The Scientific Method

The scientific method is the only scientific way accepted to back up a theory or idea. This is the method on which all research projects should be based. The Scientific Method is used by researchers to support or disprove a theory.

The Scientific Method The Scientific Method involves 5 steps: Observation Question Hypothesis Method Result

The Scientific Method Observation- You observe something in the material world, using your senses or machines which are basically extensions of those senses. AH—Look at this!

The Scientific Method Question- You ask a question about what you observe. State the problem or question.

The Scientific Method Hypothesis- You predict what you think the answer to your question might be.

The Scientific Method Method - You figure out a way to test whether the hypothesis is correct. The outcome must be measurable (quantifiable). Record and analyze data.

The Scientific Method Result- You do the experiment using the method you came up with and record the results. You repeat the experiment to confirm your results by retesting.

The Scientific Method State Conclusion- You state whether your prediction was confirmed or not and try to explain your results.

Science experiments use…? Independent Variable Dependent Variable Controls/Constants

Scientific Vocabulary Experimental Controls or Constants: Something that does not change- all the factors that stay the same in an experiment.

Scientific Vocabulary  Variables: Something that is changed  Independent: The one factor that is changed by the person doing the experiment  Dependent: The factor which is measured in the experiment.
