Scientists use a process called the Scientific Method to test out their ideas and beliefs. Variables are the things that change in an experiment. The Control Group is the group that doesn't change. The Hypothesis is the scientist's prediction of what will happen in the experiment.
The Scientific Method
Variable: Any factor that can change or be changed in an experiment. Control Group: A group of participants in an experiment that does not receive the treatment being tested. Hypothesis: A possible explanation for a phenomenon that can be tested through experimentation.
In a science experiment, which element is the most important?
- Control Group
In a scientific experiment, the control group is the group that is not exposed to the variable being tested. A hypothesis is a prediction of what the outcome of an experiment might be. Scientists sometimes conduct experiments with a double-blind control group, which means that neither the participants nor the scientists know which group is the control and which is the experimental group.
