A lab report is a document that summarizes the experimental results that were obtained during a laboratory experiment. It is an important part of the scientific method, as it allows researchers to share their findings with the broader scientific community and to document their work for future reference.
There are several steps that you should follow when writing a lab report:
Title: The title should be descriptive and concise, and should accurately reflect the content of the report.
Abstract: The abstract is a brief summary of the main points of the report. It should be no longer than a few hundred words, and should include a summary of the purpose of the experiment, the methods used, the results obtained, and the main conclusions reached.
Introduction: The introduction should provide a background to the experiment and explain the scientific context in which it was conducted. It should also state the research question or hypothesis that the experiment was designed to test.
Materials and methods: This section should describe the materials and equipment used in the experiment, as well as the procedures followed. It should be written in enough detail so that someone else could repeat the experiment using the information provided.
Results: The results section should present the data that were collected during the experiment, including any tables, graphs, or other visual aids. It should also include a brief summary of the main findings.
Discussion: The discussion should interpret the results of the experiment, and explain how they support or contradict the research question or hypothesis. It should also consider any limitations or potential sources of error in the experiment, and suggest areas for further research.
Conclusion: The conclusion should summarize the main points of the report and should restate the research question or hypothesis in the context of the results.
References: This section should list any sources that were cited in the report, using the appropriate citation style.
It is important to remember that a lab report should be written in a clear and concise manner, and should be organized in a logical manner. It should also be written in the past tense, as it describes work that has already been completed.
In addition to these general guidelines, there may be specific requirements for formatting and style that you need to follow, depending on the guidelines set by your instructor or the journal in which you are submitting the report. Be sure to check these requirements carefully before submitting your report.
By following these steps, you should be able to produce a clear and well-organized lab report that accurately communicates the results of your experiment.

Surely, you can try to make up something effective, however, do not overdo it. Once the experiment was performed, and the density of the unknown solid was obtained, by comparing the density of other known metals, we established that the identity of the unknown metal was Tin. If you found that one type of fertilizer caused the plants to grow more quickly, you would mention this in the discussion section.

Introduction is usually present-tense at the beginning, when the background information is being summarized, and past-tense when talking about the findings of a previous study, or when the hypothesis is being stated A cockroach does x. Here, you can only conclude - not present any new ideas. References New Jersey City University 2013. In the graph, the density was plotted against the concentration and a trend line was then drawn.
