Here's how to classify each factor:

• Independent Variable: This is the variable that is intentionally changed or manipulated by the experimenter. In this experiment, the student is testing "different room temperatures," so room temperature is the independent variable.
• Dependent Variable: This is the variable that is measured or observed in response to changes in the independent variable. The experiment records "how long it takes for the balloon to fall," so the time taken for the balloon to fall is the dependent variable.
• Control Variable: These are factors that are kept constant throughout the experiment to ensure that only the independent variable is affecting the dependent variable. To make sure the experiment is fair, factors like the size of the balloon, the material of the jumper, or the type of wall should be kept the same.

Here is the completed classification for the visible factors:

Factor	Independent	Dependent	Control
The time taken for the balloon to fall		✅
The size of the balloon			✅
