How to Write a Lab Report

 

A Lab Report consists of seven components: abstract, introduction, procedures, results, discussion, conclusion, and in some cases, references.

Abstract

The Abstract is a one or two paragraph, consice yet detailed summary of the report. It should contain these four elements:

  • the main objective of the study (the central question)
  • a brief statement of what was done (methods)
  • a brief statement of what was found (results)
  • a brief statement of what was concluded (discussion)

It is often easier to write the abstract once the other components of the lab report are written. 

Introduction

This section tells the reader why you did the experiment. Include background information that suggests why the topic is of interest and related findings. It should contan the following:

  • a description of the nature of the problem and a summary of relevant research - in this provide context and key terms so that the reader can understand the experiment
  • a statement of the purpose, scope and general method of investigation in the study - express the central question being asked
  • a description of the experiment, the research question and hypothesis

Procedures (Materials and Methods)

This section should describe all experimental procedures in detail. Guidelines for this section:

  • Explain the general type of scientific procedure used to study the problem
  • Describe materials, subjects and equipment used
  • Explain the steps taken in the experiment
  • Mathematical equations and statistical steps should be described

Results

The results section should present data collected from the experiment and summarise data with text, tables, and/or figures. Effective results:

  • results should be presented, including those that do not support the hypothesis.
  • statements made in text must be supported by results contained in figures and tables.

Discussion

The discussion section should explain the significance of the results and give detailed account of what happened in the experiment. If results cotained errors, analyze the reasons for the errors.

  • Summarize the important findings of observation
  • Describe patterns, principles and relationships for results
  • Explain how results relate to expectations, aggreements, contradictions or exceptions.
  • Suggest theoretical implications of results. Extend findings to other situations or other species. Give the big picture - do findings help us understand a broader topic?

Conclusion

A brief summary of what was done, how it was done, show the results and conclusions of the experiment.

References

List any works cited in the text of report.
