A classroom activity that teaches students about the different atmospheric aerosols and gases released during volcanic eruptions and how they can affect climate.
A classroom/laboratory activity that demonstrates the thermal properties of carbon dioxide (CO2), a greenhouse gas, that may contribute to global warming.
This teaching module allows students to explore the role of stomata in regulating leaf temperature and water loss from plants under different environmental and climatic conditions.
A simple simulator that allows users to change a range of variables such as the color of light, brightness of light, and carbon dioxide concentration, and then note their impact on the photosynthetic efficiency of a plant.
A reading that discusses the effects of elevated CO2 levels on the photosynthetic efficiency of field-grown plants.
A video micro-lecture that describes the phase diagrams of water on Earth, Mars, and Venus. It also describes the water vapor feedback mechanism in the atmospheres of these planets that influences the greenhouse effect.
A set of hands-on classroom and computer-based activities for students to learn about permafrost and to explore various web-based scientific data portals to investigate permafrost distribution, characteristics of permafrost, and the effects of thawing permafrost on the atmosphere and the environment.
A visualization that allows students to explore changes in the pH levels of oceans for different levels of atmospheric CO2. It includes visualizations of CO2 concentrations corresponding to various emission scenarios of the Intergovernmental Panel on Climate Change (IPCC).
A video micro-lecture that explains carbonate buffering in the ocean. It includes discussions on the changes in the chemical composition of the ocean caused by a higher concentration of dissolved CO2, ocean acidification and the resulting effect on ocean biota.
A feature story on a comprehensive report by the World Bank that describes the threat of climate change to poor people and the ways to offset it through adaptation and mitigation strategies.
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.
