How To: Write a Formal Laboratory Report
The laboratory report is a formal report of the experiment performed. The report conveys what was done in a concise, organized and
easy to read fashion. It should be written in the past tense using the passive (3rd person neutral) voice. All in-lab modifications to the
procedure must be noted. The following sections should be clearly labeled and contain the appropriate information in paragraph style
(use of complete sentences: using correct grammar and sentence structure are required). Keep in mind, the lab report must be written
so that another competent peer can reproduce the experiment and compare the results with your published results.
Each laboratory report is worth a total of one hundred (100) points. Obtain the “Chemistry Lab Report Rubric” from Blackboard to be
used as a guide. Each section of the laboratory report is evaluated as follows:
Title Page (5 pt.): Required for submission (however please use the header function to place your name (last, first) on each page in
case the title page is separated). The title page must include the following information :
Title of experiment
Student name (First and Last)
Partners name (First and Last)
Course Title and Code
Instructor Name
Submission Date
Abstract (5 pt.): Summarizes the report. The abstract should not be longer than 250 words. The abstract contains a brief explanation
of the underlying principles being explored in the study. The purpose for doing the experiment or the hypothesis is clearly stated. The
key findings (results) of the experiment and major points of discussion (relating your findings to the big picture of science) are stated
as well. Finally the major conclusions which were drawn from the lab are included.
*NOTE: THE ABSTRACT SHOULD ALWAYS BE THE LAST SECTION ONE WRITES. IT IS A SUMMARY, WHICH
CANNOT BE DONE UNTIL ALL OF THE WORK OF THE EXPERIMENT AND THE WRITING OF OTHER SECTIONS IS
FINISHED.*
Introduction (20 pt.): This section contains the pertinent historical and theoretical material that is relevant to the experiment. This
sections should include a discussion of a current journal article* as it relates to the major focus of the lab report. Keep in mind your
audience and organize your thoughts in a logical fashion. The final paragraph in this section should be a brief description of the
current experiment as it pertains to the theory described. Include balanced chemical equations where applicable. If you use the course
textbook, journal articles, library resources, the laboratory manual or internet sites to gather information, you MUST reference your
sources at the end of your report. All references should be numbered. This section DOES NOT include procedures.
Procedure (15 pt.): This section is written in the past tense, 3rd person neutral. You may reference the lab manual (handout); however
you must include the actual values used in the experiments (weights, volumes etc.) along with any changes to the procedure that
differed from the manual. Do not just repeat the handout with your values or verbiage. Write in your own words and be precise.
Remember, you are writing this report so another student can repeat the experiment. This section DOES NOT include the result or
observations, only the procedure for conducting the experiment.
Data (20 pt.): This section of the report is usually dominated with figures, charts, graphs, plots and diagrams. All should be clearly
labeled and sample calculations and/or formulas should be provided. Each figure should be numbered and have a figure legend briefly
describing the figure. If the figure was taken from an outside source, it must be referenced properly. This section is only for data, it
DOES NOT contain interpretation nor opinion.
Results and Discussion (25 pt.): This is the most important section of the report and should be the bulk of the report. It demonstrates
your ability to understand and interpret the data you have collected. The data presented, the observations, graphs, etc. are to be
interpreted as it relates to the ideas and concepts in the introduction and compared with literature sources where necessary. Relate the
experimental results to the journal article and theory discussed in the introduction. Formulate an opinion as to the relevance of this
study. For example, if in theory a reaction generates a gas, do you observe bubbles? This section also addresses the yield and purity of
products and possible sources of error that may have influenced these results. Be specific in these discussions. For example, do not
write “possible sources of error include human error and equipment error”. Error is specific to the experiment you performed and
should be discussed in that context. If the yield is greater than 100% explain why.
Conclusions (5 pt.): This section summarizes the main ideas and results. It connects your report to the larger world of science. Did
your experiment add anything new, or justify a known principle or law?
References (5 pt.): *You must use at least one peer reviewed journal article that has been published within the past 5 years.
References should be numbered (labeled) according to use within the text. Refer to the Citing Reference Guide on the ChemLibGuide
under the Gwinnett Technical College Library page.
