Ben makes five paper helicopters with different wing lengths. He drops
them the same way from a height of two meters for five trials each. He
records the amount of time it takes for each helicopter to fall to the
ground. What is the independent variable?
Dropping the same way
Wing Length
Amount of time it takes the helicopter to hit the floor
Dropping from the same height

In this experiment, Ben is using on purpose paper helicopters with different wing lengths. This shows this factor is the one Ben is changing or controlling to find out if the wing length affects the time the paper helicopter flies before falling and in experiments the factor controlled is known as the independent variable. Because this factor is not manipulated by other factors but by the researcher and this affects other variables. For example, it is expected the wing length affects the flying time. According to this, the correct answer is B.

The correct answer is B. Wing Length

The following information should be considered:

In the given experiment, since Ben is using on-purpose paper helicopters having different wing lengths.
This represent this factor is the one Ben is changing or controlling to find out in the case when the wing length impact the time the paper helicopter flies prior falling and in experiments the factor controlled is known as the independent variable.
