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. What is wrong with this experimental design? The student did not change enough independent variables. The student changed more than one independent variable. The student does not have a dependent variable. The student needs to perform more trials.

According to the question, the student set out to study the influence of temperature of water on the time for sugar to dissolve but a different amount of water and a different temperature of water was used in each trial. This experiment is wrong because the student changed more than one independent variable.

The aim of the student in the experiment was to determine the influence of temperature of water on the time for sugar to dissolve.

This experiment should have one independent variable (temperature) and one dependent variable (time for sugar to dissolve).

However, the student also changed the amount of water used at each trial meaning that another independent variable has been introduced. This makes it difficult for us to arrive at reliable conclusions from the experiment.

The amount of water ought to have been held constant throughout the experiment.
