In a scientific experiment, the control group is not exposed to the independent - variable and serves as a standard for comparison to see the effect of the independent - variable on the experimental group. Constants are factors that remain the same throughout the experiment. A hypothesis is a proposed explanation, and a variable is a factor that can change.
