Every lab report should end with a properly constructed conclusion. It should be written in the 3rd person, that is, words such as “I” and “we” must be avoided. The conclusion should contain four main elements.

  1. Data and results that of particular interest, either supporting or refuting the hypothesis should be cited. Be specific.
  2. Research the theory you are investigating in the experiment. Also, offer practical uses of, or real-world examples of the concepts identified.
  3. Analyze the error in your results. This naturally requires the investigator to have made careful observations during the experiment. Remember, in any measurement, error is inherent. Error in calculations, or human error, especially misuse of a ruler, timer, protractor or other measuring device is NOT reasonable error.
  4. Offer educated follow-up to the experiment. What ways can the error be reduced? Stating that the investigator be more careful is NOT valid. My immediate question is why were you not careful in the first place. There are numerous ways to approach a problem; I want you to explore. Be creative.
