Scientific Knowledge:
From previous experiences with baking cookies we are aware that if you accidentally use baking powder instead of soda, the cookies will increase in thickness and will result in a sponge-like texture.
Baking soda and baking powder are similar, but have different reactions to the ingredients in baking cookies. Baking soda is also known as sodium bicarbonate, and once it meets heat, carbon dioxide is formed. The carbon dioxide is what gives rise to cookies and other baked goods. Baking powder, on the other hand, is a mixture of baking soda, powdered acid, and cornstarch (Baking 101: The Difference …show more content…

We concluded that only one trial is not sufficient enough to provide an accurate claim. It is not accurate because no measurement is precise so Byars’ cookie compared to ours will be different. By conducting more than one trial we would have many of the same cookies to compare their general features to Byars’ cookie. It would be easier to tell if in fact Byars did substitute baking powder for baking soda or if he did not.
Errors that could not be eliminated includes the fact that measurements are not precise,and the varying temperatures of the oven used. Because measurements are not precise, it is very unlikely that two cookies will be exactly the same, making it harder to reach an accurate claim. During the experiment we discovered that the oven had been set to a lower temperature than the 375° F specified in the procedures. This caused cookies to become undercooked without realizing is as to the fact we were following the procedure of leaving the cookie in only for nine to eleven minutes.
