Life Cycle Assessment of Biofuels 101

Type of Resource



In this activity, students conduct a life cycle assessment of energy used and produced in ethanol production, and a life cycle assessment of carbon dioxide used and produced in ethanol production.

Performance Expectations

HS-ESS3-4   Evaluate or refine a technological solution that reduces impacts of human activities on natural systems.

MS-LS2-3   Develop a model to describe the cycling of matter and flow of energy among living and nonliving parts of an ecosystem.

HS-ETS1-1   Analyze a major global challenge to specify qualitative and quantitative criteria and constraints for solutions that account for societal needs and wants.

MS-ETS1-1   Define the criteria and constraints of a design problem with sufficient precision to ensure a successful solution, taking into account relevant scientific principles and potential impacts on people and the natural environment that may limit possible solutions

MS-ESS3-4   Construct an argument supported by evidence for how increases in human population and per-capita consumption of natural resources impact Earth's systems.
