Introduction

Population growth in Pennsylvania has been staggering over the last few years. The population has grown so rapidly, that the existing power plants cannot meet the current demands for electricity. Blackouts and brownouts have been common occurrences in many Pennsylvania communities recently. The Mega Watt Power Company is considering a site 5 miles west of Landisville as a possible location for a coal burning power plant. This plant will provide over 250 badly needed jobs to local residents. In addition, the plant will increase the local tax base significantly.

Along with all of the positive benefits a new industry would bring to the area, are some possible negative effects. Emissions from power plants can lead to an increase in air pollution, which in turn, can cause acid rain. In this activity, teams of students will become scientific experts and do research on the effects of acid rain on both living organisms and non-living objects. The team of experts will then approach the township commissioners with their findings and their decision as to whether or not the plant should be built.

 Task

Your task is to thoroughly research the topic of acid rain. You, along with the other experts on your team, are responsible for providing information to the township commissioners so that they can make an informed decision as to whether or not to build the electric utility plant. While conducting your research, keep in mind the positive benefits a large industry would bring to a community. (jobs and money)

Through your research, you will identify what acid rain is, and how and why it forms. You will also determine the effects of acid rain on a variety of living organisms, as well as man-made materials. In addition, you will identify methods that are effective in reducing acid rain, and costs involved in doing so.

Finally, you will organize your data and make a group decision as to whether or not to build the plant. This decision, along with your findings, will be presented to the township commissioners at their next meeting. Remember, you and your team of experts, alone, are responsible for providing clear, and concise information that will lead the township commissioners to the best decision for the community.

Each scientific expert will take part in the presentation and will be responsible for:

 Process

Your team will consist of four experts; an ecologist, an environmental engineer, a pollution control engineer, and an environmental lawyer. Each person on your team should choose one of these occupations. Once the roles have been established, begin research using the links provided in the resources section. Each expert is responsible for answering all questions listed for that particular area of study.

 

Expert

Questions to be Answered

 

 Ecologist

Environmental Engineer

 

 

  • What is acid rain?
  • What causes acid rain?
  • How does acid rain form?
  • What is the history of acid rain?
  • What are the major problem areas in the US?

 

Pollution Control

Engineer

 

 

  • What are natural and man-made sources of acid rain?
  • What steps can be taken to reduce acid rain?
  • What costs are involved in the reduction of acid rain?
  • What are some alternative energy sources?

 

 

Environmental Lawyer

 

 

 

  • What current legislation exists to reduce acid rain?
  • What new laws or amendments have been recently proposed?
  • What are some benefits that an electric utility company will bring to the community? (in addition to jobs and taxes)
  • What are the economic losses due to acid rain?

  Conclusion

At the completion of this project, you will have a much better understanding of the acid rain problem. You will understand the basic causes of acid rain, and why some areas of the country have a high incidence of acid rain, and other areas have little or no problem. Your team will have already worked through the project and you will be aware of the controversial issues surrounding the acid rain problem. You will understand the effects of acid rain on living and non-living things and why, even though we benefit tremendously from the electricity generated by power companies, there is a downside to this luxury that is called acid rain, and it cannot be ignored. Lastly, at the completion of this project, you will be able to list steps that can be taken to reduce the amount of acid rain, and identify some alternative energy sources.
