A group of students was asked to invest igate
how fast sugar dissolves in cold and in hot w ater .
6. If this is going to be a fair test, what variables
should they control?
a. Amount of water and sugar in each cup,
method of stirring, time when the solid is
added to water, how long each solution is
stirred.
