I.T: Good morning, students!
I’m glad to see you!
S-s: Good morning, teacher. We are glad to see you too.
T: Thank you, sit down. Let’s begin our lesson. Who is absent today?
S1: All are present.
II. T: Listen to me attentively.
A) T: At the previous lesson we took the new unit to the theme “Ecology, geography and nature”.
Now, all of you look at the board. We’ll going to see a video. (Students watch video about ecological problems).
T: So, what about the film?
S: About ecological problems.
T:“Ecology” what do you think when you heard this word? Let’s write association for the word “ECOLOGY”. Please.
Environment, pollution, wildlife, nature, ecological problems, etc.
T: Today we’ll speak about our environment, about ecological problems, about wildlife of Kazakhstan. Every thing that’s around us, around you, me all the people; our life, health and health problems. That’s O.k. Let’s clear up:
T: What is Ecology?
P1: Ecology is a science. It is one of the global problems of the 21st century.
P2: Ecology is the science of how living things are related to their environment. The word ecology came from the Greek which means home”. It deals with the protection of environment.
T: What does ecology study?
P2: It studies our environment
T: What does “environment” mean?
P1: All around us is our environment. Environment as it is known is all living and non – living things that surround us.
Polluted air land and water are harmful to plants, animals and people. Many territories, lakes, rivers, seas, oceans and atmosphere are polluted with all kinds of technological, chemical, nuclear and other wastes.
As a result the wide use of national resources upsets the biological balance, pollutes air, water and soil.
People are faced with the problem of environment.
Pollution deprives people of fresh air, clean water, and healthy food. The examples are numerous the waters of Aral Sea are polluted it became much less than some years ago. The Caspian Sea becomes smaller too; people from Semey suffer from radioactivity.
Nowadays people understand how important it is to solve the environmental problems that endanger people`s live.
The most serious environmental problems are: Pollution in its many forms (water pollution, air pollution, nuclear pollution);
Noise form cars, buses, planes, etc. Distraction of wildlife and the beauty of the countryside;
Shortage of natural resources (metals, different kinds of fuel); the growth of population.
such as an environment, to pollute, pollution, to cause, a shortage, a dump, waste, poison, nuclear, to survive, safe.
T: Now, what are the most serious environmental or ecological problems?
P3: Pollution in its many forms (water pollution, air pollution, nuclear pollution, destruction of wild life and countryside beauty; noise from cars, buses, planes, etc.
P4: Shortage of natural resources (metals, different kinds of fuel); the growth of pollution.
Radiation from the sun
Nuclear Power station
Tests of nuclear weapons
T: So, pollution causes different kinds of diseases, Look, it looks like this:
Man Poisoned food
T: Many thanks, you are excellent. So, we are continuing our lesson. I’ll divide you into two groups. Group A and Group B.
Group A- speaking about the problems of Kazakhstan.
Group B- speaking about the problems of the world. So, your tasks are:
I’ll give you 3 minutes for the ready.
Group A- speaking about the problems of Kazakhstan.
P:1. The environment of Kazakhstan has been badly damaged by human activity. Most of the water in Kazakhstan is polluted by industrial effluents, pesticide and fertilizer residue, and, in some places, radioactivity. The most visible damage has been to the Aral Sea, which as recently as the 1970s was larger than any of the Great Lakes of North America save Lake Superior. The sea began to shrink rapidly when sharply increased irrigation and other demands on the only significant tributaries, the Syrdariya and the Amu Darya (the latter reaching the Aral from neighboring Uzbekistan), all but eliminated inflow.
P:2. By 1993 the Aral Sea had lost an estimated 60 percent of its volume, in the process breaking into three unconnected segments. Increasing salinity and reduced habitat have killed the Aral Sea's fish, hence destroying its once-active fishing industry, and the receding shoreline has left the former port of Aral'sk more than sixty kilometers from the water's edge.
P:3. By contrast, the water level of the Caspian Sea has been rising steadily since 1978 for reasons that scientists have not been able to explain fully. At the northern end of the sea, more than a million hectares of land in Atyrau Province have been flooded. Experts estimate that if current rates of increase persist, the coastal city of Atyrau, eighty-eight other population centers, and many of Kazakhstan’s Caspian oil fields could be submerged by 2020.
P:4. With some conspicuous exceptions, lip service has been the primary official response to Kazakhstan’s ecological problems. In February 1989, opposition to Soviet nuclear testing and its ill effects in Kazakhstan led to the creation of one of the republic's largest and most influential grass-roots movements, Nevada-Semipalatinsk, which was founded by Kazak poet and public figure Olzhas Suleymenov. In the first week of the movement's existence, Nevada-Semipalatinsk gathered more than 2 million signatures from Kazakhstanis of all ethnic groups on a petition to Gorbachev demanding the end of nuclear testing in Kazakhstan. After a year of demonstrations and protests, the test ban took effect in 1990. It remained in force in 1996, although in 1995 at least one unexploded device reportedly was still in position near Semey.
Once its major ecological objective was achieved, Nevada-Semipalatinsk made various attempts to broaden into a more general political movement; it has not pursued a broad ecological or "green" agenda. A very small green party, Tagibat, made common cause with the political opposition in the parliament of 1994.
The government has established a Ministry of Ecology and Bioresearches, with a separate administration for radioecology, but the ministry's programs are underfunded and given low priority. In 1994 only 23 percent of budgeted funds were actually allotted to environmental programs. Many official meetings and conferences are held (more than 300 have been devoted to the problem of the Aral Sea alone), but few practical programs have gone into operation. In 1994 the World Bank (see Glossary), the International Monetary Fund (IMF--see Glossary), and the United States Environmental Protection Agency agreed to give Kazakhstan US$62 million to help the country overcome ecological problems.
The most unfavorable ecological action on the Northern Pricaspian territory is connected with development of Karachaganak ski oil-gas-condensate deposit, having high content of sulpharic admixtures, which is often underway with crude violation of nature protection demands. As this takes place, large areas of land are removed from agricultural turnover, thousands of tons of noxious substances, including sculpture dioxide and hydrogen sulphide, are discarded in to atmosphere. Sulphur after purification of oil, storing on the open air, under definite climatic conditions can transform into numerous noxious chemical compounds and produce unfavorable effect on the environment
Group B- speaking about the problems of the world.
P:1. There are several reported cases which have been reported about cutting down of trees, one such a case is Brazil. It’s recorded that in Brazil, the cutting down of trees covers a wide area the size of the state of Nebraska. Moreso the Amazon’s rainforests, forests which are known to be the attraction sites of rain like Zaire, Indonesia, Venezuela and Columbia have recorded a decline in the rain forests which were initially adored.P:2. Global warming also referred to as the greenhouse effect is another environmental problem that is facing the world. This issue has received international attention in today’s world. Several bodies like the government, the scientists and the environmentalist took a lot of concern about the issue because its one of the biggest threats of human beings and organisms. Global warming occurs when the gases get together above the earth surface and make the earth to be like the greenhouse. These gases further trap heat near the surface of the earth thereby threatening the environment. Global warming today is occurring at such a fast rate that is so dangerous because there is a prediction that in the near future the temperatures might rise to higher degrees which may pose a greater problem in the environment. The hurricanes, droughts and floods are some of the possible causes of global warming and environmentalist’s belief that these problems will even be more and worse than these.
The year 2012 cannot be described as the good year for global ecology because environmental problems still continue to grow, not only in number but also in size, pushing this world one step closer to an environmental disaster of gigantic proportions.
Will year 2013 make any difference in this sense? Highly unlikely. The grim economic outlook will receive all the attention from world leaders once again while environmental problems will continue to wait for better times. Environment still continues to be in the shadows of economy.
This situation is an excellent symbol of our entire civilization in which everything is judged primarily by money and material goods while everything else seems to be of very little importance. Environmental condition of our entire planet is constantly deteriorating and yet this doesn't seem to worry world too much- it is like we purposely ignore environmental issues not giving them the importance they most certainly deserve.
Environmental Problems of the World
There are so many problems that face the world today. Many of these problems are attributed however to the environment. Environment is defined as the surrounding that has an influence either externally or internally on the organism. An organism therefore can therefore be affected positively or negatively by the environmental situation. Scientists argue that as globalization continues and the local problems are transformed into issues which affect the international world, there are very slim chances that a society will not be affected. Indeed it’s only a few societies that are untouched by the major environmental problems.
One of the main environmental problems that is evident in today’s world is pollution. There are several forms of pollution that occur in the environmental and therefore they pose a very big threat to the existence of the organisms. One form of pollution is air pollution. Air pollution includes all contaminants that are found in the atmosphere and can either be in form of particles or gases. These substances are considered harmful to an organism because they can cause poisoning or even kill. Sources of air pollution can be human based or natural. In today’s world however, human beings have dominated in producing increasing amounts of pollution since they account for the majority of the pollutants that are released into the air.
VI. Now, let’s summarize the lesson.
What did you get from this lesson?
P1: We’ve got more information about the ecology, environment and environmental problems.
T: O.k. Thank you! As you know, man needs protection. What must we do to solve these ecological problems?
P1: We should stop testing nuclear weapons.
P2: We must plant more trees.
P3: We should clean water and rivers.
P4: We should clear rubbish from lakes and rivers.
P5: We need good filters at nuclear power stations, at factories and plants and also in cars and buses.
T: O.k. Thank you! You’ve made a good conclusion.
We must solve the ecological problems quickly as soon as possible.
If we do such kind of good activities, our world will be very beautiful.
Let’s continue our lesson with the song “The World is Beautiful”
The world is Beautiful.
1. Our world is very-very beautiful
Don’t pollute the air and the land
Everything will be so very wonderful,
If you help the nature every day
Refrain: Let’s keep the world so clean
(2 times) Keep so clean, keep so clean
Never forget to plant
2. Our world is very-very beautiful
Don’t destroy the forests and the grass
Try to keep the land so clean and very nice
For the world is our native land.
Refrain (2 times)
Thank you for your active at the lesson. Your marks for today’s lesson:
Open your diaries and write down your home task:
Write short summary about the ecology of our town Shalkar;
To make up the crossword according to the ecology and environment.
VIII. Now, all of you, stand up.
The lesson is over. You are free. Good-Bye!
S1: The Earth is the only planet in the solar system where there is life. If you look down at the Earth from a plane you will see how wonderful our planet is. You will see blue seas and oceans, rivers and lakes, high snow-capped mountains, green forests and fields. For centuries man lived in harmony with nature until industrialization brought human society into conflict with the natural environment. Today, the contradictions between man and nature have acquired a dramatic character. With the development of civilization man’s interference in nature has increased. Every year the world’s industry pollutes the atmosphere with millions of tons of dust and other harmful substances. The seas and rivers are poisoned with industrial waste, chemical and sewage discharge. People who live in big cities are badly affected by harmful discharge from plants and city transport and by the increasing noise level which is as bad for human health as lack of fresh air and clean water.
S2: Among the most urgent problems are the ozone layer, acid rains, global warming, toxic pollution of atmosphere, disappearance of forests, contamination of underground waters by chemical elements, destruction of soil in some areas, threat to some flora and fauna representatives, etc.
S3: Another important problem is air pollution. Cars and factories pollute the air we use. Their fume also destroys the ozone layer which protects the Earth from the dangerous light of the Sun. Aerosols create large “holes” in the ozone layer round the Earth. Burning coal and oil leads to global warming which may bring about a change in the world’s climate.
