figure it out yourself ,geez its not that hard.
the controlled variables are the factors that are kept constant during an experiment. if they are not kept constant then they may affect the outcome of the experiment. the manipulated variable is the factor that is different between the experiment and the control. the responding variable is the variable that is being measured in the experiment.
The factors which you change (vary) are called variables.
The independent variable is the factor in an investigation that the scientist is changing. The dependent variable is the factor which is measured. All other variables, factors which could affect the experiment, are controlled, or kept the same. For example, in an experiment to find out how light intensity affects bean plant growth, the independent variable would be the intensity of the light. The dependent variable would be the amount the plants grew. The controlled variables would be things like the temperature, the acidity of the soil, the amount of water given, the amount of CO2 in the air; in short, anything that could affect the results.
In an experiment examining the effects of fertilizer and soil on flower production, the independent variables would be the type or amount of fertilizer used and the type or quality of soil. These factors are manipulated to observe their impact on flower production, which would be the dependent variable. By altering these independent variables, researchers can assess how they influence the number or health of the flowers produced.
Among other factors, the answer will depend on: the variability of the response (dependent) variable, the cost (disbenefit) of making the wrong decision based on the outcome, the cost of conducting the experiment repeatedly.

A controlled experiment is one in which all variables except the one being tested are kept constant or controlled. This allows researchers to accurately measure the impact of the variable being tested on the outcome of the experiment. By controlling for other factors, researchers can isolate the effects of the specific variable they are interested in studying.
A controlled factor in an experiment is a variable that is kept constant or unchanged throughout the experiment. By controlling these factors, researchers can isolate the effect of the independent variable on the dependent variable. This helps ensure that any changes observed are due to the manipulated variable and not other factors.
A controlled experiment might be impossible if there are too many variables that cannot be controlled or if it is unethical or impractical to manipulate certain variables. Additionally, external factors outside of the researchers' control can also make it difficult to ensure a controlled environment for the experiment.
An experiment is called a controlled study because it involves manipulating variables under controlled conditions to isolate the effects of those variables on the outcome or results. By controlling other factors that could influence the results, researchers can more accurately determine the impact of the variables they are studying.
Constants are factors in an experiment that stay the same. This should not be confused with controls -- which is a standard used for comparison
In an experiment involving sugar water, the controlled variable would be the amount of sugar used in the solution. By keeping the amount of sugar constant while altering other factors, researchers can isolate the effect of sugar concentration on the outcome of the experiment.
Evaporation is not a controlled variable, as it is a natural phenomenon affected by various factors such as temperature, humidity, surface area, and air movement. In an experiment, researchers may try to control factors that influence evaporation to study its effects on other variables.
A controlled experiment is one in which a control group is closely monitored. In this way, the experiment can be much more accurate as more factors are accounted for.
