Students measure the weight of exhaust emissions and calculate the total pollution from all cars on the road.
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.
