1. Follow a sensible format to keep your report neat and well-organized. A
preferred format is given below.
I. Abstract: Present a very brief statement of the
goal of the experiment and the main experimental technique employed. Pretend
you are writing up your findings for submission in a scientific journal, perhaps
a journal of undergraduate physics research. Do not begin with the phrase "The
purpose of this lab is to..." or the phrase "In this lab we...". Always include
a brief statement of the results obtained. The abstract should not exceed ~10
sentences, and may be as short as two sentences. The point of an abstract is
to give the would-be reader the most concise statement possible of what the
paper is about, so (s)he can decide if it is interesting enough to be worth
reading.
Example of a good abstract:
"The visible line spectrum of hydrogen was measured using a grating spectrometer
and a hydrogen gas discharge source. Lines were observed at wavelengths l
= 6565Å (red), l = 4343Å (blue-green), and
l = 4140Å (violet). The predicted line at l
= 4200Å (blue) was not observed, possibly because of its low intensity. The
wavelengths of the observed lines are in good agreement with the predictions
of Bohr's model."
Example of a bad abstract:
"The purpose of this lab is to learn how to use a grating spectrometer. We observed
some of the lines predicted in Bohr's model and obtained 5% error."
II. Procedure: Please describe only unusual or innovative
procedures followed in your experiment, not described in the lab handout. It
is not necessary to reiterate the procedure section from the handout.
III. Data: Present all raw data neatly, if possible
in chart or tabular form. Always give the units and take care that the number
of significant figures used is correct. Be sure each chart or data table is
given a good title, so it is clear what the data is referring to. When possible,
estimate the error in a measured quantity.
IV. Analysis: Present all calculations in full detail.
If a number of similar, repetitive calculations are done, only show one example.
Describe carefully each new equation introduced, and define each variable used.
(Do not, for instance, write v = vo + a t without defining what the symbols
v, vo, a, and t refer to).
V. Questions: Answer all questions concisely in well-written
sentences.
2. Lab partners can share data freely - but only with those actually
present in lab and participating in the data collection. If your lab
partner is absent for any reason, (s)he must come in and collect data independently.
Everyone is encouraged to work together on calculations and the questions. However,
your final report must be your own unique product written by yourself
in your own words, not by copying or editing your lab partner's words.
It is a violation of the honor code to share any portion of your report with
others, especially by email.
3. You should use appropriate computer software - Excel, Mathematica, or Kaleidagraph
- for any plots included in your lab report. All plots must have a title and
the axes labeled. Be sure axis labels make clear what is being plotted, and
in which units. See the lab instructor if you need help with graphing
software.
4. Lab reports should be above all clear and concise. The goal is to make the
report as brief as possible, while still presenting all your work
in an understandable fashion. Coping with this apparent paradox is key to
good scientific writing.
5. Please submit a typed (not hand-written) copy of your lab report by 4pm
Friday. Late reports will be penalized 20% per business day.
