THE LABORATORY NOTEBOOK
Chemistry is an experimental science. As such, much of the progress of chemistry depends on the communication of
scientific data and experimental results between researchers. It is important, therefore, that a course in chemistry
should teach how to accurately record scientific data and experimental results through the use of the laboratory
notebook and laboratory reports.
THE LABORATORY NOTEBOOK
The laboratory notebook is meant to be a permanent record of the experimental data and observations that one
measures or observes during experiments.
During the laboratory period all data and observations are to be recorded
into the laboratory notebook and
on separate sheets of paper nor the data pages of the experiment
or laboratory manual.
The laboratory notebook is meant to be used as a

It will contain both
satisfactory and unsatisfactory results, errors and corrections, calculations, graphs, and other information from the
Since all entries are made in the laboratory, it is expected that the information be orderly,
legible, and clearly labeled, sufficient so that the information is comprehensible to someone with training comparable
to your own.
The notebook will not be graded on its appearance, it will be graded mainly on its content.
The laboratory notebook must be a
book with sewn-in pages and a cover, such as a "Composition Book" or
Spiral, loose-leaf, and perfect binding (pasted-in pages) notebooks are

The suggested guidelines for keeping the laboratory notebook
are listed below:
Your laboratory instructor may request that the information you record in your laboratory
notebook differs from this format to fit the requirements for your particular laboratory course.)
SUGGESTED RULES FOR KEEPING THE LABORATORY NOTEBOOK
All entries must be made in
All pages in the notebook must be numbered consecutively, beginning with the first page.
The first two sheets (pages 1 through 4) reserved for a
TABLE OF CONTENTS
, which must be kept up
to date with the number of the experiment (number them consecutively), the title of the experiment, and
the notebook page on which it begins.
When recording information in the notebook, write on the
only (unless a double
page is needed for a large table or graph).
Generally, the left-hand pages are used for notes or
calculations for the experiment.
