The Nature of Science

Scientific conclusions
When hypotheses have not been proven wrong despite extensive testing after a period of time and have formed the basis for other correct predictions, they are considered scientific theories
Scientific theories can never be 100% proven, like hypotheses, but if many people fail to find a result that contradicts the theory, it is considered reliable
-
Scientific experiments
Experiments usually have multiple types of subject groups and work by controlling all variables except one, the independent variable; the difference in results between groups will determine whether the independent variable has the predicted effect
-
The independent variable is a characteristic or phenomenon that is changed between subject groups and is the factor whose effects are being tested by the experiment
The control group is the subject group that experiences "normal" conditions by not being exposed to the independent variable
The dependent variable is the characteristic or phenomenon that is affected by the changes in the independent variable, and is observed to determine the results of the experiment

The Scientific Method
The scientific method is the process by which scientists make, test, and analyze hypotheses
-
Enables researchers to verify or disprove predictions and draw scientific conclusions in an efficient and falsifiable manner
