Steps of the Scientific Method
Key Info
· The scientific method is a way to ask and answer scientific questions by making observations and doing experiments.
· The steps of the scientific method are to:
o Ask a Question
o Do Background Research
o Construct a Hypothesis
o Test Your Hypothesis by Doing an Experiment
o Analyze Your Data and Draw a Conclusion
o Communicate Your Results
· It is important for your experiment to be a fair test. A "fair test" occurs when you change only one factor (variable) and keep all other conditions the same.


Overview of the Scientific Method

The scientific method is a process for experimentation that is used to explore observations and answer questions. Scientists use the scientific method to search for cause and effect relationships in nature. In other words, they design an experiment so that changes to one item cause something else to vary in a predictable way.

Just as it does for a professional scientist, the scientific method will help you to focus your science fair project question, construct a hypothescientific_method.gifsis, design, execute, and evaluate your experiment.

1. Observation and description of a phenomenon or group of phenomena.
2. Formulation of an hypothesis to explain the phenomena. In physics, the hypothesis often takes the form of a causal mechanism or a mathematical relation.
3. Use of the hypothesis to predict the existence of other phenomena, or to predict quantitatively the results of new observations.
4. Performance of experimental tests of the predictions by several independent experimenters and properly performed experiments.
