      Yeast is a tiny living organism! When you make bread you add flour (which the yeast uses as food) and warm water. The warm water makes the bread just the right temperature for yeast to grow. As the yeast grows it eats sugars found in the flour and releases carbon dioxide (a gas) as it does this. The carbon dioxide bubbles are what makes the bread rise!
