Question

1. daniel wanted to test how the mass of a paper airplane affected the distance it would fly. paper clips were added before each test flight. as each paper clip was added, the plane was launched to determine how far it would fly

a. independent variable (iv):
b. dependent variable (dv):
c. control:
d. constants:

Explanation:

Part a: Independent Variable (IV)

The independent variable is what is changed or controlled in an experiment to test its effect on the dependent variable. In this experiment, the mass of the paper airplane is changed by adding paper clips, so the number of paper clips (or mass of the paper airplane) is the IV.

The dependent variable is what is being measured or observed, and it depends on the independent variable. Here, we are measuring how far the paper airplane flies, which depends on its mass (IV).

A control in an experiment is the group or condition that is used as a standard for comparison. In this case, the paper airplane without any paper clips (or the original paper airplane) would be the control to compare with the planes having paper clips added.

Answer:

The number of paper clips added (or the mass of the paper airplane)

Part b: Dependent Variable (DV)
