Your teacher has asked you to write a lab report that focuses on one or more sections of the standard lab report. This webpage is designed to help you write that report.

Your report will have one or more complete sections—the section or sections assigned to you—but it will also have very brief summaries for each of the other sections of the lab report. So your lab report will have all the sections—Introduction, Methods, Results, Discussion, Conclusion—but with only a sentence or two in the sections that were not assigned.

Directions for writing a partial lab report

  1. Be sure that you know which section or sections you were assigned to write in full.
  2. You may open a document and use the guide on this page for writing your lab report. As you are writing, create a heading for each section.
  3. Follow the order for writing lab reports the LabWrite way: Methods, Results, Introduction, Discussion, Conclusion, Abstract, Title, and References.
  4. For each section you are assigned to write in full, select that option, which will show you more guidance that leads you step by step through writing that section.
  5. After you have finished writing that section, resume the instructions to continue writing the rest of your report.
  6. For each section you are NOT assigned to write in full, just write a sentence or two summarizing that section (follow the directions in each section.)
  7. When you have finished all the sections, rearrange them in the proper order to turn in to your teacher: Title, Abstract, Introduction, Methods, Results, Discussion, Conclusion, and References (if it is assigned).

Methods

Describing the lab procedure

Select one:

Using your lab manual, handouts, and notes taken during the lab as a guide, describe in paragraph form the experimental procedure you followed. Be sure to include enough detail about the materials and methods you used so that someone else could repeat your procedure.

Write a sentence or two summarizing the procedure you followed for this lab.


Results

Making sense of your data for yourself and others

Select one:

Step 1: If you haven't already done so, put your lab data in visual form by creating appropriate tables, graphs, and other figures. Representing your data in a visual format will allow you to identify trends and relationships among variables more easily.

Step 2: Once you have generated visual representations of your data, decide the order in which your tables, graphs, or other figures should be presented in the Results section.

Step 3: Review all the data from your experiment. In a sentence or two, summarize the main finding of this lab. This is the opening sentence(s) of the Results section.

Step 4: In separate paragraphs, summarize the finding in each of your visuals--tables, graphs, or other figures. First state the overall relationship or interaction among variables that each visual represents. Then include any specific details from the visual that are important for understanding the results. Refer to your tables, graphs, or other figures as figure or table 1, 2, 3, etc.

Step 5: Complete the Results by placing all the elements you've written in the proper order: (1) the sentence summarizing the overall data for the lab; (2) the paragraphs of word descriptions for each visual arranged in the order the visuals are presented.

Write a sentence or two summarizing the overall findings of this lab.


Introduction

Establishing a context for the lab

Select one:

Select one:

Step 1: Revise your answer to PreLab question 1 in one or two paragraphs. Begin the Introduction with 1 or 2 sentences clearly stating what scientific concept the lab is about. Then use the rest of your answer to question 1 to complete the paragraph with information about the scientific concept. Revise your answer so that it includes only the information that relates specifically to this lab. If you have a lot of information, make two paragraphs. Note any citations you use here for including in the References section of your report.

Step 2: Revise your answers to PreLab questions 2 and 3. Write the main objectives of the lab in sentence form. Then complete the paragraph by describing how the achievement of these objectives helped you learn about the scientific concept of the lab.

Step 3: Revise your answers to PreLab questions 4 and 5 in a paragraph or two. First, state your hypothesis clearly (even if it was not supported by the data). Then rewrite the explanation for your hypothesis so that your reader understands how the reasoning behind your hypothesis is based on the scientific concept of the lab.

Step 1: Begin the Introduction with 1 or 2 sentences clearly stating what scientific concept the lab is about. Then finish the paragraph by writing down details about this concept relevant to the lab that you can find in the lab manual, textbook, class notes, handouts, etc . . . Revise your answer so that it includes only the information that relates specifically to this lab. If you have a lot of information, make two paragraphs. Note any citations you use here for including in the References section of your report.

Step 2: Write the main objectives of the lab--the specific actions you took in the lab, such as measure, analyze, test--in sentence form. Then complete the paragraph by describing how the achievement of these objectives helped you learn about the scientific concept of the lab.

Step 3: State your hypothesis, what you thought the outcome of the experiment would be before you did it. This will be the first sentence of the hypothesis paragraph. To write a scientific hypothesis, you first need to identify the independent and dependent variables in the experiment. Write or sketch your hypothesis, describing the relationship among the variables you listed.

Step 4: Continue the paragraph you began with a hypothesis by explaining how you used your understanding of the scientific concept of the lab to arrive at your hypothesis.

Write a sentence or two that (1) tells what scientific concept you are supposed to be learning about by doing the lab and (2) states your original hypothesis for the lab, that is, what you thought the results of the experiment would be.


Discussion

Interpreting the results of the lab

Select one:

Step 1: Write a sentence or two stating whether or not the results from the lab procedure fully support your hypothesis, do not support the hypothesis, or support the hypothesis but with certain exceptions.

Step 2: In a paragraph, identify specific data from your lab that led you to either support or reject your hypothesis. Refer to the visual representations of your data as evidence to back up your judgment about the hypothesis.

Step 3: In a paragraph, use your understanding of the scientific concept of this lab to explain why the results did or did not support your hypothesis. If the hypothesis from the Introduction was not fully supported, show how your understanding of the scientific concept has changed. Note any citations you use here for including in the Reference section of your report.

Step 4: Discuss other items as appropriate, such as (1) any problems that occurred or sources of uncertainty in your lab procedure that may account for any unexpected results; (2) how your findings compare to the findings of other students in the lab and an explanation for any differences; (3) suggestions for improving the lab.

Write a sentence saying whether or not your original hypothesis was supported by the results you found.


Conclusion

Focusing on what you learned by doing the lab

Select one:

Step 1: Write a paragraph summarizing what you have learned about the scientific concept or procedure of the lab. Back up your statement with details from your lab experience.

Step 2: If there is anything else you have learned about from doing the lab, such as the lab procedures or kinds of analyses you used, describe it in a paragraph or 2.

Write a sentence or two describing what you learned about the scientific concept of the lab by doing the lab.


Abstract

Summarizing the lab report

An abstract is a miniature version of the whole lab report. It typically consists of one-sentence summaries (sometimes two sentences) of each of the major sections of the report: Introduction, Methods, Results, Discussion, and Conclusion. These sentences are arranged in a block paragraph.

If you are asked to write only an abstract of your lab, follow the directions for each lab report section on this page starting with Methods, but for each section, write only the one-sentence option (not the complete section option). Then put your sentences together in a block paragraph in the proper order: Introduction, Methods, Results, Discussion, and Conclusion.


Title

Capturing the essence of the report

Give your lab report a title. A good title captures what is important about the lab, including the scientific concept the lab is about and variables involved, the procedure, or anything else that is useful for describing what this report is about.


References

Acknowledging sources of information

If you were asked to include the References in your report, put a References section at the end. List all the sources you referred to in writing the report, such as the lab manual, a textbook, a course packet, or scientific articles. Be sure to use the proper form of documentation for the scientific field you are working in (ask your lab instructor if you are not sure). See Citations and References
