My son and I did a very similar experiment for his science fair project last year and he won "Best in Show" for K-2. We used chocolate chip cookie dough without the chips. We cooked them on a pan, on parchment on Reynolds Release and on Silpat. We measured cookie diameter, color and taste/texture. For all the bakers out there - this type if experiment can make the science fair a lot more fun (& tasty)!
