Madeline Cooke squats in the dirt and leans over the stacked, wooden two-by-fours supporting a raised garden. Scissors at the ready, she trims away weeds and checks the health of rows of red-stemmed succulents. Although many might consider this jade-like plant — called purslane — a weed, it’s actually edible, often found in Asian soups, salads, and stews. And it’s packed with antioxidants.
Cooke, a UNC-Chapel Hill senior majoring in chemistry, spent six months last year helping organic chemistry professor Nita Eskew tend to these weedy plants so she could use them in her “Chemistry of Purslane” class. A Course-Based Undergraduate Research Experience (CURE), the class provides many students with their first active research experience.
“Some students don’t have the opportunity to do undergraduate research while they’re here, so this gives them the experience while also getting course credit,” Eskew explains. “I also wanted to get some type of chemistry research going in an undergrad lab course so students would have some purpose in their experiment other than making crystals and throwing them in the waste jar and walking out.”
Organic chemistry can be a little obscure, admits Eskew, so a course that highlights real-world applications draws more student attention. “It’s helpful to have something more concrete you can put your hands on,” says Eskew, adding that the class had so many applicants she couldn’t accept them all.
