Teaching Tips | Science | Pedagogy |
- Educators will want to tie this video into a discussion about the changing mix of energy sources in the US.
About the Science
- Video characterizes hydrogen as an energy source, but it can also be described as an energy store/carrier.
- Good explanation of how electricity is produced by using different methods and fuel sources.
- Comments from expert scientist: A good overview with strong visuals. Corrections: 1) Hydrogen is not an energy source. It is an energy currency. 2) Better to use the term wind turbines not wind-mills. 3) Pictures of solar thermal were shown while discussing PV. 4) Mention is made of bird kills by windmills. Should also mention that house cats etc kill many more birds. would be nice to mention linkage between pop growth and energy demand.
About the Pedagogy
- Background essay and discussion questions are available on the webpage.
- This is mostly a "just the facts" kind of presentation, with few opportunities for substantive inquiry or discussion. The provided questions assess only comprehension of the video content.

Disciplinary Core Ideas: 2
MS-PS1.B3:Some chemical reactions release energy, others store energy.
MS-PS3.A4:The term “heat” as used in everyday language refers both to thermal energy (the motion of atoms or molecules within a substance) and the transfer of that thermal energy from one object to another. In science, heat is used only for this second meaning; it refers to the energy transferred due to the temperature difference between two objects.
Disciplinary Core Ideas: 7
HS-PS3.A2:At the macroscopic scale, energy manifests itself in multiple ways, such as in motion, sound, light, and thermal energy.
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.D1:Although energy cannot be destroyed, it can be converted to less useful forms—for example, to thermal energy in the surrounding environment.
HS-PS3.D3:Solar cells are human-made devices that likewise capture the sun’s energy and produce electrical energy.
HS-PS4.B1:Electromagnetic radiation (e.g., radio, microwaves, light) can be modeled as a wave of changing electric and magnetic fields or as particles called photons. The wave model is useful for explaining many features of electromagnetic radiation, and the particle model explains other features.
HS-PS4.B3:Photoelectric materials emit electrons when they absorb light of a high-enough frequency
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.
Cross Cutting Concepts: 3
HS-C5.1:The total amount of energy and matter in closed systems is conserved.
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.
