Teaching Tips

  • Additional biofuel high school experiments are located at Great Lakes Bioenergy Research Center http://www.glbrc.org/education/educationalmaterials
  • Educators may consider discussing the local availability of biofuels and how they could be transported to other regions, once developed into a transportation fuel, just like petroleum oil.

About the Science

  • The video describes use of sugar in Brazil for bio fuel. It describes why this process has challenges (use of a food crop, water and fertilizers, scale-up, and technical limitations to converting cellulose from plant to biofuel). It suggests that we should expand beyond non-food crops.
  • Comments from expert scientist: This activity consists of a series of interviews of different high profile people from prestigious organizations within the biofuels research and broader fuels communities. This resource should be used to discuss the potential role of biofuels in the future energy portfolio. This resource assumes some familiarity with the current use of corn ethanol and biofuels research beyond corn ethanol. It is important to frame these resources before sending students diving into them.

About the Pedagogy

  • Lesson plans are not currently available but projected to be in late 2013.

Technical Details/Ease of Use

  • No transcript or closed captioning available.

Middle School

Disciplinary Core Ideas: 3

MS-PS1.B3:Some chemical reactions release energy, others store energy.

MS-PS3.B2:The amount of energy transfer needed to change the temperature of a matter sample by a given amount depends on the nature of the matter, the size of the sample, and the environment.

MS-ESS3.A1:Humans depend on Earth’s land, ocean, atmosphere, and biosphere for many different resources. Minerals, fresh water, and biosphere resources are limited, and many are not renewable or replaceable over human lifetimes. These resources are distributed unevenly around the planet as a result of past geologic processes.

High School

Disciplinary Core Ideas: 8

HS-PS3.A1:Energy is a quantitative property of a system that depends on the motion and interactions of matter and radiation within that system. That there is a single quantity called energy is due to the fact that a system’s total energy is conserved, even as, within the system, energy is continually transferred from one object to another and between its various possible forms.

HS-PS3.A2:At the macroscopic scale, energy manifests itself in multiple ways, such as in motion, sound, light, and thermal energy.

HS-PS3.B1:Conservation of energy means that the total change of energy in any system is always equal to the total energy transferred into or out of the system.

HS-PS3.B2:Energy cannot be created or destroyed, but it can be transported from one place to another and transferred between systems

HS-ESS3.A1:Resource availability has guided the development of human society.

HS-ESS3.A2:All forms of energy production and other resource extraction have associated economic, social, environmental, and geopolitical costs and risks as well as benefits. New technologies and social regulations can change the balance of these factors.

HS-ETS1.A2:Humanity faces major global challenges today, such as the need for supplies of clean water and food or for energy sources that minimize pollution, which can be addressed through engineering. These global challenges also may have manifestations in local communities

HS-ETS1.B1:When evaluating solutions, it is important to take into account a range of constraints, including cost, safety, reliability, and aesthetics, and to consider social, cultural, and environmental impacts.
