This video is from the Energy 101 video series. It explains the process for converting micro-algae into fuel and makes the case that algae-based biofuels hold enormous potential for helping reduce our dependence on imported oil.
This video features CU Boulder Professor Jeff Mitton and his research team, who study the effects of mountain pine beetle infestations on the forest ecology in the Rocky Mountains. They explain the pine beetle life cycle and how they attack trees. An outlook into the future is also provided.
This video explores the work of environmentalist John Hart, a Professor of Environmental Science at U.C. Berkley. In the Rocky Mountains of Colorado, Dr. Hart has established an experimental laboratory in which he has artificially created and maintained a 3-degree increase in surface temperature of a plot of land, and documented the impact on plant species occupying the plot.
With this carbon/temperature interactive model, students investigate the role of atmospheric carbon in the greenhouse effect using a relationship between atmospheric carbon dioxide and global temperature.
This Energy Flow Charts website is a set of energy Sankey diagrams or flow charts for 136 countries constructed from data maintained by the International Energy Agency (IEA) and reflects the energy use patterns for 2007.
In this activity students make biodiesel from waste vegetable oil and develop a presentation based on their lab experience. Parts of the activity include creation of bio-diesel from clean vegetable oil, creation of bio-diesel from waste vegetable oil, chemical analysis of biodiesel, purification of biodiesel, and creation of soap from glycerin.
This beautifully filmed and produced video describes the changes that global warming is already bringing to Northern Canada and Greenland. Local people describe changes to ecosystems, impacts on culture and life styles, and the challenges of melting permafrost. Ship captains describe changes in navigational channels and fjords. Scientists describe changes in albedo and permafrost, as well as increased pollution transported from outside the Arctic (the Grasshopper effect).
In this activity, students compare carbon dioxide (CO2) data from Mauna Loa Observatory, Barrow (Alaska), and the South Pole over the past 40 years to help them better understand what controls atmospheric carbon dioxide. This activity makes extensive use of Excel.
Students conduct an energy audit to determine how much carbon dioxide their family is releasing into the atmosphere and then make recommendations for minimizing their family's carbon footprint. Students are specifically asked to understand the units of power and energy to determine the cost of running various household appliances. Finding the amount of carbon dioxide emitted for different types of energy and determining ways of reducing carbon dioxide output is the outcome of the lesson.
