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.
Which of the following variables does Pedro need to control during his experiment?
A. Temperature only
B. Temperature and volume of water
C. Movement of air and evaporation rate
D. Movement of air only​
