A cornerstone of scientific experimentation is that an experiment can be repeated by other investigators and the same results achieved. In order to make this possible, a written record of the experiment must be kept including the analysis of the data, observations, inferences and/or conclusions reached.

Anyone reading your lab report should be able to reconstruct your experiment precisely in its entirety. The outline for your report should follow the report outline given below.

When you are asked to write a report of an experiment in which the results and your interpretations are of primary importance, the procedure is usually outlined for you. PurposeBriefly state the reason for performing this experiment. In a concise phrase describe that goal which you hope to achieve by carrying out this experiment.

Example: Verify the law of conservation of energy. Hypothesis Describe the theory which will be tested during this experiment and predict what will happen. Procedure Carefully explain, in a step-by step fashion, what is done in this experiment.

This may be a narrative or a list of specific steps, but must instruct others to duplicate your procedure precisely.
