Lab Report Format

Writing Laboratory Reports in Science Classes

Lab reports, like any other writing, have their own format and style.  Their purpose is to communicate exactly what occurred in an experiment or observation and to clearly discuss the results.  The essence of a scientific experiment is that it must be repeatable.  Other students should be able to read your report, do the experiment following your description, and get the same or similar results. If they can’t, your report isn’t good enough.

USE THE REQUIRED FORMAT:            Lab reports have a standard form to make them easy to follow and read. No one, in college or on the job, has time to puzzle out non-standard organization. Use the format provided by your teacher.

WRITE LIKE A PROFESSIONAL:              Avoid personal pronouns such as “I” and “you.” Be clear and concise. Proofread, and correct errors. Make reports neat and clean. Labs should be written in blue or black ink or may be typed.  Do not use white out on a lab report.  Neatly line out any mistakes.

DO YOUR OWN WORK: While lab partners will have identical data, the analysis and conclusion sections must be done INDEPENDENTLY.  Students with identical or near identical lab reports will both receive zeros.

 

BASIC LAB REPORT FORMAT

TITLE	Include name of experiment, your name, class, instructor name, & date.
PURPOSE	State the problem to be solved or the experiment to be performed.  Explain the purpose and any necessary background.  You may use the purpose on your teacher supplied lab instructions.
MATERIALS or EQUIPMENT	Make a complete, accurate, neatly organized list of all supplies and equipment used.
PROCEDURE	Describe all the steps in the procedure.  When the teacher supplies a procedure, SUMMARIZE the steps so that someone familiar with proper lab procedure will understand and be able to repeat what you did.
DATA	Clearly record the results you obtained. Data should be displayed in neat tables and include the appropriate unit(s).
ANALYSIS OF DATA	Graph data if required.  Use SULTAN.  Make sure you label x-axis and y-axis with units.
DISCUSSION/ CONCLUSION	Explain your results. Evaluate what happened based on the claim/hypothesis and purpose of the experiment. This often entails the answering of conclusion questions.  Make sure that you answer these questions with complete sentences such that someone without the handout would know what the question was.  Avoid pronouns. If the results contained errors, analyze the reason(s) for the errors. The discussion shows how well you understand the procedures used and the processes that occurred.  This will be the longest section of the report.
