  1. Aim:How is the scientific method used to design experiments? Do now: Observe the picture and make two observations about it Vocabulary: Scientific method, experiment,variables

  2. Scientific method

  3. Experiment Scientists use an experiment 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 change. These changing quantities are calledvariables. Three kinds of variables: independent, dependent, and controlled. Theindependent variable is the one that is changed by the scientist. A good experiment has only one independent variable. As the scientist changes the independent variable, he observes what happens to the dependent variable. Thus, the dependent variables are the results of the experiment. In a controlled experiment all quantities remain constant ans is used for comparison.
