Which of the following was the dependent variable in this investigation?

Rationale

The flight distance was the dependent variable in this investigation.

In scientific experiments, the dependent variable is the outcome that is measured in response to changes in the independent variable. In this case, the flight distance is what was observed and measured to determine the effects of any manipulations made during the investigation.

A (The wingspan) YOUR ANSWER

The wingspan refers to the distance from one wingtip to the other when the wings are fully extended. While it may influence flight performance, it is not the variable being measured as a response in this experiment. Instead, it is likely an independent variable that could affect the dependent variable (flight distance).

B (The flight distance) CORRECT

The flight distance is the correct answer as it is the variable that was measured to assess the outcome of the investigation. By observing how far the object flew, researchers can draw conclusions about the effects of any experimental conditions applied during the study.

C (The stopwatch) YOUR ANSWER

A stopwatch is a tool used to measure time, which could be relevant in timing the flight but does not constitute a variable that is measured for outcomes. It serves a functional role in the experiment but does not directly relate to the dependent variable.

D (The tape measure) YOUR ANSWER

The tape measure is a measurement tool used to quantify distance. Although it is used to determine the flight distance, it is not a variable itself but rather an instrument employed in the process of measuring the dependent variable.

Conclusion

In this investigation, the dependent variable was the flight distance, which was measured to evaluate the effects of any changes made during the experiment. The wingspan, stopwatch, and tape measure serve different roles within the investigation and do not represent the outcome being assessed. Understanding the distinction between dependent and independent variables is crucial for analyzing experimental results effectively.
