Formulate the "Introduction" section of your report. In this portion, state your hypothesis and explain how you chose it. For instance, if you read a number of scientific journals before you decided upon your hypothesis, include that information. If your professor gave a lecture that got you thinking about a topic, that information is also relevant in this section. In addition, state the expected outcome of your hypothesis, even if it differs from the conclusion you will list later.
Detail your testing methods. In the "Methods" section, list not only the plans you made to test your hypothesis, but also the materials you decided to use. Include your reasoning for choosing these methods and materials. Cite previous studies that used similar methods if they were a determining factor in your choice.
List the results of your tests and studies in detail. In the "Results" section, include the raw data derived from your tests. Avoid making an interpretation during this section; just list the results. If you have access to charts or tables to illustrate your results, use them here. If you use illustrations, cite them within the corresponding text, such as, (See Chart 5A).
Follow with the "Discussion" portion. This is the conclusion you drew from the results of your tests and studies. Explain how you reached your interpretation based solely on the data. In addition, state whether the results support your hypothesis as you stated it in the Introduction. Be honest here, it matters less that you had an incorrect hypothesis than it does that you correctly reported the results and the conclusion.
Read and edit your science hypothesis report until every statement makes sense and there are no spelling or grammatical errors. Make sure you've included enough information to allow the reader to understand why you arrived at the conclusion you did.
