Question

A student does an experiment for a science fair to study whether temperature affects the timing of a cricket’s chirps. The student keeps a cricket in an enclosed box that is heated to different temperatures each day for twelve days. The student records the cricket’s chirps by using a sound-activated microphone so the timing of the chirps can be measured. Which is the dependent variable in this experiment?

A. size of the box
B. temperature of the box
C. timing of the cricket’s chirps
D. volume of the cricket’s chirps

Answer 1

The dependent variable in the experiment is the timing of a cricket's chirps. Thus, the answer is letter C. This variable is dependent on the temperature of the box in which the cricket was placed. The students want to know the relationship between this two variables.
