A student drops three blocks from the same height and measures the time it takes for the blocks to hit the ground. Each block has a different mass. What is the dependent variable in the experiment?

the volume of the blocks

the drop height

the mass of the blocks

the time for the blocks to hit the ground

The dependent variable in the experiment is time taken for the blocks to hit the ground.

Every experiment must have a dependent variable and an independent variable.

The experiment seeks to determine the effect of changes in the independent variable on the dependent variable. Hence, the independent variable is changed and the effect of this change on the dependent variable is monitored throughout the experiment.

In this case, the independent variable is the mass of the blocks while the dependent variable is the time taken the block to hit the ground.
