the physical properties of the experiment, such as the type of instrumentation used, the variables controlled and those that are not controlled, and any unusual conditions. Here is an example of a section of that type.
