What is a Lab report?
A lab report in engineering is a formal document that summarizes and communicates the results of an experiment, project, or research conducted in the field of engineering. Its primary purpose is to convey the procedures, findings, analysis, and conclusions of the experiment to a targeted audience, which may include instructors, colleagues, or others in the engineering community. Lab reports in engineering are essential for several reasons:
- Documentation
- Lab reports serve as a comprehensive record of the experiment, providing a detailed account of what was done, how it was done, and the outcomes.
- Communication
- They enable engineers to communicate their findings, methodologies, and insights to others in a clear and standardized format.
- Evaluation
- In an educational setting, lab reports are often used by instructors to assess students’ understanding of engineering concepts, their ability to conduct experiments, and their skills in data analysis and interpretation.
- Research Contribution
- In research and professional settings, lab reports can contribute to the body of knowledge in engineering by documenting new discoveries, innovative solutions, or experimental data that can be referenced and built upon by other engineers.
In the next section, we will outline the different section of the report.
Sections of a Lab Report
The specific format and requirements for an engineering lab report may vary depending on the institution, course, or industry standards. Here is is a general breakdown of engineering lab reports:
- Title Page:
- Include the title of the lab experiment.
- Your name and the names of your lab partners.
- Date the lab was conducted.
- Course name and section.
- Instructor’s name.
- Abstract:
- A brief summary (usually 100-250 words) of the entire report.
- Include the purpose of the experiment, methods, key findings, and conclusions.
- Introduction:
- State the objective or purpose of the experiment.
- Provide relevant background information, including theoretical concepts and previous research.
- State the hypothesis or research question.
- Materials and methods:
- Describe the equipment and materials used.
- Outline the step-by-step procedure followed during the experiment (procedure).
- Include any safety precautions taken.
- Data and Results:
- Present your data in a clear and organized manner. Use tables, graphs, charts, and figures as needed.
- Label all figures and tables with descriptive titles and include units of measurement.
- Calculate and show any relevant calculations or equations.
- Discuss any uncertainties or errors in your measurements.
- Discussion:
- Interpret your data and discuss the significance of your findings.
- Relate your findings back to the hypothesis or research question.
- Compare your results to the expected outcomes or theoretical predictions.
- Address any unexpected results or discrepancies.
- Summarize the key findings and their implications.
- Discuss any limitations of the experiment and sources of error.
- Conclusion:
- State the main conclusions drawn from the experiment.
- Highlight the practical implications of your findings.
- Suggest areas for further research or improvements in the experimental design.
- References:
- Cite any sources or references used in your report, including textbooks, articles, or lab manuals.
- Follow a specific citation style (e.g., APA, IEEE, Chicago) as required by your instructor.
- Appendices (if necessary):
- Include any additional information such as raw data, calculations, or detailed experimental procedures.
- Label each appendix with a letter (e.g., Appendix A, Appendix B).
Remember to check with your instructor or department for any specific requirements or guidelines for lab reports in your engineering course, as these can vary.
For example, some institutions have an “analysis” section between the results and discussion section for result interpretation. Be careful to follow your institutions standard.
Breakdown of Each Report Section
Here is a thorough breakdown of each report section:
Section 1: Abstract
Abstract represents a summarized report of the complete project in a concise and informative
format. The abstract should cover what was done, a highlight of how the work was done, the most significant results obtained and application/usefulness of the work.
You can not summarise something you have not written so save writing the abstract for last after completing other sections of your report. The entire abstract of a project report should be written in a maximum of 350 words. The abstract should be one paragraph without indentations.
Section 2: Introduction
The introduction to an engineering lab report serves as the foundational framework for understanding the purpose and context of the experiment.
An effective introduction informs the reader about the experiment, and sets the stage for the subsequent sections of your engineering lab report. It should clearly convey the significance and objectives of your work and make the reader eager to explore your findings and analysis.
We can split introduction into 3 parts:
a) Background Information
The background information section of a lab report provides the reader with essential context and foundational knowledge related to the experiment or research. Start off with a broad introduction to your topic.
Next narrow down the introduction to talk more specifically about the topic you are investigating, and why the study you performed was so important.
Then gradually focus on the exact phenomenon that you are experimenting on.
This is known as the inverted triangle of introducing information
b) Hypothesis/Research Question
In this part, you simply state your hypothesis of the concept you are investigation. You are stating the question your experiment is trying to answer.
c) Aims and Objectives
Aims are brief statements that state the overall goal or purpose of a research, while objectives are specific statements that describe the steps or actions needed to achieve the aim.
Section 3: Materials and Methods
This section should be written with enough detail that anyone would be able to follow your procedures and repeat your experiment.
The materials and methods section of a lab report tends to be the simplest to write because the procedure is either described in your lab manual or you made notes about it as you carried out the investigation.
This section can be split into two subsections:
a) Materials Used
SImply list the materials and equipment used in the experiment. Adding a picture of the experiment setup and labels of the equipment will enhance this sub-section.
b) Procedure
The procedure is a detailed step-by-step description of the activities that were done in order to gather the information needed to achieve the purpose of the experiment.
This section should be written in continuous prose (as one paragraph). Ensure you give sufficient detail so that anyone can follow your instructions and reproduce your experiment.
This section, like the other parts of the work, should typically be written in the past tense without the use of the personal pronouns (I or us).
Section 4: Results
In this section, focus on showing the reader your findings. Don’t try to interpret the data or talk about why they are important. Save your interpretations for the Discussion/Conclusion section.
Use the Results section to summarize the findings of your study. This section should .
The results section focus on the major trends in the data you collected. It contains paragraphs that describe the results of your experiment. The details can be summarized in tables and/or graphs that will accompany the text. Tables organize the data while figures (i.e. graphs, pictures) illustrate the data.
Remember to number and label them properly (for example, if one figure follows another, the first will be “Figure 1” and the second will be “Figure 2,” however if a table follows a figure, the figure will be “Figure 1” and the table will be “Table 1”). Place these labels above the tables and below the figures.
It looks professional and can be useful to readers to include a quick explanation of the figure next to the number.
As you write, make references to your figures and tables. If possible, place a figure or table below the paragraph in which it is referenced. Write this section in the past tense.
Remember, the results section is purely for results. Include your data or observations, including graphed data and data that was subject to statistical analysis, exactly as they were recorded in your lab.
Section 5: Discussion
The Discussion section is where you interpret and analyze your results. Discuss the factors that led to the findings you made (what caused the results).
When linking your findings to your hypothesis do not use the words “proved” or “disproved”; instead, indicate whether the evidence supported or did not support your theory.
Connect your results to the information you already gathered in your Introduction section, and see how they compare and contrast. If there are additional the questions being asked in the lab manual, answer them here based on your results.
If there were any possible sources of error in your data, discuss them here. Also discuss the limitations of your experiment and give recomendations on how to improve your results.
You may also mention the need for future research or what your plans are for further pursuing this hypothesis.
The discussion section should be written in the present tense.
Section 6: Conclusions
You should summarise your report in the conclusion section. A conclusion typically consists of one 200–300 word in one paragraph. In this way a conclusion is very similar to an abstract, but with more emphasis on the results and discussion.
Do not introduces any new ideas or results in the conclusion. Rather, provide a concise summary of findings and interpretations which have already been presented in the sections prior.
When crafting a conclusion, you should:
- briefly restate the purpose of the experiment (i.e. the question it was seeking to answer)
- highlight your main findings (i.e. answers to your hypothesis/ research question)
- note the main limitations that are relevant to the interpretation of the results
- briefly summarise the experiment’s contributions to the field’s overall knowledge of the issue.
Section 7: References
The References section, sometimes called Works Cited, is where you will list all of the sources you used in researching your topic. Consult you institution on which referencing style you should use.
Consider using microsoft word’s automated reference table function for this part as it makes this process easy and fast.
