How does the leavening agent affect the bread and how much it rises? Which leavening agent makes bread rise the most?

If we make 5 different breads, each with a different leavening agent, (yeast, baking soda, homemade sourdough, commercial sourdough, and sourdough made from dennis’ starter,) then the yeast will make the bread rise the most because it is the most commonly used leavening agent.

6. Observations​: After baking, measure the height of each loaf. Then taste each one and record your observations.

7.​ ​Analysis & Conclusion​: Explain your results. Your explanation should correctly use the following terms, and whether or not your hypothesis was proven or disproven: The results of this experiment did not support my hypothesis. The yeast bread did not rise the most. The breads that rose the most were the baking soda bread and the sourdough bread made from Dennis’ starter. ● ● ● ● ● ● ●
