A student predicts that more sugar will dissolve in warm water than in cold water. she puts some water in a container, adds suga
r, and then stirs. the amount of undissolved sugar is then observed. when this student repeats the experiment to verify her prediction, the only thing that should change is the -
The water temperature is our dependent variable in this experiment, because we are seeing if it will dissolve more sugar when it is warm. In order to prevent experimental errors, all other factors must stay the same.
