Purpose: The purpose of this lab is to ...
A brief
statement describing the main objective or goal of the experiment. Can copy
from lab handout.
Introduction:
Approximately 1-2 pages in length. Do not paraphrase or recopy the
introduction from the lab handout or other possible sources. Put in your own
words.
It should include theory relevant to the experiment. Not all relevant
theory is included in the lab handout. For example experiments that use acids
and bases should include basic acid-base theory in the introduction. The
description and basic operation of specialized equipment such as infrared
spectrometers or UV spectrometers used in experiments must also be included.
Reaction equations should also be included.
It should include definitions and formulae pertinent to the subject of
the lab. Only include formulas used in the actual calculations.
Procedure: Refer to lab handout (Title of Experiment).
Any changes
made to the experimental procedure must be included.
Data/Observations:
Data Table 1: Data
Table listing raw data. Raw data includes all data recorded during the actual
experiment. This would include all relevant masses weighed and recorded
volumes. All data must be properly labelled and include the appropriate
number of significant figures(SIG.FIGS.). |
Experimental
observations such as color changes and added reagents when observation noted.
Stated experimental trends. An example would be the increase in absorbance with
increasing concentration of reagent A.
DO NOT explain observations. Just state.
Experimental
plots must include a proper title and labelled axis and placed after the data
section but before discussion section of lab report. See attached plot as an
example.
Calculations:
For one
trial show one complete calculation with a brief statement describing the
calculation.
For
example:
The mass of
standard used is converted into moles.
Calculation 1
Moles of
standard is converted into moles of unknown using balanced equation.
Calculation 2
Moles of
unknown is converted into grams of unknown.
Calculation 3.
Data Table:2 Data
Table listing calculated data for all trials. Calculated
average and standard deviation(if requested). |
NOTE: Be sure
to label all amounts with proper number of significant figures and units.
Example:
25.00 mL of HCl.
Discussion:
Include a restatement of the objectives and whether or not they were
met. Discuss any experimental observations, such as the solution turned red
when reagent A added, and explain.
Discuss sources of error and explain how they would affect your results.
If the experiment didn’t produce the correct result discuss possible reasons.
Were any assumptions made?!
Discuss your results. The results are what you are looking for and are
stated in the purpose. For example if the purpose of the experiment was to
determine the concentration of iron in a solution then the final result should
be the concentration of iron. Compare your results with known values when
applicable.
Conclusion:
Restate the main objective of the experiment and give a brief statement
that
summarises
your results. If the purpose of the experiment is to determine K then the
average value determined from all trials should be stated with proper units, if
applicable. If the result is temperature sensitive be sure to include the
temperature at which it is recorded. If the purpose of the experiment is to
determine several variables then a table stating these variables can be used.
References:
Include any sources that were used to write the report, for example, textbooks or reference materials.
