Parts of a lab
Give the big picture: do your findings help us understand a broader topic? Although the major part of scientific investigation takes place in the laboratory--connecting equipment together, repairing, obtaining supplies and samples, checking each apparatus for consistency, calibration, and finally data collection by running the experiment—a great deal of time is spent to present the results in a concise, objective, critical and conclusive format called laboratory report similar to research paper.
Earlier in this guide we discussed pre-lab research, which covers evaluating, organizing, and integrating research in your report.
Parts of a lab
What scientific concepts are you meant to be learning? Simply state what you know now for sure, as a result of the lab: Quick Conclusion Reference. Usually you will have discussed these in the introduction. Suppose that the outcome is not close to what you expected. Physical Measurements-phys , dr. Graphics need to be clear, easily read, and well labeled e. Methods Describe the steps you completed during your investigation. Suggest the theoretical implications of your results. Evaluate what happened, based on the hypothesis and purpose of the experiment. What has other research said about this problem? Mathematical equations and statistical tests should be described. What Should It Look Like? References A listing of published works you cited in the text of your paper listed by author or however the citation style you are using requires the citation to be listed.
Data Numerical data obtained from your procedure usually is presented as a table. This is also where you would discuss any mistakes you might have made while conducting the investigation.

In our experiment, some of the items indicated under each section may not be needed. Now that you have completed an experiment and have collected all of the necessary information in your lab notebook and any supplementary data from analytical instrucments, you need to write up your results in a lab report. Describe what additional research might resolve contradictions or explain exceptions. Mathematical equations and statistical tests should be described. Compare your results to similar investigations. Graphics need to be clear, easily read, and well labeled e. Reader will look for some reminder of the basic information relating to this particular area. Note on Verb Tense Introductions often create difficulties for students who struggle with keeping verb tenses straight.
Some guidelines to follow: Explain the general type of scientific procedure you used to study the problem. The independent variable is on the X-axis.
Explain any agreements, contradictions, or exceptions. Explain what you are proposing for certain obervations.

Analyze the strengths and limitations of your experimental design. Effective results sections include: All results should be presented, including those that do not support the hypothesis. The discussion should contain: Summarize the important findings of your observations. Was it avoidable? Although the water samples were received on 14 August , testing could not be started until 10 September If there were differences, how can you account for them? The independent variable is on the X-axis. There is no short list of instructions for writing a good laboratory report. It should contain these four elements: What the objectives of the study were the central question ; Brief statement of what was done Methods ; Brief statement of what was found Results ; Brief statement of what was concluded Discussion. These were determined using the Debye-Sherrer powder camera method of X-ray diffraction. Title: The title can usually draw attention of the reader to your work. Methods and Materials or Equipment can usually be a simple list, but make sure it is accurate and complete. Give the instrument uncertainties. Sections of a laboratory report: A laboratory report usually have several sections identified by titles. Physical Measurements-phys , dr.
