In this purest form, a laboratory report is a research-oriented document,
meaning that it starts with a hypothesis or
theory that needs to be applied and tested under highly controlled conditions.
For example, suppose you are an astronauts engineer
hypothesizing that your new wind design could be used to generate
high lift at hypersonic speeds with increased flight stability.
To test that hypothesis in a laboratory you would need an apparatus.
In this case a hypersonic wind tunnel and the model of your wind design.
You would also need a procedure for
using that wind tunnel to test your wind design model.
You could then use the procedure to collect data from the wind tunnel test and
interpret the data to see whether your new wind design generated
higher lead with increased stability under hypersonic conditions.
Finally, you could assess whether their original hypothesis was supported and
if so probably recommend that more research be done.
This is an example of a laboratory report.
Introduction, start the introduction by briefly and
statically describing the purpose of the report.
Next, provide the reader with enough with enough information on the problem so
that he or she can understand what the report is about and
put the information that follows in the proper context.
Round out the introduction with a statement of the scope regarding what is
being tested and any significant limitations of these tests.
Specify limitations of your report.
That is what it will cover and what it will not cover.
For example, your report may be limited to technical performance of a device or
may not include analysis of costs or marketability.
