8. Curriculum Overview Lesson Title Lesson Description Lesson 1: Introduction to Bioenergy Gives background and purpose of CenUSA Bioenergy project; gives brief overview of bioenergy, renewable vs. non-renewable energy. Lesson 2: Carbon Cycle Explains the carbon cycle and potential impacts it could have on the environment if disrupted. Lesson 3: Photosynthesis Defines role of plants in carbon cycle; detailed discussion of light-dependent and light-independent reactions; lab activities investigate chlorophyll and transpiration. Lesson 4: Nitrogen Cycle Discusses natural and anthropogenic nitrogen movement through soil, water, and air; lab activity has students analyze variables associated with erosion associated with nitrate leaching. Lesson 5: Fermentation Outlines the steps involved in fermentation and how biological enzymes are used to convert sugars into ethanol; lab activity will have students compare fermentation outputs of different feedstocks.

9. Curriculum Overview Lesson Title Lesson Description Lesson 6: Corn to Ethanol Appraises the use of corn for ethanol production and its impact on the environment, industry, and land use; lab activity has students complete the initial steps of the wet milling process by extracting starch. Lesson 7: Soybeans to Biodiesel Examines the impacts on the environment and industry due to soy production for food and biofuels; lab activity introduces transesterification as a biodiesel production method. Lesson 8: Biomass and Biochar Reviews biomass in the context of fuel usage, contrasts biomass and fossil fuels, introduces biochar and potential uses; lab activity results in creation of mini-pyrolyzer and biochar production. Lesson 9: Second Generation Biofuels Introduces the concept of second-generation biofuels made from cellulose; lab activity has students compare and contrast different cellulosic feedstock and their sugar output by performing hydrolysis. Lesson 10: Perennial Grass Development Describes the process of feedstock development through breeding and selection; lab activity has small groups of students complete a plant breeding simulation.

10. Curriculum Overview Lesson Title Lesson Description Lesson 11: Countries Using Bioenergy Presents a picture of bioenergy usage around the world, potential for future usage, as well as pros and cons of worldwide adoption of bioenergy; lab activity has students create bioenergy action plans for international countries. Lesson 12: Economics of Bioenergy Outlines potential economic impacts of bioenergy on numerous stakeholders, including food and industry; lab activity is a role-playing activity that simulates a congressional hearing about the future of biofuels in the United States. Lesson 13: Environmental Impact of Bioenergy Examines potential environmental impacts, both positive and negative, as a result of increased bioenergy usage; lab activity has students make decisions as farmers that have short-term and long-term economic and environmental impacts. Lesson 14: Careers in Bioenergy Concludes the curriculum by illustrating the diverse nature of potential careers in bioenergy; lab activity has students explore different careers by assuming the identity of a bioenergy professional.
