Question

A student did an investigation to determine the effect the amount of air would have on plant growth. She planted identical

plants in 4 separate closed containers with different volumes of air. She measured the height of the plants after they had
grown for 3 weeks.
What is the dependent (responding) variable in her investigation?

Answer 1

Step-by-step explanation:

The responding variable always is measured against the variable that you have control over.

In this case, you have control over the volume of air.

The responding variable is the amount the plant has grown. This would be a good long term experiment to try for a science fair or just because you might be interested. It's a good simple idea.
