ACID RAIN RESEARCH TOPICS Research ACID RAIN RESEARCH TOPICS and present the results to the rest of the class. The presentation may be in the form of an oral or audiovisual class presentation or information display. But, the presentation should contain pictures, graphs/charts and/or video to keep the presentation interesting and captivating. Each presentation should include an explanation of how the topic is related to acid rain. Sources of information may include libraries, newspapers and magazines, internet, television and documentary videos, and interviews or written materials obtained from local utilities or industries. Check out Environment Canada and the Saskatchewan Department of Environment and Public Safety for more information on Acid Rain. Energy Conservation Discover as many ways as possible to conserve energy, which will help reduce acid rain. Investigate how many of these ways are being used in your household, your school, and your community. Conduct a survey to see how many members of your class are using various methods and summarize the results. How could energy conservation be improved? Contact your local power utility for information and for materials that you could use in your presentation. Alternative Energy Sources Explore methods of generating electricity other than burning coal or other fossil fuels that contain sulphur. Examples of alternative energy sources are solar, wind, tidal, hydroelectric, and nuclear power. How does each alternative source affect acid rain? How does it compare to fossil fuels in terms of price, availability, safety, and reliability? What effect does it have on the environment? Make a chart showing the advantages and disadvantages of each method. Is the method being used by the local power utility now? If so, how well is it working? If the method is not being used, are there plans to use it in the future? Reducing Sulphur Oxides Methods of reducing sulphur oxides such as “scrubbers” or using low- sulphur coal should be investigated. Consider effectiveness and cost. Contact the local power utility and any large factories, ore smelters, pulp and paper mills or sour gas processing plants in your area. What methods do they use to reduce sulphur oxides? Cars Of Today Investigate the “three-way catalytic converters” that are used today to reduce nitrogen oxide emissions from cars. What are they? How do they work? How effective are they? Which cars have them? Conduct a survey of car owners (relatives, teachers, and neighbours) to find out if their cars have three-way catalytic converters. If they are not sure, they can find out from their owner’s manual. Show the results of your survey in a graph or chart. Cars Of Tomorrow Many people are trying to develop cars that are less damaging to the environment than today’s cars. These “cars of tomorrow” might use electric batteries, natural gas, alcohol, solar power, or hydrogen as fuel. Investigate these new kinds of cars. How would each of them affect the acid rain problem? How do they compare to the cars of today in terms of cost, safety and efficiency? Contact some of the major car manufacturers to find out about their plans.
