- Educator could divide class into gas teams to explore each one of these scenarios, then report back to the rest of the class.
- Combine interactive with other resources on the site to support a deeper understanding of the content.
About the Science
- A simple informational interactive that describes the important properties and characteristics of carbon dioxide, oxygen, and ozone.
- Gives a cursory explanation of the greenhouse effect and elements of the carbon cycle.
- NOTE: The stated present level of CO2 is incorrect. For the current CO2 level see: http://www.esrl.noaa.gov/gmd/ccgg/trends/
- Comments from expert scientist: There is only little science in this presentation, which is probably appropriate for a broad audience. The comparison with Mars and Venus is good because it suggests that we understand quite well that CO2 is an important factor in setting the temperature. What's more, that suggestion reflects the truth. The last two illustrations ("where does O2 come from" and the "elixir of life") under "oxygen" are excellent.

Disciplinary Core Ideas: 4
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.
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-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.
Cross Cutting Concepts: 3
MS-C5.1:Matter is conserved because atoms are conserved in physical and chemical processes.
MS-C5.4:The transfer of energy can be tracked as energy flows through a designed or natural system.
MS-C2.2:Cause and effect relationships may be used to predict phenomena in natural or designed systems.
Disciplinary Core Ideas: 5
HS-ESS2.D2:Gradual atmospheric changes were due to plants and other organisms that captured carbon dioxide and released oxygen.
HS-ESS2.D3:Changes in the atmosphere due to human activity have increased carbon dioxide concentrations and thus affect climate.
HS-ESS2.D4:Current models predict that, although future regional climate changes will be complex and varied, average global temperatures will continue to rise. The outcomes predicted by global climate models strongly depend on the amounts of human-generated greenhouse gases added to the atmosphere each year and by the ways in which these gases are absorbed by the ocean and biosphere.
HS-LS2.B3:Photosynthesis and cellular respiration are important components of the carbon cycle, in which carbon is exchanged among the biosphere, atmosphere, oceans, and geosphere through chemical, physical, geological, and biological processes.
HS-PS3.D2:The main way that solar energy is captured and stored on Earth is through the complex chemical process known as photosynthesis.
Cross Cutting Concepts: 7
HS-C2.1:Empirical evidence is required to differentiate between cause and correlation and make claims about specific causes and effects.
HS-C2.2:Cause and effect relationships can be suggested and predicted for complex natural and human designed systems by examining what is known about smaller scale mechanisms within the system.
HS-C2.4:Changes in systems may have various causes that may not have equal effects.
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.
HS-C5.4: Energy drives the cycling of matter within and between systems.
