As butter cookies are the most common and plain cookies, i decided to use them as the test subject. I will use different cookie sheets: light/dark-colored, steel/aluminum. I wanted to find out how does the different types of cookie sheets affect the outcome of the cookies. I went to research and found out that the different types of cookie sheets do affect the outcome of the cookies. However, the amount of sugar, egg and flour also affect the cookie. That was when I was unsure about how to carry out my experiment. However, after much thought, I decided that the amount of sugar, flour and eggs in my cookie dough will not affect the difference in each batch of cookies. This is because the cookie dough used for the different trials are all the same. Since the amount of sugar, flour or eggs will not have any chemical reaction with the cookie sheet, the difference in the outcomes will still be the same.
