FORMAL LABORATORY REPORT FORMAT
In this course, you will be asked to submit three formal laboratory reports. The format described below is recommended, because it conforms to the range of methods widely used in scientific and Electrical Engineering journals. It is important to keep in mind that your goal is to present the information as clearly, completely, and also just as importantly, as concisely as possible. If you choose not to use this format, you should have a good reason to do so.
As always, you should write in grammatically correct, complete sentences. I recommend the use of the passive voice, as it is more formal and more widely used at least in my field, though it will not affect your grade if you do not choose to take this last recommendation.
The format for the formal laboratory report consists of 9 sections. Each group will submit a single report, using this format, for each experiment that requires a formal report.
1. Title Page
This page should include the course title, the department/course number, the date, and the names of the students who performed the lab and wrote the report.
The abstract is a very concise summary of the experiment and the results obtained. It is usually a single paragraph (just a few sentences) long, though in some cases, it may be somewhat longer.
The introduction serves to set up the reader for the rest of the report. It includes background information, as well as a description of how this work fits into the broader/wider contexts of the class, field, discipline, etc. It sometimes includes a description of the principles that underlie the experiment, but the details of the work usually fit better into later sections.
This section is used to present and/or derive any equations that will be needed to understand the experiment or perform the data analysis.
In this section, the details of the way the experiment was performed, how the equipment was configured, the way the data was collected, etc., are described. In Engineering 11, students have permission to refer to the lab handout if it is included as an Appendix to the report. There is no need to simply restate what is already written in the handout, but it is important to include deviations from the suggested methods. It is important to use the appropriate citations when referring to handouts or other materials.
Include both results, as well as sample calculations when appropriate.
- Make sure results are clearly labeled and set off from the text somehow (eg, in a table or graph), and not simply imbedded in the text.
- Think carefully about whether the information is better presented in a table, a graph, or both. (It is not usually necessary to present the same information in both a graph and a table, though it can occasionally be helpful.)
- Show experimental and theoretical results side by side for easy comparison, e.g. in the same table or graph. In tables, include the percentage deviations of the experimental results from the theoretical predictions. This is important!
This section is used to demonstrate the significance of the results, and to explain why they are or are not consistent with those that would be expected from theory and analysis.
- Discuss the significance, or meaning, of the results.
- Discuss discrepancies between theoretical and experimental results, and their likely causes.
- Discuss any difficulties encountered in performing the laboratory.
- Suggest changes that could be used to improve the lab. These may be included in the labs for future generations.
8. Conclusions and Future Work
The purpose of this section is to wrap up the lab and summarize what was reported. It is also a great place to make suggestions for future improvements. (I always appreciate such suggestions.)
The purpose of this section is to acknowledge any collaboration or help that was received during the experiments or writing of the report. I would also like you to include attributions for who wrote which section of the lab. More than one name per section is acceptable if appropriate. Please also indicate if there was a part of the lab that was performed by a subset of the lab group. For instance, if someone leaves early, and the other person/people finish(es) the lab, that should be indicated. Another example that should be described is that if some part of a lab is repeated to obtain better results, and not all partners can be present, the report should provide this information. (Being missing from one or a few portions of the semester’s experiments is not a problem since we all have occasional conflicts, but a persistent pattern of being absent is obviously not recommended).
Appendices can be used as sections for very detailed or lengthy sections of information. Information placed in an Appendix is usually supplementary to, or supportive of the discussion in the body of the report, but I usually not the most critical to the main points being made in the report.
Be sure that each table and graph is labeled (with a title and/or caption), numbered, and referenced in the text. Do not include tables or graphs unless there is at least a sentence or two (and often there is much more explanation needed) in the text so that the reader knows why the information has been included and what it has to do with the discussion at that place in the report.
