Thanks so much! This is helping me so much! Now I understand what he means by telling him what is happening chemically, but where does he want me to include that information?
I also agree with your suggestion of the different amounts of time each dough has sat in the refrigerator. I will use that, thanks!
Would 20 taste-testers be okay? 10 people that are in the same age group as me, and 10 that are adults? I'm not sure about the volunteers, and how many I need. Also, would I have to give them the cookies to taste at the same time, same place, etc.? Or it doesn't matter?
Lastly, like I said, my material and procedure list is due Friday. When I am listing the materials, do I say, "Ingredients to your favorite cookie recipe." Or do I actually list the recipe I'm using, along with the specific ingredients? Basically, do I make a general list, or a list specifically related to my experiment?
Thanks so much to everyone that is helping, I couldn't have been more understanding of the project than I am now without your help.
