In this lab activity students generate their own biomass gases by heating wood pellets or wood splints in a test tube. They collect the resulting gases and use the gas to roast a marshmallow. Students also evaluate which biomass fuel is the best by their own criteria or by examining the volume of gas produced by each type of fuel.
This animated video outlines Earth's energy. The video presents a progression from identifying the different energy systems to the differences between external and internal energy sources and how that energy is cycled and used.
This video shows where and how ice cores are extracted from the West Antarctic Ice Sheet (WAIS), cut, packaged, flown to the ice core storage facility in Denver, further sliced into samples, and shipped to labs all over the world where scientists use them to study indicators of climate change from the past.
This video and accompanying essay examine carbon capture and storage and clean-coal technology, providing statistics for overall annual U.S. consumption as well as average household usage. Turning solid coal into a clean-burning fuel gas (syngas) and capture and storage pros and cons are discussed.
This is an interactive webtool that allows the user to choose a state or country and both assess how climate has changed over time and project what future changes are predicted to occur in a given area.
In this activity, students will determine the environmental effects of existing cars and a fleet consisting of their dream cars. They compute how many tons of heat-trapping gases are produced each year, how much it costs to fuel the cars, and related information. Then, students research and prepare a report about greener transportation choices.
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.
