Lab Report Guidelines

        Due dates for lab reports will be posted on the course web site and in the lab. Lab
reports are due at the beginning of the lab period on the posted date. Late lab reports will
be subject to a 10-point deduction for each day late. Requests for regrades of lab reports
must be made to the TA within one week of when the report is returned. Requests must
include valid reasons why you believe regarding is warranted.
        Lab reports must be typed or printed from computer. Computer labs are available
on the 2nd floor of Welch Hall and at other campus locations. The computers and printers
in the CH369L/369T labs are not to be used for the preparation of lab reports.
        Plagiarism on lab reports or any other form of academic dishonesty will not be
tolerated. Lab partners can confer on general aspects of data interpretation, but each
student must write his/her own lab report independently. Plagiarism also includes
copying text or figures verbatim from any published source, including web pages,
without proper attribution. Violations will be reported to the Dean of Students in
accordance with University policy. Policies and standards regarding academic
dishonesty can be found at the Student Judicial Services web site,

University of Texas Honor Code
The core values of The University of Texas at Austin are learning, discovery, freedom,
leadership, individual opportunity, and responsibility. Each member of the university is
expected to uphold these values through integrity, honesty, trust, fairness, and respect
toward peers and community.

    This course is listed as a Significant Writing Component course. As such, you will be
expected to write and turn in lab reports that conform to established guidelines for proper
writing, both general rules and specific ones for scientific writing. Your writing will be
expected to demonstrate the following proficiencies:

   1.   No run-ons, comma splices, or inappropriate fragments.
   2.   A lean, efficient style.
   3.   No offensive or inappropriate language.
   4.   No subject/verb agreement errors.
   5.   No pronoun agreement errors.
   6.   No pronoun reference problems.
   7.   No misused, dangling, or misplaced modifiers.
   8.   Commas used correctly.
   9.   No spelling errors

Vocabulary used should be appropriate for a practicing scientist; appropriate technical
terms for equipment, reagents, measurement variables, etc. should be used. First-person
voice is acceptable provided the overall tone of the report is professional. The course
web site ( will link to some online
resources for scientific writers.
        In addition, your lab reports will be expected to follow the format given below.
Failure to do so will result in significant deductions from your grade on each lab report.

Lab Report Format

Introduction – 25%
     State a concise objective for the experiment
     Explain theory and methods directly applicable to the experiments done in the lab
     Identify any reagents, apparatus, etc., that are new to this experiment, and the
       reason for their use

Data and Observations – 25%
    Present all raw data in appropriate format
           Tables for numerical data (e.g., absorbance readings, pH values)
           Pictures of gels, blotted membranes, etc. with labels for lanes, bands, etc.
           Copies of instrument-printed data (e.g., spectra)
    Label all data appropriately
           Descriptive titles for tables
           Lane numbers for gel pictures
    Describe any observations made while performing the experiment
    Describe any procedural changes from the lab manual

Results and Discussion – 35%
    Report reduced data (calculated values derived from raw data)
    Present any graphs or plots of reduced data
            Include the individual data points, not just the curve
            For a linear regression, include equation and correlation coefficient (R2)
            Label all graphs and plots with title and axis units
    State and justify any conclusions reached from analysis of data
    Discuss probable sources of error (specific to each lab and based on your actual
       data and observations)
    Discuss specific topics listed in the lab manual at the end of each experiment

Appendix – 5%
    Show example calculations (typed)
    List literature references (including lecture notes) for any quoted text or figures
    Attach carbon or Xerox copies of lab notebook

Spelling/Grammar/Writing Style – 10%
    Use correct spelling and grammar (caution: spell check software does not always
       correct scientific terminology properly)
    Always use complete sentences and paragraphs (no bulleted lists)
    Reference any figures or text not made or written by you
    Write clearly and concisely
    Use an overall professional tone

Lecture quizzes

        There will be 4 quizzes given during the lecture portion of the course. Each quiz
will cover the material associated with 2-3 experiments, e.g., spectroscopy, buffers,
electrophoresis. Calculations and data analysis of a similar nature to those you have done
for your lab report may also be included. There will also be two short take-home
exercises assigned. Your quiz grades plus the take-home exercise grades will be
combined to give your lecture quiz average.


        Your evaluation grade will be assigned by the TA and Dr. McDonald based on
lecture and lab attendance and/or tardiness, lab technique, attitude, lab notebook keeping
and pre-lab quizzes. You are responsible for reading and understanding the lab procedure
and the lecture notes relevant to each lab exercise, and doing any preliminary calculations
and other notebook preparation, before coming to lab. Pre-lab quizzes may be given in
each lab section at various times to assure adequate preparation for lab. Points will be
deducted from your evaluation grade for the following reasons: Unexcused absences,

excessive tardiness, failure to follow lab manual procedure or TA instructions, improper
notebook keeping, failure to keep lab working areas clean and orderly.


        You must carry out a lab exercise to receive credit for it. Attendance at lecture
and lab is mandatory; absences will only be excused for documented medical or other
unavoidable reasons. Unexcused absence from either lecture or lab will result in loss of
points on your lab report and/or your evaluation grade. You will be expected to arrive in
lab at or before the scheduled starting time; tardiness will be penalized by deductions to
the evaluation grade. At the discretion of the TA, a student that is excessively late to a
lab session may be denied entry to the lab and required to make up that lab exercise at
another time.

Lab Notebooks

       You must turn in the carbon copies (or you can use a copier to make copies) with
your lab reports. Before each lab period you will be expected to prepare your notebook.
This includes stating a concise objective, and doing any calculations required for the
experiment. The TA will check lab notebooks during each lab. Note any changes to the
lab manual procedure and record data and observations. Proper notebook upkeep will be
a part of your evaluation grade; the lab notebook does not have to be pristine and
beautiful, but it must be organized and legible.
