Teaching Tips | Science | Pedagogy |
- Students should be familiar with photosynthesis and respiration prior to watching the video.
About the Science
- Discusses how human activities have increasingly affected the quantity of greenhouse gases in the atmosphere. Research scientists demonstrate and talk about their research, results and implications of increasing CO2 concentrations.
- Scientists debunk the myth that CO2 increase is positive for plants (a common argument being made when looking at photosynthesis - if plants need CO2 to live, an increase of CO2 is good for plants).
- The current CO2 level in the atmosphere is 394 ppm (March 2012)- the number in the video is out of date.
- Comments from expert scientist: The video is excellent scientifically in giving the message to the 5th and 6th graders that CO2 increase does not just warm the earth atmosphere, but it impacts the ecosystems such as the rain forests, and that the impacts lead to feed backs that can in turn enhance the CO2 budget of the atmosphere. It would be great to provide some messages regarding the long residence time of CO2 in the atmosphere.
About the Pedagogy
- A background essay, discussion questions, and a link to standards are provided.
- Main characters in video are two students (an Asian girl and a Caucasian boy) who discuss the greenhouse effect. Students will likely be able to relate to these characters.

Disciplinary Core Ideas: 9
MS-ESS2.D1:Weather and climate are influenced by interactions involving sunlight, the ocean, the atmosphere, ice, landforms, and living things. These interactions vary with latitude, altitude, and local and regional geography, all of which can affect oceanic and atmospheric flow patterns.
MS-ESS3.C1:Human activities have significantly altered the biosphere, sometimes damaging or destroying natural habitats and causing the extinction of other species. But changes to Earth’s environments can have different impacts (negative and positive) for different living things.
MS-ESS3.D1:Human activities, such as the release of greenhouse gases from burning fossil fuels, are major factors in the current rise in Earth’s mean surface temperature (global warming). Reducing the level of climate change and reducing human vulnerability to whatever climate changes do occur depend on the understanding of climate science, engineering capabilities, and other kinds of knowledge, such as understanding of human behavior and on applying that knowledge wisely in decisions and activities.
MS-LS1.C1:Plants, algae (including phytoplankton), and many microorganisms use the energy from light to make sugars (food) from carbon dioxide from the atmosphere and water through the process of photosynthesis, which also releases oxygen. These sugars can be used immediately or stored for growth or later use.
MS-LS2.C1:Ecosystems are dynamic in nature; their characteristics can vary over time. Disruptions to any physical or biological component of an ecosystem can lead to shifts in all its populations.
MS-LS2.C2:Biodiversity describes the variety of species found in Earth’s terrestrial and oceanic ecosystems. The completeness or integrity of an ecosystem’s biodiversity is often used as a measure of its health
MS-LS4.D1:Changes in biodiversity can influence humans’ resources, such as food, energy, and medicines, as well as ecosystem services that humans rely on—for example, water purification and recycling.
MS-PS3.D1:The chemical reaction by which plants produce complex food molecules (sugars) requires an energy input (i.e., from sunlight) to occur. In this reaction, carbon dioxide and water combine to form carbon-based organic molecules and release oxygen.
MS-PS3.D2:Cellular respiration in plants and animals involve chemical reactions with oxygen that release stored energy. In these processes, complex molecules containing carbon react with oxygen to produce carbon dioxide and other materials.

HS-ESS2.D1:The foundation for Earth’s global climate systems is the electromagnetic radiation from the sun, as well as its reflection, absorption, storage, and redistribution among the atmosphere, ocean, and land systems, and this energy’s re-radiation into space.
HS-ESS2.D3:Changes in the atmosphere due to human activity have increased carbon dioxide concentrations and thus affect climate.
HS-ESS2.E1:The many dynamic and delicate feedbacks between the biosphere and other Earth systems cause a continual co-evolution of Earth’s surface and the life that exists on it.
HS-ESS3.C1:The sustainability of human societies and the biodiversity that supports them requires responsible management of natural resources.
HS-LS1.C1:The process of photosynthesis converts light energy to stored chemical energy by converting carbon dioxide plus water into sugars plus released oxygen.
HS-LS1.C4:As a result of these chemical reactions, energy is transferred from one system of interacting molecules to another. Cellular respiration is a chemical process in which the bonds of food molecules and oxygen molecules are broken and new compounds are formed that can transport energy to muscles. Cellular respiration also releases the energy needed to maintain body temperature despite ongoing energy transfer to the surrounding environment.
HS-LS2.C2:Moreover, anthropogenic changes (induced by human activity) in the environment—including habitat destruction, pollution, introduction of invasive species, overexploitation, and climate change—can disrupt an ecosystem and threaten the survival of some species.
HS-LS4.D2:Biodiversity is increased by the formation of new species (speciation) and decreased by the loss of species (extinction).
HS-PS3.D2:The main way that solar energy is captured and stored on Earth is through the complex chemical process known as photosynthesis.
