This unit links the physical and chemical properties of atmospheric pollutants and tetraethyllead to the controversial decisions made in the early years of the automotive age.
The Questions: How did lead compounds, whose extreme toxicity were known for more than a century before they were introduced into gasoline, become an accepted and everyday component of the fuels we use - and of the air we breathe and the ground upon which we walk?
Students will go through a series of units outlined in the concept map and end with a case discussion on how automakers, oil companies and the government might have better dealt with the issues of gasoline quality in the early 20th century.
Begin with the unit on the the story of 1. Charles Kettering, Thomas Midgley and Tetraethyllead or click on any area of the concept map below.
