Medical Sutures Experiment in St. Paul Central High School

Chemistry department undergraduate, Ming Yu, and Dr. Wissinger visited the classrooms of chemistry teachers Craig Karlen and Alka Goyal to introduce the topic of plastics and the environment through a medical sutures experiment.  Five classes of approximately 25 students performed the two day experiment learning about the relationship between size and composition to properties of polymers.  The experiment addresses Next Generation Science Standards that includes engineering requirements.
