J.J. Thompson proved the electron's existence through the cathode ray experiment.
The scientific term that could describe the group of prisoners who changed their diet in Goldberger's experiment is the "experimental group." This group would be compared to a control group to determine the effects of the changed diet.

Experimented is a past tense verb, not an adjective. The adjective would be experimental.
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.
the three kinds of variables are independent,dependent and controlled

There are three kinds of variables in an experiment. The independent variable is what you change in the experiment. It is important that you have only one independent variable in your experiment. You would not be able to draw reliable conclusions from the experiment if you altered more than one experimental condition. The dependent variable is what you measure in the experiment. Unlike the independent variable, an experiment can have more than one dependent variable because variations in the independent variable can have many different effects. For example, you might measure length of leaves and weight of roots to assess the growth of radish plants. Dependent variables can include amounts as well as amount data. Such data cannot be measured but is still useful when you describe and compare it.
If you wish to write an essay about a science experiment, you should describe the purpose of the experiment, and the way in which the experiment was performed, and the results of the experiment, and the conclusions that are drawn from those results. If you want to be fancy, you might also describe what further experiments may be needed to continue to explore the subject of the first experiment.
