Why Lesson Planet?
Chemistry and earth science meet in a lesson plan on carbon dioxide emissions. After reading about atmospheric problems caused by using fossil fuels, science stars balance equations for the burning of different alkanes. They compute the number of moles of gasses emitted and consider the use of photovoltaics and other clean energy sources. Although it is only a paper and pencil assignment, it is well-written and pertinent when you want to open your chemists' eyes to the threat of climate change.
