You need a control for any experiment. It doesn't sound like this particular experiment is of the utmost importance but it's a good habit to get into if you plan more important ones. I have no idea what the control would be.
Gives you a more correct method of predicting which is the right one.
list some variables that can change in an experiment?
a control is something that stays the same in an experiment
control means to take conrol in a science experiment
it is called the control of the experiment
The control of an experiment is the part of an experiment that does not change, and is strictly used as a comparison to the variable that is being tested.
The standard for comparison in a experiment is known as a control variable. This is useful to any experiment and serves as a reference point used to draw conclusions.
The control is the part of the experiment where it remains constant, and never changes. The control is used so the changing variable in the experiment can be reflected off of the control, so thereby comparing the changing variable with the control (the variable that does not change) in the experiment. Without the control, the experiment is a waste.
a control group assures that an experiment will be repeatable
The control experiment allows a standard of comparison for the experimental group
