Teaching Tips

  • Consider using the Switch website to have students do a research project on the pros and cons of different types of energy sources. Then, as a class they can create an energy portfolio.
  • Note that this website will play multiple short videos. Instructor may want to review and choose videos of interest in the series.

About the Science

  • The video describes how efficiency reduces energy imports and helps stabilize prices. Issues around increasing the efficiency of power plants are discussed as well as the problems that accompany this process.
  • This video is a segment of a feature documentary entitled Switch. Dr. Scott Tinker, Director of the Bureau of Economic Geology and the State Geologist of Texas, narrates the video.
  • Switch is part of the Switch Energy Project, a multi-pronged effort designed to build a balanced national understanding of energy.

About the Pedagogy

  • Supporting educational resources are provided on the website.
  • Some economics vocabulary may need to be defined, e.g. “incentivize”, “supply side”.

Technical Details/Ease of Use

  • This video is also available on http://vimeo.com/channels/303773.
  • Clear, simple, slowly paced.
  • Links to other useful resources on different issues and topics are provided on the website.

Middle School

Disciplinary Core Ideas: 1

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.

Cross Cutting Concepts: 2

Energy and Matter

MS-C5.3:Energy may take different forms (e.g. energy in fields, thermal energy, energy of motion).

MS-C5.4:The transfer of energy can be tracked as energy flows through a designed or natural system.

High School

Disciplinary Core Ideas: 10

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.

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.A3:These relationships are better understood at the microscopic scale, at which all of the different manifestations of energy can be modeled as a combination of energy associated with the motion of particles and energy associated with the configuration (relative position of the particles). In some cases the relative position energy can be thought of as stored in fields (which mediate interactions between particles). This last concept includes radiation, a phenomenon in which energy stored in fields moves across space.

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-PS3.B4:The availability of energy limits what can occur in any system.

Cross Cutting Concepts: 2

Energy and Matter

HS-C5.2:Changes of energy and matter in a system can be described in terms of energy and matter flows into, out of, and within that system.

HS-C5.3:Energy cannot be created or destroyed—only moves between one place and another place, between objects and/or fields, or between systems.
