Setup the Experiment

Students should work in groups of 2-4 to set up yeast cultures consisting of 50 mL of room temperature water and one packet of rapid rising yeast. Two teaspoons of sugar should be added to one culture only (the other culture is left alone as a control). Separate spoons or stirrers should be used to stir each mixture.

Within a few minutes, bubbles will begin to appear near the surface of the mixture with sugar.
