Question

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?

Answer 1

Answer:

Dependent variable: Blue or pink color of flowers.

Independent variable: The treatment given to hydrangea plants to change color.

Constant variables: The composition of the soil where hydrangeas are planted, and the atmospheric condition.

Explanation:

The independent variable is the variable that changes or is controlled for the study of its effects on the dependent variable, in this case, the independent variable is the treatment that hydrangea plants do to change color. The dependent variable is the variable that is measured, in this case, it will be the type of color, either blue or pink of the flowers. A constant variable is one that cannot be changed, in this case they would be the composition of the soil where hydrangeas are planted, and the atmospheric condition.

Answer 2

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.
