What dose variable mean in science?
A variable is an element in an experiment that you control. There should only be one variable in an experiment or the results will not be accurate.
When conductting an experiment a scientist should?
Attempt to control the conditions
When conducting an experiment scientist should?
Attempt to control the conditions
A part of an experiment to which you can compare the results of other tests?
Control
True or false. the control subject of an experiment be exposed to all variables?
False. The control subject (Or control group) should be kept isolated from the variables of the experiment. This group will detemine if changing a variable is better or worse than not changing the variable.

How many types of variable should be control in an experiment?
Ideally you control all variables except for the variable of interest.

A part of an experiment to which you can compare the results of other tests?
Control
Why should you have only one variable and as many control as possible in an experiment?
What a stupid question. Because you should.
What should you include in your experiment Scientific method?
You should include answer to your problem, 1 variable, and a control group.
True or false. the control subject of an experiment be exposed to all variables?
False. The control subject (Or control group) should be kept isolated from the variables of the experiment. This group will detemine if changing a variable is better or worse than not changing the variable.
What is a control variable in a science project?
It is the variables you will not change to keep the experiment a fair test, they should be kept constant to show how your independent variable affects your dependant variable.
What is the control in an expiriment?
The control is the subject in an experiment not introduced to the dependent variable. For instance if you were to test the effect of different types of fertilizer on plants, the control would be the plant with no fertilizer.
What is the differnce between a variable and control in an experiment?
the variable is allowed to change, the control must stay the same. If you are testing whether a bird whistles best in hot or cold temperatures, the type of bird should be the control.
What does independent variable and dependent variable mean?
The independent variable is the variable that the scientist controls and can change in an experiment. There should be only one independent variable in an experiment; otherwise the cause-and-effect of the independent variable cannot be determined.The dependent variable is the variable that is affected by the independent variable.EXAMPLE:Students of the same age have been given different sleeping hours (the independent variable)The next day they are tested for their performance (the dependent variable).(Having students the same age is a third type of variable, called the constant variable or the control variable. It is deliberately kept the same to reduce any effects on the outcome.)
