Experimental Design Terminology Mrs. Nielsen Chemistry
Experimental Design Terminology Scientific Method: A technique for investigating phenomena or acquiring new knowledge based on making observations and measuring evidence to support a conclusion
Experimental Design Terminology Control Group: The standard of comparison for checking or verifying the results of an experiment (the “Normal” condition)
Experimental Design Terminology Independent Variable: The variable that is manipulated or changed by the scientist * If I am the scientist, then I control this! (graphed on x-axis) Example: Length of Spaghetti Noodle
Experimental Design Terminology Dependent Variable: The measured result of changing the independent variable (graphed on y-axis) Example: Mass of Spaghetti Noodle
Experimental Design Terminology Constants (Controlled Variables) Conditions that are kept consistent throughout the experiment What were the constants in the spaghetti noodle activity?
