Want this question answered?
A manipulated variable is the thing that can be changed in an experiment. example; your trying to see what paper towel would be more absorbant, your manipulated viariable would be either the type of paper towel you use or the liquid you use to test the absorbancy.
an experiment that can be controlled i did not know this That is not a good answer! A controlled experiment is: If you set up an experiment: Example: You have two plants. You want to know if fertilizing every day causes it to grow more. In your experiment everything has to be the same! Except one thing. You have to have the same type of dirt and pot and flower/vegetable. You have to water each of them every day. But, you fertilize ONE of them once a day until your results are clear to you, or when you want to stop testing. This way, you can see how the fertilizer effects the plant growth compared to just water every day. If you change more than one thing, like how much you water the plant, it is not a controlled experiment anymore. because then you won't know which variable (thing that you have changed) is taking effect. You wouldn't know if it was more water or the fertilizer, or both that is making the plant grow faster!
Environmental factors if you cannot control them.Variable factors if you can control them.See link below for easy explanation:In an experiment the scientist is able to change the independent variable. To insure a fair test, a good experiment has only one independent variable. As the scientist changes the independent variable, he or she observes what happens. - See more at: http://www.chacha.com/question/what-part-of-an-experiment-is-the-factor-that-you-change#sthash.iyH25Jac.dpufIn an experiment the scientist is able to change the independent variable.

In a science experiment, the independent variable is the one you change. For example: if you are doing an experiment on the impact of different types of soil on plant growth, the different types of soil would be your independent variable. The dependent variable is the outcome, or whatever the independent variable directly impacts. In this case, the dependent variable is the height of each plant.
It would be pointless doing the experiment and not measuring accurately
a controlled experiment must have only one manipulated variable becuase if the experiment had multiple manipulated variables then it would not be a controlled experiment anymore it would be a manipulated Deseret experiment
Well, when something changes, you would not know which variable caused the change in the experiment.
there is only one manipulated varable in an experiment otherwise it would not be a controlled experiment
The experiment consisted of copper pennies, 5 small beakers, and dropper bottles of: dish soap, water, ethanol, and baby oil. We had to drop these liquids onto pennies and see which could hold the most. So, what would be the manipulated, responding, and controlled variables in this experiment?
You need to describe the experiment; how else can anyone know what is being manipulated?
Controlling Variables are the variables that stay the same.The Manipulated Variable is the variable that you changed on purpose. There can only be one manipulated variable.The Responding Variable is the variable that was changed due to the experiment. For example, if you were testing how fast ice melts with differet materials, the responding variable would be the time it took for the ice to melt. Again, there can only be one responding variable.

A dependent (responding) variable is a condition that can change as the result of an independent variable's alteration. It can also be referred to as an effect. Every well-designed experiment has three kinds of variables. 1) Control variables, which are the same for each stage of the experiment. 2) Independent (manipulated) variables, which represent what is being changed by experimenters. 3) Dependent (responding) variables, which respond to the change and ideally are the direct result of the change in the independent (manipulated) variables.
the experiment result would be confusing
In an experiment, the manipulated variable is also known as the independent variable. An example of the term "manipulated variable" in a sentence would be, "The scientist sincerely hoped that the manipulated variable would produce a reaction in the dependent variable."
. Constant variables are variables which cannot be changed with the experiment. To remember their name is easy just think about Constance. They are important to an experiment because without all three variables there would be no complete experiment. Also the constant variables are important to an experiment because they help complete the result. Without a constant variable you. Would not be testing correctly
