When doing an experiment, what is the difference between a control group & an experimental group?

Please give an example.|||Your control group is the thing you do not change.


The experimental group is the thing that you do change.





For example, if you are testing how sunlight affects plants your control group would be a plan getting the necessary sunlight to grow.


Your experimental group would be a plant getting too much sunlight, or a plant that does not get any sunlight at all.
