The factors in an experiment that can be changed are: variables.

Here’s why:

1.Variables are the factors or conditions in an experiment that can be manipulated or controlled. There are usually three types of variables:

2.Independent variable: The factor that is deliberately changed or manipulated by the experimenter to observe its effect.

3.Dependent variable: The factor that is measured or observed in response to changes in the independent variable.

4.Controlled variables (or constants): The factors that are kept the same throughout the experiment to ensure a fair test.
