In this activity, students plant, care for, and observe the changes in plants growing under conditions of ambient (normal) CO2 (carbon dioxide) and increased levels of CO2. Students learn about the relationships among CO2, plants, and climate change.
In this video segment from NOVA's Saved By the Sun hour-long video, students learn about photovoltaics and see how two families are using solar technologies in their homes. The video introduces the ideas of state incentives and net metering benefits.
This video features changes in the land, sea, and animals that are being observed by the residents of Sachs Harbour, Northwest Territories, Canada many of whom hunt, trap, and fishbecause of their long-standing and intimate connection with their ecosystem. Scientists interview the residents and record their observations in order to deepen our understanding of climate change in the polar region. Background essay and discussion questions are included.
This is a laboratory activity in which students will compare the amount of carbon dioxide in four different sources of gas and determine the carbon dioxide contribution from automobiles. They test ambient air, human exhalation, automobile exhaust, and nearly pure carbon dioxide from a vinegar/baking soda mixture.
In this activity students use a series of Landsat images from 1975 to 2005 to examine changes in land cover and abundance of vegetation in the summer (peak abundance) and relate these changes to climate conditions.
This video illustrates how atmospheric particles, or aerosols (such as black carbon, sulfates, dust, fog), can affect the energy balance of Earth regionally, and the implications for surface temperature warming and cooling.
