Integrating sustainability across and within the science curriculum of Gustavus Adolphus College * Chuck Niederriter, Amanda Hochstatter, Hasanga Samaraweera, Amy Audette, Kevin Clark Summer 2011 Meeting of the AAPT Omaha, NE * NSF DUE #

Goals: To Increase Interest in Science and Science-related Careers. Because energy usage, global warming, and energy conservation are currently topics of high interest for young people, course work in sustainability will draw more students into science. To Enhance Quantitative Literacy. The nature of sustainability is such that students are required to develop good quantitative skills in order to go beyond a conceptual level of understanding. To Increase Thermodynamic Literacy. Due to its abstract nature, thermodynamics is a difficult subject for science students and even more difficult for non-science students. However, the understanding of the basics of thermodynamics is important for responsible decision-making in a modern, energy-driven world. So, we believe that it is essential to ensure that the next generation of decision makers have a high level of thermodynamic literacy. To Improve Sustainability Literacy. A great deal of the science behind conservation, energy production, and energy management is new and evolving, which will challenge students, but can also create an exciting learning environment. To Emphasize the Interdisciplinary Nature of Science. Work in sustainability, as well as many other areas in science, is inherently interdisciplinary. It is important that students are aware of this so they can begin to see the connections between the scientific disciplines.

Overview of Project Develop labs and classroom materials that take advantage of student interest in energy and the environment to increase interest in science lead to an increase in quantitive literacy lead to an increase in thermodynamics and energy literacy help students see the interconnection between classes and the interdisciplinary nature of science
