68. EXPERIMENTING RESEARCH QUESTION Scientists design experiments to answer questions or solve problems. The research question guides what the scientist tests and is answered using data gathered through testing. The research question usually states the relationship between what is changed and what is observed.

90. Conclusion A conclusion is a summary of an experiment. Someone who reads only the conclusion section of your report should be able to understand what your experiment was about. The summary should give your results, describe what those findings mean, and suggest new questions that should be investigated. A good conclusion can be written by answering six questions: 1. What was the purpose of the experiment? 2. What were the major findings? 3. Was your hypothesis supported or not supported by the data? Or were your results inconclusive? 4. How did your findings compare with the results of others in your class, or with information in your textbook? 5. What possible explanations can you give for your results?
