Вступительное слово учителя (приветствие, сообщение темы и цели урока);
Teacher: Good morning, boys and girls! I am glad to see you. Sit down, please. I hope you are okay today and ready to work hard and enthusiastically. Today we have our lesson on the topic “Environmental Problems”.
Its a wonderful world we live in. It is our Earth. For thousands of years the Earth has given support to all forms of life human beings, animals, birds, fishes, insects and plants. But now people all over the world think about our planet. They think about air, water, plants and animals on the Earth. They say our planet is in danger. We have very serious environmental problems on our Earth. Who can say what these problems are?
P1: One of the problems is air pollution.
P2: I think the next global problem is water pollution.
P3: A lot of animals, birds and plants are disappearing now. To my mind its a very serious problem.
P4: Another problem is overpopulation. Nowadays there are too many people on the Earth, so the pollution of it becomes higher and higher.
P5: And we have also such a problem as destruction of natural recourses. For example, every year more and more trees are cut down.
T: You are quite right. At this lesson we are going to discuss these global environmental problems as air and water pollution, endangered animals and plants, and secondly we will try to answer the question: “What can we do to protect our environment and to save our planet?”.
2. Фонетическая зарядка (на слайде написана активная лексика).
T: First of all we will review some words and word combinations on this theme.
to protect the environment
to be polluted by
to be strictly prohibited
to drop litter
to clear litter away
to throw away
to be in (out of) danger
to avoid doing smth.
(Работа проводится в режиме T class; P1 P2 P3 P4 (в группах); T P1, P2, P3, P4).
3. Проверка знания слов.
T: I am sure that everybody knows the meanings of these words. So you can easily do the next task. Match the words with their definitions. We shall do this work in groups.
a) A gas in the atmosphere. The gas that we breathe out.
b) The Earth is becoming warmer because there is too much carbon dioxide in the atmosphere.
c) The study of living creatures and plants in their surroundings.
d) This is the atmosphere between 10 km and 60 km above the Earth. The ozone stops a lot of the ultraviolet radiation from the sun.
е) When the land, sea or air becomes dirty or poisonous.
f) Part of sunlight.
7. Carbon dioxide
g) The natural living place of an animal or plant.

9. Ozone layer
i) It means simply what is around us.
10. Ultraviolet radiation
j) All the plants that grow in a region.
11. Acid rain
k) The animals of a region.
T: Ready? Lets check.
4. Выступление учащихся со своими проектами. Обсуждение экологической ситуации.
T: As you remember your homework was to make projects on the problems of our environment.
So we have four groups. Each group has prepared a project.
These are the themes of the project:
1. Air pollution.
2. Water pollution.
3. Animals are in danger.
4. Plants are in danger.
5. Land pollution.
After listening to other groups, you can ask questions, add some information or express your opinion.
Okay, lets start with air pollution.
P1: Air pollution is a very serious problem. Factories emit tons of harmful chemicals. These emissions have disastrous consequences for our planet. They are the main reason for the green house effect and acid rains.
P2: When the Americans decided to clean up the Statue of Liberty in 1986, the first thing they had to do was to make a hole in her nose and take away the acid rain that had collected inside. The polluted air of New York had mixed with the rain and damaged the Statue badly. And you certainly know that most of the pollution in big cities comes from cars and buses.
P3: An even greater threat are nuclear power stations. We all know how tragic the consequences of the Chernobyl disaster are. Nuclear pollution can not be seen but its effects can be terrible.
P4: More and more often people are told not to be in direct sunlight because ultraviolet radiation from the sun can cause skin cancer. Normally the ozone layer in the atmosphere protects us from such radiation, but if there are holes in the ozone layer ultraviolet radiation can get to the earth. Many scientists think that these holes are the result of air pollution.
T: Have you got any questions? What is your opinion on this problem?
(ученики высказывают свое мнение, задают вопросы).
T: Lets continue speaking. The next theme is water pollution.
P5:Water is very important for life on the Earth. It is in oceans, seas, rivers and lakes. There is much water on our planet and at the same time there is little water on it. It is so because very little water on the Earth is good for drinking. In many rivers and lakes water is very dirty. Sometimes people cannot swim even in the sea because the sea and the seaside are not clean. In many places water is not drinkable. It is dangerous to use it when you cook. Even fish die in such water.
P6: For example Lake Baikal is the deepest fresh water lake on the Earth. It is 1741 metres deep. The lake is very beautiful but now it is in great danger, because of the factories which are near it. At some places the water in the lake is so dirty that it can kill animals and plants in the Baikal and near it.
P7: There is no ocean or sea which is not used as a dump. The Pacific Ocean, especially, has suffered from nuclear pollution because the French Government tests nuclear weapons there. Many seas are used for dumping industrial and nuclear waste. Britain alone dumps 250,000 tons of industrial waste straight into the North Sea. This poisons and kills fish and sea animals. Nuclear-poisoned fish can be eaten by people.
P8: Many rivers and lakes are poisoned too. Fish and reptiles cant live in them. There is not enough oxygen in the water. In such places all the birds leave their habitats and many plants die. If people drink this water they can die too. It happens so because factories and plants produce a lot of waste and pour it into rivers. So they poison the water.
T: So weve understood that air and water pollution are the most important problems on our planet. And what do you think what we can do to save our planet from air and water pollution?
P1: I think to make air clean we need good filters at nuclear power stations, at factories and plants and also in cars and buses.
P2: To my mind we can walk or use a bicycle instead of going by car. We should clear rubbish from lakes and rivers.
P3: Factories and plants must be forbidden to pour their waste into rivers, lakes and oceans.
T: The next problem is connected with the animals which need our protection. Now we will listen to the next group about some endangered animals. As for the other groups, be ready to add some more facts on this problem.
P9: Many animals and birds are disappearing nowadays. Many of them are in danger. Have you ever seen dodo? No, you havent. The last of these large birds that couldnt fly died many years ago. Now it is extinct. We even say “as dead as a dodo”, which means “finished”. Your great-grandparents may just have seen a passenger pigeon: the last one died in 1914. A lot more endangered species fish, reptiles, insects, birds, mammals may disappear too. The reason is Man that kills animals and destroys their habitats.
P10: Indian tigers are among the endangered animals. Tigers are the biggest cats in the world. They are skillful hunters. Often they are dangerous. Some people are afraid of tigers and kill them to save their livestock and their lives. But some people have hunted tigers for fun and for their beautiful skin. They sell the skin and get a lot of money. There are few Indian tigers on the Earth now. Many of them are usually old and sick animals. Most tigers hide from people in deep, dark forests. The question is “Have those animals got a future?”
P11: We can ask the same question about African elephants. They are wonderful animals. They can help men. Today many elephants in Africa are dying because they do not have enough to eat or to drink and because they do not have enough space to live in. Hunters kill thousands of elephants every year. Some kill them for meat. But most kill elephants for their tasks. Specialists think that only two million elephants live on the planet today.
P12: I want to say a few words about Blue whales. They are the largest animals ever to have lived on the Earth. More than 200,000 blue whales used to live in the Atlantic and Pacific oceans. Today there are only about 600 to 3,000. Why? Since the 17th century they have been killed by hunters for their oil and meat. They have been protected by international law since 1967.
T: Well, we have learned about several animals which are almost instinct. Can you add anything?
P1: I want to add that as for the other animals the situation is the same: 8 big cats are killed to make one fur coat.
P2: Only several hundred of rhinos are left in Asia and about 3 million kangaroos are hunted every year.
P3: Over 400 000 monkeys are caught every year and about 300 dolphins and 30 sea turtles are poisoned by water pollution everyday.
T: Not only people can speak about the problems of environment. Books can speak, too. There is a kind of book which screams. Its the Red Data Book. Its a reference book on rare and disappearing animals and plants. Why is it “Red”? The color red is a danger signal, understandable to all people in the world.
Not only animals are in danger. It also concerns plants. We will learn about it from the last group.
T: It was very interesting to listen to all of you. You have done very informative projects. Thank you very much. You are tired a bit, arent you? Why not relax a little? I hope youll enjoy listening to wonderful music from the TV program “In the world of animals”. (ученики смотрят и слушают видеоклип из ТВ-программы «В мире животных»).
6. Обсуждение экологических проблем в своем поселке.
T: Lets pass to the problems closer to us. Problems devoted to the ecology of our settlement Ibresi. Our settlement is situated in a beautiful place. It is surrounded by forests and rivers. People like to spend their free time fishing, gathering mushrooms and berries, having picnics and lighting barbecues. Youll see some pictures of well-known places. (Просмотр слайдов с видами поселка).
T: Do you like our settlement? Why?
T: But there are some ecological problems in our area. What are they? What can you say about it?
P1: We see different kinds of trees and flowers in the meadows near our settlement. But today they are disappearing. We shouldnt pick wild flowers in the meadows and forests.
P2: People cut down trees. Fires are started. If trees are destroyed and people pick flowers and grass birds and animals may become extinct. We mustnt harm plants.
P3: We throw away too much and in the wrong place. We leave litter near the river. The water is polluted and the fish in the river die. Our river Chernorechka is polluted too.
P4: We have a beautiful pond in the forest. We call it Pitsunda. A lot of people swim in this pond in summer. But the water is not clean there. As for our settlement there isnt clean water to swim. I am worried about it.
P5: A lot of cars have appeared in our settlement recently. The air becomes dirty in the streets.
P6: Every spring I see a lot of rubbish in our settlement. We, school children, try to do our best to clean the streets. Every class organizes a clean-up day once a month.
T: So we see, there are a lot of ecological problems in our area. Of course, we cant solve all of them ourselves, but we can do our share to keep the Earth clean. And what do you personally do to keep the Earth clean?
P1: I dont throw litter in public places.
P2: I plant a tree every year in the garden.
P3: I never break glass bottles.
P4: I dont cut wild flowers.
P5: I take part in a clean-up day once a month.
P6: I plant flowers in the garden.
P7: I save water.
T: I see you understand the ecological problems of our area. It is also seen from your pictures. All of you have done well.
8. Домашнее задание: Рассказать об экологических проблемах нашего поселка и что мы можем делать чтобы решить их.
9. Подведение итогов.
1. Выставление оценок.
2. T: Today we tried to summarize our knowledge on the topic “Environmental Problems” and to find out some ways how to save our planet Earth. I believe youll never pollute the environment, the place where you live.
A famous Russian writer Mihail Prishvin said: “To protect nature means to protect our motherland”. I hope you will keep these words in your heart. And at the end we shall sing the song “Save Our Planet”.
Save Our Planet
Theres so much pollution
Poisoning the air
There is so much litter
We can see it everywhere
While everyone stands by
The world we love is dying
And were the
Why are we killing the world
Why arent we doing our share
We can save our planet
We can help it survive
Al it needs is a little care
If we all work together
Something can be done
We need a clean-up campaign
Which involves everyone
We can slow down global warming
We can stop the acid rain
We can heal our planet
We can help it live again
Why are we killing the world…….
If we dont act quickly
Our world will soon be dead
We must leave our cars at home
And use bicycles instead
We must stop using chemicals
And burning fossil fuels
We must recycle all our mess
Its easy to do
We must stop killing the world
We must start doing our share
We can save our planet
We can help it survive
Al it needs is a little care
