Workshop Leaders: Professors Jane Wissinger and Michael Wentzel
Jane Wissinger presented to a full house of members of the American Association of University Women (AAUW). What a dynamic and engaged organization!
Cassandra Knutson (White Bear Lake HS), Cassie Javner (Shakopee HS) and Jane Wissinger hosted 20 high school teachers from across MN to learn about green & sustainable chemistry curriculum. Time was spent in lab performing experiments to gain hand-on experience with labs they might implement for their own programs.

Professor Jane Wissinger along with high school teachers, Cassie Knutson and Cassie Javner hosted a workshop for chemistry high school teachers with the goal of training high school chemistry teachers to bring Green & Sustainable Chemistry into their classrooms. Twenty teachers from across the state of Minnesota participated in the workshop June 20-22, 2017 in the Department of Chemistry.
Participants received instruction on the principles of green chemistry, industrial applications, and potential impacts to human health and the environment. Shared lesson plans illustrated how green and sustainable practices apply to secondary chemistry classrooms with education standards in mind. A wealth of resources were provided to aid the teachers in their implementation plans.
The teachers gained hands-on experience with ten different high school friendly experiments. These experiments modeled safer, cost-effective labs that minimized waste and are readt drop-in replacements for traditional more hazardous secondary chemistry labs that have been performed for decades. Topics such as bioplastics, polymeric medical sutures, and use of biomimicry were explored, demonstrating relevance to societal needs.
Professor Marc Hillmyer gave a key note address entititled: "Plants to Polymers: Why not?" as an introduction to CSP experiments performed. Also, a panel discussion was held with guests Emma Corcoran (White Bear Lake High School student and future U of MN student), Al Innes (MPCA), Pat Riley (Northfield High School teacher) and Tim Kapsner (Aveda) to allow dialog of "what impact teaching green chemistry" can have in the classroom.
This free workshop was funded by the Center for Sustainable Polymers (CSP), the Minnesota Corn Growers Association, and University’s Materials Research Science & Engineering Center (MRSEC) Research Experiences for Teachers (RET) program. Wissinger is a CSP investigator and is a leading expert in green chemistry. Her co-instructors were Cassandra Knutson from White Bear Lake High School, and Cassidy Javner from Shakopee High School. CSP summer undergraduate researcher, Abby Hilker, also helped with preparations and activities during the workshop.
Avalon School students tensile testing their bioplastic polymers with Nina Meltzer
Nina Meltzer shared the Center for Sustainable Polymer bioplastics experiment with 43 students at Avalon Charter School in St. Paul on April 12th. Students prepared a range of plant based bioplastics on the first day and performed tensile testing on the second day.
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.

CSP researchers Debbie Schneiderman and Lindsay Davis (Summer student) lead 25 high school girls in exploring the properties of absorbable and nonabsorbable medical sutures. These students were participating in the CSE's Exploring Careers in Engineering and the Physical Sciences program (ECEPS). The experiment has three modules: 1) students compare the threads or "sutures" that can be drawn from different molecular weights of polycaprolactone; 2) students test the tensile strength of different purchased medical sutures that are absorbable and non-absorbable; and 3) students observe their rate of degradation. Topics of discussion included the importance of developing new plastics that will degrade in the environment.
