Okay, there are a lot of different types of yeasts. The stuff you get at the grocery store is bread yeast. There are other kinds of yeast used to make beer, wine, or even hard liquor. You can get these at any brewing supply store. (Most of them do mail-order, so if there isn't anything locally, you can just Google brewing supply.)
You'll need to talk to your teacher about the details of the project: you can do a simple one with bread yeast and molasses. Make solutions of water and molasses: one with 5 grams of molasses, one with 10 grams, and one with 15 grams. Put the mixtures in bottles (20 oz. soda bottles will work). Add the same amount of yeast to each one, then cover the neck of each bottle with a balloon. Let the bottles sit in a warm place, and see which balloon is biggest. Yeast eats sugar and produces alcohol and carbon dioxide. The more sugar the yeast has, the more CO2 it will produce. The only place it has to go is up into the balloon.
Again, work with your teacher to iron out the details.
Hope this helps.
