Build a traceable experimental record
A laboratory report should make it possible to understand what was measured, how it was measured, and how the numerical result follows from the record. Separate the measurement procedure from the theoretical model used to interpret it.
A useful report structure
- Question and model. State the physical question and the relation to be tested, defining every symbol and unit.
- Apparatus and method. Identify the instruments, relevant settings, measurement range, and procedure.
- Observations. Present the original data, including repeated readings and departures from the planned procedure.
- Analysis. Show calculations and graphs, label axes and units, and explain the treatment of uncertainty.
- Interpretation. Compare the result with the model without confusing a fitted parameter with an independent prediction.
- Limitations. State the sources of uncertainty and identify a useful improvement or additional test.
Read research in the same way
For a theoretical paper, ask which objects are defined, which assumptions are supplied, what is proved from them, and how the result is connected to an observable. These questions are particularly useful when comparing conceptual diagrams with mathematical models.
Safety and official instructions
Follow the laboratory’s approved safety rules, equipment instructions, and the supervising instructor’s directions. This general reading guide does not authorize an experimental procedure or replace local laboratory training.
