Match the description with the step of the Scientific Method The first step is when a scientist notices something worth of investigation Predication The scientist thinks about what should be studied. Question An educated explanation to the question being investigated before an experiment is conducted. Data analysis The expected outcome if the hypothesis explains well the phenomenon that is under investigation by the scientist: Experiment Active measurements of variables based on a design that test the hypothesis and its predictions_ Observation A summary of the experiment that is used to find patterns and to find if the hypothesis was supported by the experiment: Scientific Theory A final decision based on data analysis that determine if the hypothesis was supported or the scientist needs to step back and continue the investigation with a new hypothesis: Conclusion An explanation that explains multiple phenomena and has been broadly supported by scientists_ Hypothesis
