How much yeast do i add?!
but i have a question.. how much yeast do i add to the bags?
should i add one whole packet of 1/4 cup active dry yeast.. or can i just add half the packet? also, do i need to proof the yeast?
this is the experiment:
One of my favorites was done by adding yeast to a plastic zip-lock bag with different amounts of sugar and water. You can use regular bread yeast found at the grocery store. Make one zip lock bag with just yeast and water, one with one teaspoon of sugar, one with 2 teaspons of sugar, and one with 4 teaspoons of sugar. The bags will swell up to different sizes. The purpose would be to see which bag of yeast, water, and sugar produces more gas thereby measuring the consumpton of the sugar by the yeast.
Answers: i got this from someone on yahoo answers..and if it was you..thanks! you really helped me out!..

I'm not exactly sure but in my brewing experience one packet of dry yeast is enough to brew 5 gallons of beer or wine so I don't think it would take much for just a zip lock bag. However yeast like any other organism needs more than just sugar and water to live, there are no nutrients for them to feed on, if you go to a home brew store you can pick up a bottle of yeast nutrient or some wine and mead recipes call for raisins as yeast food.
Unlike wine and beer yeasts, bread yeast is designed to produce the maximum amount of carbon dioxide. You can get away with splitting the packet among the three bags. Even a quarter-teaspoonful of yeast per bag will give you results. Just be sure to use exactly the same amount in each bag and to keep the bags at the same temperature. What your experiment is doing is the same thing as proofing the yeast. There is no need to do it beforehand.
