What New Things Are We About to LEARN???????
Standard: SS6G9: The student will discuss the environmental issues in Europe.
What Should You Be Able to do with this Standard??????
-EXPLAIN how acid rain (Germany), air pollution (UK), and nuclear disaster (Ukraine) have impacted European countries.
Note-taking: Create a Flip Booklet
Please listen carefully to my instructions!!!
Environmental Issues In Europe• Acid Rain in Germany• Air Pollution in the United Kingdom• Nuclear Disaster in Chernobyl,
Ukraine
Acid Rain In Germany• is rain, snow, sleet, or other wet
precipitation that is polluted by acids such as sulfuric and nitric acids.
• caused chiefly by burning of coal, gas, and oil by cars, factories, and power plants
Effects of Acid Rain In Germany• harms the environment over large
areas: a) can damage statues, buildings,
and bridges, b) has killed entire fish populations
in lake, & c) can harm forests and soil
Areas Where Acid Rain Is A Major Problem
• Central Europe- Germany is hit particularly hard by this problem because of their large industrial base of their economy.
• Scandinavia• Eastern North America
Pollution ManagementGerman government passed laws to
reduce emissions from automobiles and factories.
• Some factories made devices that remove harmful particles from smokestack emissions, such as filters, by traps that use static electricity, or by devices called scrubbers that wash out particles with chemical sprays.
Checking For Understanding (CFU)Q/A
How has acid rain harmed Germany’s environment??? Explain.
Video Clip: Acid Rain• Please listen attentively to the video.
Also, any additional facts you obtain from the video, write them down in your flipbook.
Air Pollution in the United Kingdom• Smog is a form of air pollution• first used in 1905 to describe the
combination of smoke and thick fog that at times hung over London and other cities in the United Kingdom
• also refers to a condition caused by the action of sunlight on the exhaust gases from automobiles and factories
Effects of Smog• Can kill or make sick
(About 4,000 Londoners died within five days as a result of a thick smog in 1952)
• destroys plant life• causes building
materials to deteriorate faster than usual
London-Type Smog• occurs when moisture condenses
with smoke produced by the burning of coal
• forms smog droplets• sulfur dioxide is in air in London--
attacks the lungs and makes breathing difficult (called sulfur smog)
What is Being Done to Reduce Air Pollution in the
UK????The Uk has been working hard to
reduce air pollution since the Great London Smog occurred.
The government has:– tightened emissions standards for
vehicles, – endorsed the use of cleaner fuels, and – urged citizens to use public
transportation like buses and subway systems.
CFUStand-Up/Sit Down
• If you think the statement below is true, stand up. If you think the statement is false, stay seated.
The term smog is a derived from the words smoke and fog.
Video Clip: Air Pollution• Please listen attentively to the video.
Also, any additional facts you obtain from the video, write them down in your flipbook.
Chernobyl Disaster in the Ukraine
• the worst nuclear accident in history• April 26, 1986• Chernobyl nuclear power station in
Ukraine (then part of the Soviet Union)
• caused numerous deaths and injuries • widespread environmental
contamination
Note: In the 1980’s many countries were using nuclear power. Nuclear power plants were producing cheaper energy without filling the air with pollution and without using up Earth’s supply of fossil fuels.
How Did The Disaster Happen?• had four nuclear reactors (devices that produce and control
nuclear energy) in service
• operators shut off several safety systems and began to power down the fourth reactor for a test of the plant’s emergency electrical power supply
• power surge caused fuel in the reactor to overheat, which caused an explosion and fire
• produced a radioactive cloud more than 3,280 feet in height
• radioactive substances spread over parts of what are now Ukraine, Russia, and Belarus
• Air Currents/Winds carried the radioactive material into northern and central Europe.
Radiation Found In the Ground After Chernobyl Disaster
The Cover-Up• Soviet leaders concealed the
accident from the public for nearly two days and refused outside help
• Eventually, nearby towns were evacuated
• Cleanup workers covered the reactor with a concrete shell
Effects of Chernobyl Disaster
• 31 people reportedly died from radiation sickness or burns
• more than 200 others were seriously injured
• Fallout (radioactive material) from the accident caused a number of health and environmental problems
• increased rate of cancer, skin diseases, respiratory ailments, and heart problems
CFU: Q/AIn your own words, explain how the
nuclear disaster happened in Chernobyl, Ukraine.
Video Clip: Nuclear Disaster• Please listen attentively to the video.
Also, any additional facts you obtain from the video, write them down in your flipbook on the back cover (additional notes).
