Science fairs are competitive events. A large portion of what individuals are judged upon is their ability to present their ideas and the results of their experiments to the judges through a written report. An excellent report can enhance your experiment. The discussion is the portion of that report where you can explain the results and significance of the experiment. Be sure to read through your specific science report guidelines and tailor it to the expectations for that assignment or fair.

Step 1

Interpret the results of your experiment. Discuss what is already known about the topic and describe what your findings contribute to the subject.

Step 2

Connect your findings back to the introduction and hypothesis. Did the data support your hypothesis? Why or why not? Remember, this is not where you introduce new material.

Step 3

Explain the process used to reach your conclusion. Why did you do certain things in your procedure? How did you decide on your variables? Why did you test the amount you choose to? Look at your procedure and think about the questions you would have if you wanted to recreate the experiment. Be exact and detailed in your explanation.

Step 4

Compare your data. Describe what the data mean to the reader. Be sure that your ideas and information flow logically and clearly. This is a section in which many readers can get lost, so be sure to present only one thought in each sentence.

Step 5

Relate your work to previous research on the subject. These references can be to your own work or that of other scientists. Describe how your research complements, or fits into, what work already has been done.

Step 6

Describe the changes you would make if you did the experiment again. Is there a variable you would change? Also, is there a way that your work could be extended? You also can identify or suggest further research that needs to be done to fill gaps in that particular subject, if warranted.
