Question

Does the size of the parachute affect its flight?

Answer 1

Independent Variable: flight
Dependent Variable: size of parachutes
Controlled Variables: precipitation, wind speed, person using parachute (weight), and the shape of the parachute.

The question is slightly broad; it does not specify whether the experiment focuses on the quality of the flight (stability in the air), speed of descent, or the distance it can travel. However, this is what I have come up with.
