Why do experiments use controls?
what do you mean controls? I can best explain through example. Let's say that you are sea sick. You take two remedies, an acupressure bracelet and 50 milligrams of meclizine. You quickly start to feel better, but which of the two factors made the difference? The bracelet? The meclizine? A combination of both? This is a small-scale example, but in the fields of science it becomes important to know what causes a certain affect. This is the reason that we use controls.-Akilae

What is a constant setup experimental setup control setup and an experimental variable?
Control SetupThe constant control set up is where you have every thing "normal" to use to compare your experimental set up with the variable to. This has no variables and is always constant. For example if you wanted to see if plants would grow faster watered with sugar water or plain tap water, your constant control set up would be the plant watered with plain water. Since this is the "normal" condition with no changes it is the control setup.Additionally there are two kinds of controls, positive and negative. Positive controls will have an indication or contain the specific substance that the test or instrument is used for. On the other hand, negative controls don't contain that specific substance or instrument. For example if you were testing the effects of aspirin on inflammation and you gave a group, 20 mgs of a placebo, that would be a negative control. Opposite to that would be a positive control, if you were testing the same thing and instead gave the group 20 mgs of the aspirin.Experimental SetupIn short the part of the experiment that contains the variable is called the experimental setup. This is identical to the control setup except in one way. One change is made to the set up, this change is called the variable. In the example of the plants watered with tap or sugar water, the experimental set up would be the plant watered in the sugar water. Since this is the setup an which you are testing this, it is called the experimental (think of the experimental setup as a test) setup.Experimental variableThe experimental variable is basically what you are changing between the control and experimental setups.In the example, your experimental variable would be what the plant is watered with. So in this case, it would be the sugar water.

Use adequate in a sentence?
Example sentence - He completed his homework with adequate effort.
How do you use experimental variable in a sentence?
Scientists try to control for experimental bias.An experimental bias often goes unrecognized if the student does not carefully consider sources of potential biases.A desire for a specific outcome is an experimental bias.
