It’s time to take a look at your life! As part of CHF's Thanks to Chemistry project, we present the three-part series The Stages of Life. These shows spotlight the common chemistry of childhood, adulthood, and old age. Today’s episode centers on children. First, Pennsylvania State University’s Koraly Pérez-Edgar talks about what happens in the brains of children. Then, Sruthi Pinnamaneni steps into the lab—the crayon lab where crayons are made—to find out why these sticks of color are such an important part of childhood.
