Question

the passage below describes an experiment. as susan played with a rubber band, she noticed that it seemed to stretch better after she had been holding it for a while. susan reasoned that materials like rubber must stretch better when they are warmed up. to test her idea, susan first gathered eight rubber bands. she put two rubber bands in the freezer, two in the fridge, two out at room temperature, and two out in the hot sun. fifteen minutes later, she gathered the rubber bands and measured how far each one could stretch. identify the independent and dependent variable in this experiment. the temperature of the rubber band the length the rubber band stretched independent variable dependent variable

Explanation:

Step1: Define independent variable

The independent variable is what is changed in an experiment. Here, Susan changes the temperature of the rubber - bands by putting them in different places (freezer, fridge, room temperature, hot sun).

Step2: Define dependent variable

The dependent variable is what is measured as a result of the change in the independent variable. Susan measures how far each rubber - band can stretch.

Answer:

Independent variable: the temperature of the rubber band
Dependent variable: the length the rubber band stretched
