In a controlled experiment, the number of independent variables that can be worked with at a time depends on the specific experiment and research question being investigated. However, it is generally recommended to focus on one independent variable at a time in order to isolate its effects and analyze the results more accurately.
To determine the number of independent variables in a controlled experiment, you can refer to the experimental design. Look for the factors that are intentionally manipulated or changed by the researchers. These are the independent variables.
If you have access to a video or other documentation of the experiment, you can observe how many independent variables were changed during the experiment. This can give you a clue about the number of independent variables that can be worked with at a time. In this specific case, if you noticed that only one independent variable was changed in the video, then the answer would be 1.
