A student conducts an experiment to determine how the temperature of water affects the time for sugar to dissolve. In each trial, the student uses a different amount of water and a different temperature of water.

Answer: The student changed more than one independent variable.

Explanation:

     What is the difference between dependent and independent variables?

           The independent variable is the variable you change. For example in this experiment, changing the temperature of the water.

           The dependent variable is the variable you don't change yourself, but changes based on the independent variable. In this experiment, it would be the time it takes for the sugar to dissolve.

     If we change two independent variables (in this student's experiment, the temperature and amount of water), then we cannot clearly see the answer to our question as we do not have the correct data.

     This is why you should only change one independent variable when conducting an experiment.
