Air Pollution Assignment: The average person breaths 35lbs of air each day. Yet in the USA we pollute our air with over 200,000,000 tons of “aerial garbage” each year from industrial smoke wastes, auto emissions, incinerators, etc. This dirty air costs us over $12 billion a year, but it is more than a costly nuisance. Dirty air shortens our lives by contributing to lung diseases; it ruins vegetation; causes paint to peel and discolor; corrodes metals, and wastes fuel. Air pollution can be minimized if people know the problem and work to control it.

Air pollutants are:  Solids such as dust, soil, soot  Gases such as sulphur dioxide and carbon monoxide  Aerosols such as pesticides and chemicals

Materials Needed: Pencil and paper paper waxed paper stapler heavy cardboard Vaseline

Instructions: 1. Cut a piece of waxed paper into 2 ½” squares and staple to heavy cardboard 2. Coat the waxed paper with a thin layer of Vaseline. 3. Place the papers in various location where they can remain undisturbed for a week. The classroom, cafeteria, grounds, student backyard, a local sotre or the bumper of a car. 4. At the end of the week collect all the papers carefully and examine them with a magnifying glass to see which received the most pollution. a) Try to identify dust, pollen, ash, spores, soil, and other particles. b) Which was the most common type found? c) Which location attracted the most particles? Why? 5. Organize all data into a chart showing date placed, date collected, location, amount of accumulation, possible cause of pollution and reason for variance. 6. Display chart in area designated by teacher.

Evaluation: We will use the following rubrics: 1. Name and hour in upper right corner 2. Lab completed and data analysis completed. 3. If you can follow written directions, complete the work and show creativity and thought process for the work assigned.

Remember: The Process is as important as the product. On this assignment I’ll be looking to see if :  you can follow written directions  complete the work fully  show creativity and thought process in work assigned
