The notebook must be an approved type with permanent binding and carbonless duplicate pages. Each student is required to keep an individual laboratory notebook. There are some compounds that are not permitted in schools in the UK, mainly because they are carcinogenic or explosive. This section must be filled in as the experiment proceeds; do not wait until after lab to try to remember what happened. 1975, 607) in which we utilized this observation. 1973, 872, as well as in his Ph. ) with discussion of what these data imply regarding success of the experiment including product yield and purity; spectroscopic and chromatographic data should be included in the discussion. The advantages of using units throughout include:
an awareness that equations are not merely symbols, but express relationships between physical quantities; an check on whether the equations used are in fact right, because of the in-built check on the units of the answer; a gradual awareness of what sort of magnitude of answer is reasonable in a given set of circumstances. Here is a simple titration example to show what I mean, easily extended to other types of calculation.
Blue ink fades more readily than black, and red is least fade-proof of all. click here for outline.

Additional information about writing the laboratory notebook:
Ideally, a notebook that is labeled “laboratory notebook” is preferable as it likely has been designed for this purpose. 1975, 607) in which we utilized this observation. The ability to lay out calculations in a comprehensible manner depends on
knowing what you are doing and NOT being reliant on rote formulae; realising that calculations need linking words and phrases to make them readable; a correct use of units throughout the calculation. The inside front cover is the Table of Contents. A well kept notebook provides a reliable reference for writing up materials .
Therefore it is important to start good habits that will make your notebook as efficient and accurate as possible. These will be necessary, for example, in the simple distillation/fractional distillation lab experiments, but is not required in the other labs performed later in the year when distillation is performed. As a general rule, it is a good idea to set aside several pages at the start of the notebook for use as a table of contents. However, if you have empty space at the bottom of a page do not begin a new day’s work there. I still haven’t found what I’m looking for. Original pages must not be torn out or added to the notebook for any reason.
It is a salutary lesson in recording detail. The Discussion of Results section must be written after the experiment is completed. Never mind the details of the chemistry – note that the small point about the solvent transfer, omitted in the report originally, makes all the difference to the experiment and its reproducibility. Science does not take place on the pages of textbooks or learned journals, but it is recorded there. Kanare2 offers many insights into how such rights may be protected, and I am indebted to his book for numerous things that I had not thought of. Pencil should not be used for anything. As a general rule, you can use any .
Could another scientist who is competent in your field pick up your notebook and repeat your work solely from the written description without additional explanation. The Discussion of Results section must be written after the experiment is completed. Be sure to consult your research advisor to determine what policies he/she may require in terms of notebook format. Do not trust to memory, even for a minute or so – someone talks to you, and that data’s forgotten. If you use some computer program to process and/or analyze your data, you should explain exactly how the data were processed. All are couched in plain language, with many vivid phrases of delightful spontaneity.
I cannot think of any calculation in the A level course that does so
The following is quoted in Kanare, p69. The initial notebook number each semester is 1; if additional notebooks are needed, the numbering should be increased consecutively (2, 3, etc). The record should be as detailed as possible. We had a similar experience with synthesis of ReOMe4 from ReCl5 (J. I am not responsible for your risk assessments. A descriptive title should appear at the top of the page together with the data on which the work is being done (be sure to include the year).
Such factors are very important and must be recorded
The whole point of a laboratory notebook is that it should say exactly what was done, and when; make clear who did it; enable someone else to do the same thing at some future date; be durable and verifiable. A fresh page is a challenge; rise to it. Get in the habit of identifying each day’s work in your table of contents the day you are doing the actual work. The observations you make and the data that you record will lead to the acceptance or rejection of your hypothesis, and will decide what future experiments may be done. (expt and theo) and base peak (expt))
IR (expt freq(s) in 1/cm with identified functional group(s))
NMR for all peaks listed in order from lowest to highest chemical shift
PMR chemical shift in ppm (#H, signal splitting, J in Hz)
CMR chemical shift in ppm (signal splitting from GATEDEC, J in Hz, D90 direction, D135 direction). 0 cm3
Thus concentration of sodium carbonate solution = 0. Discusses the vital aspects of how to make a proper and permanent record of research work. Everything that is directly relevant to your work.

It may be that you have detailed instructions already, in which case they can be written or pasted into the notebook. WRITING A LABORATORY NOTEBOOK For every experiment that you do in the lab this year, you will need to have the following basic. Standard practical exercises will have been assessed by teachers, but this does not remove the need for you to consider safety for your own experiments.
This must be the main thing – you are writing for someone else. Peter Day, ‘The Philosopher’s Tree: A Selection of Michael Faraday’s Writings’
Writing the Laboratory Notebook
The skill of writing the Laboratory Notebook – even the existence of such a Notebook – has probably fallen somewhat into disuse with the advent of the photocopied worksheet. 0588 mol dm-3 × 106 g mol-1 = 6. A good record gives confidence in the reproducibility of your work, aids others in building on your research. Yet it is a vital part of industrial and academic research, and indeed can in these activities be required in law to establish, for example, patent rights. Sir Geoffrey Wilkinson was at Imperial College, University of London, and co-author of Cotton and Wilkinson, a standard University inorganic text.
