Pedro is planning to model how changes in weather affect evaporation from lakes. For his second experiment, he wants to test how winds affect the evaporation rate. He places one beaker with 300 mL of water in an area away from any fans, and he places another beaker with 300 mL of water near a small fan.

What is the dependent variable in Pedro's experiment?

A. Volume of water

B. Evaporation rate

C. Temperature

D. Movement of air

Jace Ferguson · Answer 1

Since Pedro is to test the effect of the wind to the evaporation rate, the independent variable is the wind. The value that is to be affected by the wind is the evaporation rate. Hence, this is the independent variable. The answer to the question is therefore letter B.
