Question

Pedro is planning to model how changes in weather affect evaporation fromlakes. For his second experiment, he wants to test how winds affect theevaporation rate. He places one beaker with 300 mL of water in an area awayfrom any fans, and he places another beaker with 300 mL of water near asmall fan.What is the independent variable in Pedro's experiment?
