Transcript of Kelvin Daci's bread experiment

Kelvin Daci's bread experiment
hypothesis
I hypothesize that the baking powder will work as a substitute for the yeast because the sodium bicarbonate when added with water will create carbon dioxide
process
Three types of bread will baked at four hundred degrees Fahrenheit for thirty minutes.
All three pieces will include the same ingredients in the same amounts with the exception of the baking powder.
Two pieces of bread will be made one using a third of the amount of baking powder and one using three times the amount of baking powder
Conclusion
Purpose of experiment
The purpose of this experiment is to test if baking powder witch contains sodium bicarbonate can substitute yeast when baking bread
Yeast makes bread rise because like all living organisms it releases carbon dioxide among other gasses when it dies. when the carbon heats up it expands making the bread expand with it.
Ingredients
1 cup of flour
1/2 teaspoon of salt
1/4 cup of water
1/2 teaspoon of vegetable oil
3/4 teaspoon of baking powder(one piece of bread will be made using 1/3 teaspoon of baking powder and one with 2 1/4 teaspoons of baking powder)
How does yeast make bread rise?
Results
After baking the bread it did expand much like it would have if yeast had been used. Also the bread using three time the amount of baking powder did expand more than the bread with the normal amount of baking powder.
original amount
