Here is a helpful website that has a great example of a controlled experiment: http://scienceray.com/physics/controlled-experiment-example/?237567#comment-237567&reload
An experiment has to have a varible, if it doesn't that it's probably and engineering experiment or robotics. I think its called a "control"
Controlled (or control) variables are things that are kept the same during an experiment. There are usually many- for example, when testing how light intensity affects photosynthesis, the controlled variable would be the type of plant used, or the color of the light.
In an experiment, the independent variable is altered, and the effect observed is the dependent variable, or outcome. The controlled variable is intended to be kept the same throughout the experiment so that changes in it do not affect the results.
Basicly, it means a hypothesis or educated guess about the outcome or future ofsomething. Example: Tommy thinks he's going to get 50$ on his birthday. He predictshe's going to get 50$ on his birthday.

A prediction as to what will happen after something is performed. For example, before carrying on an experiment, you predict what will happen. Therefore, hypothesize.
Pretty much having controlled variables. Controlled variables are something in the experiment that must remain the same through all tests. For example, if you are testing the decay of an apple... The temperature that the two fruits are enduring during the experiment must be the exact same.

A controlled experiment is an experiment in which all factors are controlled except for the one variable you will be altering. If you were performing a controlled experiment on the effects of fertilizer on plant growth, for example, you have to control plant variety, exposure to sunlight, soil type and water ration. The only thing you would change is the fertilizer used on each plant.
For example - a business controlled and operated by a group of users for their own benefit
it depends the one you wish to control in the experiment , for example if the temperature was measured every minutes so the controlled variable is time...
It is an experiment in which only one variable is changed for example if I was seeing where a banana rotted fastest the only variable that would change is where the banana is placed.
A perfect example of how theories are tested ! Theory predicts the outcome of the experiment, and the purpose of the experiment is to test the theory. If the outcome of the experiment is appreciably different from the one predicted by the theory, (and if the experiment itself was valid), then the prediction is flawed, and the theory must be either tweaked or trashed.

Example: I predict that distilled water will make a plant grow faster than tap water. Do a 2-4 week experiment watering six plants (3 with distilled water and 3 with tap water) of the same species. Measure the growth every week in cm and compare it. IN the end you will find out if you prediction was correct or not. Hope this helps
