Study Notes
Scientific Method Steps
- Step One: Make observations, articulate a problem, and research related topics to lay the foundation.
- Step Two: Formulate a hypothesis to explain the observations or problem, known as the research question.
- Step Three: Conduct experiments to test the research question and hypothesis, while collecting relevant data.
- Step Four: Analyze the collected data to draw conclusions on whether the hypothesis was proven or disproven.
Key Terms
- Hypothesis: A tentative explanation based on research, tested for validity against the research question.
- Experiment: Trials designed to validate or invalidate the hypothesis under controlled conditions.
- Independent Variable: The factor that is manipulated or tested in the experiment, compared against a control group.
- Dependent Variable: The measured response or outcome resulting from changes in the independent variable.
- Control Variables: Factors that could influence the experiment's outcome but are kept constant to ensure valid results.
- Data: Measurements collected to compare the independent variable against the control group, guiding conclusions.
- Conclusion: An analysis of the data that provides answers to the hypothesis or research question.
- Theory: A thoroughly tested and widely endorsed explanation for observable phenomena, subject to revision with new evidence.
