Swimming Upstream: Relating Trapped Energy in Organic Hydrogenations to Use of Reduced Hydrocarbons as Energy Sources
Shane E. Hendrickson, Wenatchee Valley College
An activity designed to inform the student of the potential and pitfalls of storing energy by the generation of reduced organic molecules, particularly as pertains to the generation of ethanol from molecules of a greater oxidation state and the ultimate fate of oxidized carbon when the energy potential is realized. As a part of a discussion of sustainability issues, the activity will be part of a discussion of global energy generation and use and couched in a form similar to the US energy flow trends.

The Sustainability Triangle: How Do We Apply Science to Decision Making?
Brian Naasz, Pacific Lutheran University
This writing assignment uses the "Sustainable Development Triangle" as a framework to critically evaluate an environmental issue of the student's choice. This learning activity provides an opportunity for an introductory chemistry student to use the sustainability's "Triple Bottom Line" as a tool to use material learned in the classroom to look at how environmental science helps inform economic and social/cultural factors in the development of sustainable solutions to our environmental challenges.
