∙ 10y agoA controlled experiment is when only one variable, the manipulated variable, is changed at a time to observe its effect on the dependent variable, while keeping all other variables constant. This approach helps to determine the specific impact of the manipulated variable on the outcome of the experiment.
An example of an experiment where only one variable is changed is testing the effect of different amounts of sunlight on plant growth. In this experiment, all other factors such as soil quality, water, and temperature are kept constant, while the amount of sunlight received by each plant is varied. This allows researchers to isolate the specific impact of sunlight exposure on plant growth.
A dependent variable is a factor in an experiment that is influenced by another factor. An example might help to clarify. You are performing an experiment in which you are observing how sunlight affects plant height. Plant height is the dependent variable because it is dependent upon how much sunlight the plant receives. Sunlight is an example of an independent variable. It is not influenced by anything in this experiment, but may be changed to observe its effect on the dependent variable. It is possible to have more than one dependent variable in an experiment, but only one independent variable.
No, having one plant with light and another without light would not be considered a control experiment. A control experiment would involve having a third plant with no changes made to serve as a baseline for comparison.
Independent variables are factors in a study that are manipulated or controlled by the researcher in order to observe their effect on the dependent variable. They are variables that are believed to influence the outcome of an experiment or study.
The height of the ramp should be the only variable in Rebecca's experiment. All other factors should be kept constant to isolate the effect of ramp height on the speed of the marble.
Controlled
Independent variable. It is the variable that is deliberately manipulated or changed by the researcher in order to observe its effect on the dependent variable.
The independent variable is the only variable purposely changed during an experiment to test the hypothesis. It is manipulated by the researcher to observe the effects on the dependent variable.
Controlled Experiment :Pcontrolled experiment.
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
Fifteen turtles are fed iceberg lettuce and vitamins, while another fifteen turtles are fed only iceberg lettuce
A controlled experiment. In a controlled experiment, one variable (independent variable) is changed or manipulated while all other variables are kept constant to observe the effect on the dependent variable. This allows researchers to determine the specific impact of the variable being tested.

manipulated variable
A single-variable experiment, also known as a one-factor experiment, is one in which only one variable is manipulated at a time while keeping all other variables constant. This allows researchers to isolate the effects of that specific variable on the outcome of the experiment.
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.
