The scientific method is a way to ask and answer scientific questions by making observations and doing experiments.

 

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 hypothesis, design, execute, and evaluate your experiment.

 

• The steps of the scientific method are to:

  • Ask a Question

  • Do Background Research

  • Construct a Hypothesis

  • Test Your Hypothesis by Doing an Experiment

  • Analyze Your Data and Draw a Conclusion

  • 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.

• While scientists study how nature works, engineers create new things, such as products, websites, environments, and experiences.

  • If your project involves creating or inventing something new, your project might better fit the steps of The Engineering Design Process.
