It is important to control variables in an experiment because?
in an experiment cantrolling variable is important as it helps to identify the limiting factors are present in the experiment, and also factor that do not necessarily affect the experiment.
What are the constants and control related to science?
A constant is the thing that stays the same. The control is the normal variable or the regular variable. The control will help, in a science experiment, to see if a new object works better than the regular one. The constants helps to keep the experiment fair.
What is the definition of control in science?
Control in science is something that can be used for comparison to determine the magnitude of an experimental effect. For example in a control group either nothing is done or a fake version of the experiment is performed to determine a "baseline". The results of the control experiment and the real experiment can be compared. This process helps eliminate the experimenter expectations effect, making the conclusions more objective. Note: controls are rarely needed outside the field of biology.
In a controlled experiment a scientist changes one variable in order to?
i received this information from wikipedia. http:/en.wikipedia.org/wiki/Experiment hope that helps :)
Why is a controlled experiment important to science?
A controlled experiment means that you try to keep all the variables that are involved in the experiment under control apart from the Dependent and the Independent variables to make sure that any results obtained from the experiment have been affected by the independent variable and not some other extraneous variable. It also ensures that the experiment would have high validity. That is, if the experiment has really measured what it was supposed to measure.

answer: compare a plant not given fertilizer to a plant given fertilizer..
What is a test experiment that is cntrolled?
It is a controlled experiment. Take for example if you wanted to see how well a fertilizer helps in making a plant grow. All variables must be controlled except for one - the amount of fertilizer added. So you must have a control. Just stick the same plant in some potting soil with no fertilizer and add the same amount of light, water, temperature, etc as the experimental plant except add fertilizer to the one you are testing. The one that has no fertilizer is the control. You must have one of these to compare the one that you added the fertilizer to so you can see if the fertilizer made any difference. Hope this helps.
What is the controlled experiment in a science experiment?
The control in a science experiment is the same thing as a constant. It is something that you keep the same the entire experiment. For example if you were testing how various locations affect temperature your constants would be the thermometer you used and the time for measuring the temperature. If you don't have a constant than your experiment results won't be accurate.

What is a control in an experiment?
The control is what you keep the same through the whole experiment. I'm doing an experiment for a science fair this yer and its: What things can remove permanent marker from fabric. my control would be, the amount of "stuff" i use and the type or marker. hope it helps ♥
What are controls within an experiment?
You're trying to find which fertilizer works best. So u have 3 different plants 2 of them have two different fertilizers and one just has soil. The one with soil is ur controlHope this helps
The part of an experiment that does not contain the variable is known as?
this group is called the control group. the one that changes is called the variable. as in, it can vary. :) hope this helps!
Does variable mean the same as result?
no a variable is anything that can change. a result is what you conclude after performing an experiment. example: ok let's say you want to test a new fertilizer you would most likely use two different plants in the same room using a different fertilizer for each plant. the variable would be the fertilizer and the result would be if the new fertilizer worked or not. hope this helps.
What type of fertilizer helps plants grow?
Nirogenous fertilizer like urea
What does nitrate fertilizer mean?
Its fertilizer with extra nitrogen added to it. The nitrogen helps the soil.

What do you call a standard for comparison that helps to ensure that the experimental result is caused by the condition being tested?
a factor that changes in an experiment from manipulation of the independent variable is the
