A micro-lecture that describes the vibrational modes of polyatomic molecules, how these modes determine whether the molecules are IR inactive or IR active and explains why most IR active polyatomic gas molecules are greenhouse gases.
A reading that discusses how chemical bonds in molecules respond to incident IR light and absorb IR energy during certain modes of vibration. The reading includes discussions on the vibrational modes of water vapor and carbon dioxide (CO2) molecules and explains why these gases act as greenhouse gases.
A classroom/laboratory activity that shows how to measure the rate of photosynthesis and its changes under different conditions including high concentrations of carbon dioxide, a potential contributor to climate change.
A reading that introduces hydrocarbons, fossil fuels, and the products of combustion of different hydrocarbons such as carbon dioxide- a greenhouse gas.
A reading that explains Earth’s equable climate in the past using the theories, Hadley Cells, Convective Cloud Feedback, Polar Stratospheric Clouds, and Tropical Cyclones.
A set of hands-on laboratory activities that uses the pH scale to understand the changes in ocean chemistry due to increased carbon dioxide emissions. This module shows that increased ocean acidification has adverse effects on marine organisms.
A set of classroom/laboratory activities to reconstruct Earth’s past climate using isotopic composition data from ice cores and to highlight the influence of orbital forcing and atmospheric carbon dioxide feedback on Earth’s climate.
A model/simulator to understand the prediction of peak global oil production, and to learn about oil as an energy source, its peak and reserves, and the economics and geopolitics of oil.
A classroom/laboratory activity to understand the carbon cycle, and to explore how human activities may affect the natural carbon cycle.
Students will run a simulation to explore how an increase in fossil fuel use will affect the natural carbon cycle, and will discuss the possible impacts on flora and fauna.
Use this tool to help your students find answers to:
- Which components in the carbon cycle act as carbon sinks?
- What are the possible impacts of deforestation on the natural carbon cycle? How might these changes affect the Earth’s climate?
