In a properly structured lab report essay, the discussion can be used to establish the ending of the experiment before the conclusion. This is the component where you analyse and interpret the findings in the result against the proposed hypothesis and the facts about the subject matter you already had. A lot of the discussion is composed of the content covered in the Results, and one must know how to write the discussion in a way that supports their argument. A few key things should be considered in how to display discussion part.
The discussion can be way of expanding on the introduction, as in attempting to answer the questions that were posed or implied in there and discussing how the results reflect on the hypothesis. This is where you take your time clearly and comprehensively explaining how the acquired results give us a new perspective or approach to the problem in question. How your results have been similar or different from similar experiments conducted previously and what should be the next step. This is also a good opportunity to touch upon the negative results and their possible causes.
It is encouraged to use the active voice when figuring out how to display the discussion part. Even though the discussion should be through, it should not be redundant or repetitive. When making your points, be clear about your subject of discussion and do not stray from the topic. It is best when interpreting the results, to do them in the order stated in the Results and to avoid having to state them over and over again.
Discussion: Interpreting the results of the lab
1- State whether the results from the lab procedure support your hypothesis.
2- Identify specific data from your lab that led you to either support or reject your hypothesis. Refer to the visual representations of your data as evidence to back up your judgment about the hypothesis.
3- Using your understanding of the scientific concept of this lab, explain why the results did or did not support your hypothesis.
4- Additional discussion: (1) problems or sources of uncertainty in lab procedure; (2) how your findings compare to other students’; (3) suggestions for improving the lab.
Tips on writing the Discussion
- 1-It is not considered a failure if your data does not support your hypothesis. Failure to support hypotheses is common in science.
- 2-Back up the statement about the hypothesis with direct evidence from the lab data that supports, does not support, or partially supports the hypothesis.
- 3-Experimental science is about testing hypotheses. You, as a scientist, must be unbiased and objective.
- 4Do not introduce any new findings that are not presented in the Results.
- 5-Do not put detailed analysis of graphs, tables, and drawings in the discussion. The analysis belongs is Results.
- 6-Use the past tense when referring to what has been done in the experiment, but use present tense when talking about most everything else, such as scientific concepts, explanations, and references to articles.
