Accessed September 18, 2006. Discuss how sewage is related to eutrophication, biochemical oxygen demand (BOD), and dissolved oxygen. Identify the purpose and goals of the Clean Air Act Amendments (CAAA) of 1990. (5 minutes) ACTIVITY 1: Cornering Air Quality 1. Principles of Environmental Education 3. CC BY-SA 3.0. http://en.wikipedia.org/wiki/Air_pollution (2) Define species diversity including species richness and relative abundance. cyclone: A pollutant recovery method in which dust-laden gas is whirled very rapidly inside a cylinder-shaped collector. In the ASN, standards are hierarchically structured: first by source; e.g., by state; within source by type; e.g., science or mathematics; Students observe and discuss a simple model of a wet scrubber to understand how this pollutant recovery method functions in cleaning industrial air pollution. It's a problem all over the world! Free K-12 standards-aligned STEM curriculum for educators everywhere. Learning Objectives. Environmental engineering is a newer engineering discipline, growing out of civil and chemical engineering. The most common methods of eliminating or reducing pollutants to an acceptable level are: destroying the pollutant by thermal or catalytic combustion (burning the air), changing the pollutant to a less toxic form or collecting the pollution with equipment to prevent its escape into the atmosphere.

Decreased stratospheric ozone: a depletion in ozone levels caused by the release of refrigerants, which produce free radicals that catalyze the decomposition of ozone. Major pollutants include particulate matter, ozone, sulfur dioxides, and nitrogen dioxide. Explain to the students that in this lesson they will investigate four air pollution cleaning methods developed by environmental engineers and used in industry: scrubbers, electrostatic precipitators, cyclones and baghouses. It also aims to increase global warming, affect climate change and deplete the ozone layer. Conduct the literacy activity, What's a Kid to Do? Heavy dirt particles fall out and are removed, and smaller particles are trapped by filters (bags) made of cloth, paper or similar materials. In this lesson, students take on the role of engineers and experiment with four different methods for cleaning up industrially-polluted air. Learning Objectives ... reusable cloth shopping bags with artistic educational messaging to spread the word about the need to reduce plastic pollution. Have them raise their hands to respond. There are also a number of natural ways to clean the air, including: To help reduce air pollution, over the years, our government has passed many laws, called the Clean Air Act. Sometimes the mist is injected with limestone powder to help extract the dirt particles. Course Outcome: • Understanding of air/water pollution regulations and their scientific basis • Apply knowledge for the protection and improvement of … Originally found at: http://www.tceq.state.tx.us/assets/public/assistance/education/air/air_pollution_control.pdf, Section 6 Particulate Matter Controls, U.S. Environmental Protection Agency. The contents of this digital library curriculum were developed under a grant from the Fund for the Improvement of Postsecondary Education (FIPSE), U.S. Department of Education and National Science Foundation GK-12 grant no. The U.S. Environmental Protection Agency (EPA) sets national standards for each of the criteria pollutants, and the states must take action to ensure the standards are met. Air Pollution Control. Give examples of when the use of a scrubber, an electrostatic precipitator, a cyclone or a … i.e., most hands-on activities are part of lessons, lessons are grouped into multiday baghouse: A pollutant recovery method that works very much like a giant vacuum cleaner. List and briefly describe eight categories of water pollutants. Describe and explain how a scrubber, an electrostatic precipitator, a cyclone and a baghouse work as pollutant recovery methods.
