Document Sample

 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
