A control can either provide a baseline, show that the experiment is specific for the variable or show that the experimental procedure works.
So if you want to determine if having more enzyme degrades sugar faster you include a control that you know will degrade sugar at a certain rate. Then you compare what happens in the control and in your sample with more enzyme you can see if your hypothesis is correct.
When multiplying DNA by PCR one often uses a negative control (an organism without the gene and/or water) to show that you only multiply what you think you are multiplying and a positive control (a previously isolated piece of the DNA) to show that the PCR was successful even if none of the other samples amplified a fragment.

When conducting an experiment scientist should?

What is one way a scientist reject a experiment?
It can be rejected if there is no control variable.
What do scientist use to collect data for an experiment?
Set up an experiment and a control group, which has an independent and a dependent group
To eliminate the possibility of hidden or unknown variables the scientist must run what kind of experiment?
To eliminate the possibility of hidden or unknown variables the scientist must a control experiment.

What is the variable scientist actively change in an experiment?
control variable
Why is is it important that an experiment include a control group?
a control group assures that an experiment will be repeatable

Why do scientist use control groups in experiments?
Because it helps them know the results of the objects in the experiment and how they differ. This way the scientist knows which succeeded and which failed.
Whats one thing a scientist can do to help prove that an idea is true is do a experiment?
use a control
A scientist compares data from her control group and experimental group. What scientific method is she performing?
Observing an experiment
How can scientist test a hypothesis if it is not possible to do a controlled experiment?
If they can't do a controlled experiment chances are they're advanced and know what they're doing. Depending on the experiment itself, the scientist would have to come up with a procedure that doesn't involve a control. Although there may be no official control, they probably still compare the results to something.
What describes the independent variable?
The variable is an experiment that is manipulated by the scientist. APEX
