|FIELD: Earth Science||DURATION: 1.5 hrs|
|OBJECTIVE: Students will measure the amount of pollutants emitted by cars and calculate the total pollution near their school.|
|METHOD: Students measure the weight of exhaust emissions and calculate the total pollution from all cars on the road.|
|KEY VOCABULARY: Pollution, exhaust.||GROUP SIZE: Any|
Air pollution comes in many forms. One of the most obvious forms is from the exhaust pipe of automobiles. Car exhaust has a variety of chemicals in it. The diagram is a display of the chemicals in a typical exhaust and their relative amounts.
Some of the deadliest chemicals to humans found in car exhaust are carbon monoxide, nitrogen oxides, and ozone-producing chemicals like hydrocarbons.
In this experiment you directly measure total car exhaust weight and calculate long term amounts over time.
