Chemistry of Cookies

You stick cookie dough into an oven and, magically, you get a plate of warm, gooey cookies. Except it’s not magic; it’s science. Stephanie Warren explains via basic chemistry principles how the dough spreads out, at what temperature we can kill salmonella, and why that intoxicating smell wafting from your oven indicates that the cookies are ready for eating. This is a TED-Ed Original lesson complete with Think questions, a Dig Deeper section of additional resources, and a Discuss section with guided discussion questions. Find hundreds of searchable Video Lessons at TED-Ed: Lessons Worth Sharing!
