Yeast is a very important group of fungi. The common yeast used in baking bread grows very fast. The basic idea in this lab is that the yeast will use an energy source and in doing so, will produce carbon dioxide gas. You’ll measure the amount of carbon dioxide (CO2) released during the growth of yeast. The growth of the yeast stops when the energy source has been used up by the yeast and CO2 production slows down or stops.
What is the variable ^^ ??
and according to this information what do you hypothesize the outcome of this experiment will be?

Well, the variable is the thing that you change during the experiments. So, are you using different sugars or different amounts of sugars and measuring the amount of CO2 produced? Then the independent variable is the sugar or the amount of the sugar and the dependent variable is the amount of CO2 produced.
Since you don't tell me what you are changing in the experiment, I can't offer a good hypothesis as to what will happen. You should be able to think about that, though. Will you get more CO2, or.....
