  PRESENTATION OF THE REPORT

The lab report should cover the following topics:
  • Title & objectives of the experiment 
  • Theory
  • Apparatus, instruments & materials used
  • Experimental procedure
  • Data & Observations
  • Calculations & Results
  • Analysis of Results
  • Conclusions


The content of each section is as follows:

Title & objectives of the experiment :

The title itself explains the purpose of the experiment. It should be as short as possible, but adequately describing the work done.
The objectives should clearly specify what is intended to study and the knowledge to be acquired. Should not be confused with a list of activities .

Theory

Reference is made ​​to the physical principles directly related to the experiment and to support the work done . It describes the formulas used, defines the symbols used. Should be supported in the bibliography, but should not be a copy of this text or a sequence of paragraphs copied without relationship.

Apparatus, instruments & materials used

A description of the equipment with which they worked and the instruments used. Schemes should be included and should describe the function of each instrument. Where possible, indicate the accuracy of the equipment. Not be limited to a simple list of instruments.

Experimental procedure

Enunciated each step carried out in the experiment, in the order of execution and a clear, so that the reader could play in as nearly as possible the experiment.

Data & Observations

The values ​​measured in the laboratory must be organized in a table. This table must be completed in the laboratory during or immediately after the experiment. The data collected should be analyzed and compared at the moment, in order to verify their coherence and correspondence. The nomenclature used should be explained and be consistent with that used in the theory. Besides the data, must be made annotations on the phenomena observed in practice and which are not necessarily measured.

Calculations & Results

The calculations performed to process the data and the results obtained are presented in an orderly fashion (possibly tabulated). If the calculations are repeated, there may be a calculation model and then a table with all the results. According to the phenomenon studied, the graphs can be useful for calculations and get results. Sometimes and for clarity, the data are re-presented in the table of calculations and results. Some people prefer to file joint data, calculations and results. In this case it should be noted on an appropriate form which of the variables correspond to values ​​taken in the laboratory and which of them are obtained in the calculation process.

Analysis

Any relationship that may exist between the variables measured, should be displayed in a graph. The measured values ​​should be placed in the graph and must be drawn on it a fitting curve found with a mathematical analysis, which should be included. If the purpose of the experiment is to evaluate certain constants or coefficients, make a comparison between the experimental data found in the laboratory and those entered in books or catalogs. If the experiment is to test a theoretical relationship, make a comparison between theoretical and experimental results.

Conclusions
Must present a complete analysis of the relationships between variables, comparisons between the experimental results and the theoretical concepts and the development of the experiment. The results presented discrepancies should be discussed, and possible sources of error, proposing ideas to help improve the performance and working procedure. In a way, this is to make inferences from the analysis of results.

Bibliography
Please specify all texts, teacher's notes, work mates, manuals, catalogs, etc.. That have been used in the completion of the report. For more details about custom lab report visit us to get quality service
