Be sure to secure loose papers in your lab notebook with glue, tape, or staples. Feedback and other contributions to the research effort can be integrated easily with the understanding that everything is donated to the public domain.
Your lab notebook will be a sequential record of your project, so the dates are important. In court, dates of invention, description of an invention, and research techniques can be established through carefully kept laboratory notebooks.
This includes study rationale, materials, methods, models, raw experimental data of all kinds, including incorrectly performed work, interpretations, calculations, conclusions, and proposed next steps. Corrections must be made by drawing a single line through the entry see Figure 3.
Your lab notebook should be used from the beginning of your project and should reflect all phases of your project and all steps of the scientific or engineering method.
However, if a procedure is unsuccessful you may want to check to see that you used the correct rpm or correct rotor. Signing in this way would clearly show, if at any time in the future the attachment had been removed. The difference is that rather than purchasing a laboratory notebook and writing in it, research activity is documented electronically.
You should not black out, erase, or cover up any data. Specific information can be more readily located that way. One microfilmed copy will be kept in the library for access at any time.
Corrections should be made by drawing a single line through the entry. Signing in this way would clearly show, if at any time in the future the attachment had been removed. Pads of tear-out graph paper or spiral bound notebooks without pre-numbered pages are not acceptable.
If your notebook does not include a prelabeled table of contents section, then reserve the next several pages for a table of contents by labeling the top of each page as Table of Contents and numbering each page. If your notebook does not have prenumbered pages, you may wish to use lower case Roman numerals, as in a standard publication.
However, once you carry out a procedure, you can refer to that part of your notebook, and only note changes you make. Even if a procedure is outlined in a paper or published laboratory manual, record all of your procedures the first time you do them.
Even if your entry is very short, adding a date helps you track when you took certain steps or made certain observations. The openness of the notebook, then, specifically refers to the set of the following points, or elements thereof: As you plan your science project, use your lab notebook to capture the questions you hope to investigate, your hypothesisand your variables.
What if you are conducting two long procedures at once, each with long waiting periods?
If a proper chronological record is kept and co-signed by a coworker or supervisior, it is a legally valid record. Record contents in chronological order. When making entries, do not skip pages. Some investigators prefer to attach such materials to the notebook itself, but too many such items make a sloppy notebook and can stress the binding.
When you add notes later or correct a mistake, always initial and date your comment. The entries are short, but each is dated, the observations are clear, and important data has been recorded in each entry.
Never erase or obliterate an entry. As you begin your experiment, document your steps, trials, and observations.
What to enter Above all, it is critical that you enter all procedures and data directly into your notebook in a timely manner, that is, while you are conducting the actual work.
Use each page in order. That is the only way you will be able to catch possible mistakes later, modify your procedures, or report exactly what you did. Unsecured items including sticky notes may fall out or be damaged.
As you gather databe careful to accurately enter all numbers, measurements, temperatures, calculations, or other data. Few students and not that many researchers for that matter record sufficiently detailed and organized information. In labs doing proprietary research confidential- such as industrial research for profit a properly maintained notebook is essential.
For example, suppose you are conducting a protein assay and preparing a gel for your samples out in the laboratory. The best option is a lockable bookcase, or cupboard, or a locking file cabinet. However in the notebook it is important to note who was responsible for what procedure. Record HOW each procedure is done, even such mundane procedures as pipetting, calibrating a spectophotometer, or finding cells in a microscope.The laboratory notebook forms a permanent record that can be referred to while completing a disclosure report (often the first step in patent preparation) and later, provides accurate documentation of.
Abstract. A laboratory notebook is an important tool that goes well beyond research management and can have important implications for issues ranging from intellectual property management to the prevention of fraud.
A laboratory notebook (colloq. lab notebook or lab book) is a primary record of research. Researchers use a lab notebook to document their hypotheses, experiments and initial analysis or interpretation of these experiments. Guidelines for Keeping a Laboratory Record We usually record a lot more information in a laboratory notebook than we would report in a research paper.
For example, in a published article we don't report centrifuge type, rpm, rotor type, or which machine was used. For a new laboratory study, write down a very brief introduction to the.
keeping a lab notebook including appropriate content for the notebook, how much detail you should include, and some of the ethical considerations in keeping a notebook. Finally, we will show some examples of what a good lab notebook looks like. Examples of Notebook Pages and Entries. Here are examples of a title page and specific notebook entries.
The work may be ancient history but as an example of recordkeeping this mateiral may be far more effective than general guidelines in delivering the message.Download
