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?
size of the box

temperature of the box

timing of the cricket’s chirps

volume of the cricket’s chirps

Answer 1

Answer: timing of the cricket's chirps.

Explanation:

In an experimental setup, an independent variable is the variable which can be changed or manipulated in an experiment, the affect of which can be observed on the dependent variable.

Dependent variable is the variable the changes in which are the outcomes of the experiment.

According to the given situation, timing of the cricket's chirps is the example of dependent variable which changes due to the affect of temperature.

Answer 2

It should be the volume of the cricket's chirps. Dependent variable is what you will measure in an experiment.
