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?

The independent variable in Pedro's experiment is the winds ( its presence and absence)

Step-by-step explanation:

The independent variable is the variable whose values do not depend on the values of another variable. It is also known as the input variable.

In the case study, the independent variable in Pedro's experiment is the winds ( its presence and absence)

no, because the sides are not congruent
