Is this an experiment that relates substantively to PHY 111? (You can make the connection clear in your introduction.)
Are the independent, dependent, and control variables clear and appropriate?
Does the experiment actually address the hypothesis?
Was the experiment carried out with appropriate measurements and precision?
Is a thorough and accurate understanding of the relevant physics demonstrated?
Is the experiment original (we didn’t already do it in class and I can’t find it in existence already online)?
Is the conclusion appropriate and commensurate with the results?
Does the lab report follow the guidelines — both the format and the substance of each section?
