Identify the independent variable, dependent variable, and constant in the following problem: If you plant hydrangeas in your garden, will the flowers be pink or blue?

The independent variable is the one you change, and the dependent variable is the one that changes because the independent changed (i think). The constant variable is the thing you can't change so the experiment is fair.

Independant: whatever causes the flowers to change color

Dependent: the flowers change color

Constant: same soil type, same conditions, etc.
