Pullutey Judy

Air Pollution

Cars, trucks, factories, power plants, trains, and planes create harmful gases that make the air dirty. When gases make the air dirty this is called air pollution. We measure air pollution in pounds, with 0.97 pounds of air pollution = 1 mile of driving.

Pollutey Judy loves to drive! She drive everywhere, even places that are close enough to walk.

Pollutey Judy never rides her bicycle, never carpools, and never takes the bus. She thinks driving is so convenient!

Pollutey Judy drives by herself every day. The chart below shows a typical day in Pollutey Judy’s life. Calculate how much daily air pollution Pollutey Judy’s driving produces. Round answers to the hundredths place.

Destination	Distance (round trip)	Mode of Transport	Air Pollution
Work	4.3 miles	Driving
Coffee Shop	1.2 miles	Driving
Friend’s House	5.8 miles	Driving
Home	0.6 miles	Driving

�Hand out Go on a Pollution Diet! worksheet. Tell students that Judy has other� transportation options: she can walk, bicycle, carpool, or take public transportation. Review the chart at the top of the Go on a Pollution Diet! worksheet. Briefly review the pros and cons of each transportation option.�
�Have students complete the Go on a Pollution Diet! worksheet. After they have finished, call the class back together. Ask students to share how they reduced the amount of air pollution that Judy produced. Pick one student’s pollution diet and work together to calculate how much air pollution Pollutey Judy will produce when she stays on that diet for one week, one month, and one year. Compare these computations to the amount of pollution Judy’s driving currently produces per week, month, and year. �
