Part 3 did not contain that variable. The question wants you to say part 2 as that is the obvious answer, but it's a trick. Part 2 actually does contain that variable if you look hard enough.
But I didn't tell you that.
The part of the experiment that can be changed is called the independent variable. This variable is manipulated by the researcher to observe its effect on the dependent variable, which is the outcome being measured in the experiment.
An independent variable is a part of an experiment that can change. This is the variable that the scientist manipulates or controls in order to observe its effect on the dependent variable.
The part of the experiment that is changed and tested is called the independent variable. This variable is manipulated or controlled by the researcher to observe its effect on the dependent variable.
The part of an experiment that you intentionally vary or manipulate is called the independent variable. This variable is controlled by the experimenter to observe its effect on the dependent variable, which is the outcome or response being measured.
The researcher manipulates the independent variable in an experiment. This is the variable that is intentionally changed to observe its effect on the dependent variable.
The element of an experiment that doesn't contain the variable is called the "control"
The control does not contain a variable!:)
this group is called the control group. the one that changes is called the variable. as in, it can vary. :) hope this helps!

Yes, the part of the experiment that is changing is the variable, or the dependent variable. The independent variable, or the control, is the part that stays the same.
