WebThe Life Cycle of Plastics. Students complete the physical journey of ocean plastics by studying microplastics. They imagine the so-called Great Pacific Garbage Patch, and then read an article to address evolving understandings. Students form a polymer chain to simulate the process of photodegradation. A polymer is a substance or material consisting of very large molecules called macromolecules, composed of many repeating subunits. Due to their broad spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fun…
