Write the Purpose (This is a statement of the problem to be investigated. It provides the overall direction for laboratory
investigation and must be addressed in the conclusion.) , Apparatus ( All laboratory apparatus used in the investigation, along with
a detailed diagram to illustrate the configuration of the
apparatus, should be included in this section. See example at
right. The variables to be measured should be clearly
pictured.) ,Procedure (This section should identify and name all experimental variables and briefly describe how the
independent variables are controlled. Someone who was not present during the lab should be able to
understand how the experiment was performed by reading your procedure.), Data (Data consists only of those values measured directly from the experimental apparatus.
No values obtained by way of mathematical manipulations or interpretations of any kind may be included
in this section of the report. Data should consist of as many trials as judgement would indicate necessary.
The units for physical measurements (kg, m, s, etc.) in a data table should be specified in column heading
only.), Evaluation of Data (This section should include all graphs, analysis of graphs, and post laboratory calculations. In this
section you must answer the Analysis (section ANALYSIS in the handout) questions. State each
formula, and if necessary, identify the symbols used in the formula. If repetitive calculations are to be
performed, substitute only one set of data into each formula and then construct a table of values for all
additional calculated values. Be certain that your final calculated values are expressed to the correct
number of significant figures. Do not show your arithmetic calculations) and coclusion (In the conclusion you must do the following:
a) State the relationship between the variables identified in the purpose in a clear, concise English
sentence.
b) When a mathematical expression can be derived from graphical analysis, write it, making sure to
include the appropriate units. State the meaning of the slope and discuss the significance of the yintercept (when appropriate).
c) Describe any new terms that arise as a result of your evaluation of data.
d) When your results differ from what is expected, provide a plausible explanation.)
