Experimental Design
I am going to conduct my experiment at my house. Also I will be only one conducting the experiment. I am going to have 2 trails to make a reliable conclusion. As I conduct my experiment I will be getting all of the data and with that data it will go right on to a spread sheet. I will put it on a spread sheet as I am measuring the bread rise.

 * You need 6-11 servings of grain a day it comes from bread, cereal, rice, or pasta. Bread is high in fiber.
 * We explain common words you may have heard, such as "sponge" and "rise," and cover the ingredients and equipment you'll need to get started. Scientific-sounding terms like "fermentation" and "proofing" can lead many to conclude that this is a subject best left to professionals.
 * There are more then 70 different kinds of bread. And they all start the same flour, sugar, yeast, and water. Four simple things that you can get.
