I love cookies! In fact, I just had two warm chocolate chip cookies for dessert tonight. I bet that you have a student or twenty that enjoys cookies too. TED-Ed has a fun lesson that you can use to teach some science concepts through cookies. In the TED-Ed lesson about the chemistry of cookies students learn why you shouldn’t eat raw dough, the temperature at which salmonella is killed, why cookies spread-out (or don’t spread if the dough is not correct), and what our noses tell us about cookies. The video from the lesson is embedded below.
