Associationgame. I give you the word and you tell me any associative words to it.
Beauty, space, fresh, wildlife.
Great. And the next task is to think about the things that can't exist without each other.
Example: People can't live without plants, animals, sunshine, water....
(Animals, plants, the planet.)
Your home task was to write a report based on the idea that we are one family with animals and everything on the Earth. It's time to listen to you.
Основна частина уроку.
We have identified that the world is not only beautiful, but also everything is connected on the Earth. The harmony is the main feature of our life and only if the harmony exists we can live happily. But the situation is not perfect now. Listen to some sayings and tell me what the problem is.
"When the last tree is cut down and the last fish killed, the last river poisoned, then you will see that you can not eat money" (Greenpeace message)
"Look after this planet, it's the only one we have" (Prince Philip of Britain)
"Mother planet is showing us the red warning light – "be careful" – she is saying. To take care of the planet is to take care of our own house." (The Dalai Lama)
And there are many problems that we can't but discuss. We'll need some new vocabulary to do it. First look at the blackboard and pronounce the words after me. And now I give you the cards with the word and its explanation. Try to read and translate the sentences.
Environment is the land, water and air in which people, animals and plants live.
To pollute – to make air, water, soil, etc dangerously dirty.
Pollution is the process of polluting the place.
To cause means to make something happen.
Destruction is the act or process of destroying something.
Shortage is the situation in which there is not enough of something that is needed.
Dump is a place where unwanted waste is taken and left
To dump means to drop or put something somewhere in a careless way.
Waste means things you no longer want.
Poison is a substance that can kill you or make you sick if you eat it, breathe it, etc.
To poison means to make the land, lakes, rivers dangerous by adding harmful chemicals to it.
Nuclear means relating to the central part of an atom.
Weapon is something that you use to fight with.
To survive means to continue to exist.
To endanger means to put someone or something in a dangerous or harmful situation.
Well done! And now I give you only definitions and you say one of the new words which are still on the blackboard.
And now I shall read the text for you. Listen carefully, pay attention at the new words. After listening you will be asked to fill in the spaces with the words.
This word "environment" means simply what is around us. The air we breathe, the soil on which we stand and walk, the water we drink are all parts of the environment. Nowadays we understand that in order to survive people must try to solve the environmental problems that endanger their lives. The most serious environmental problems are:
pollution in its many forms (water pollution, air pollution, nuclear pollution);
noise from cars, planes, trains;
destruction of wildlife and countryside beauty;
shortage of natural resources (water, metals, different kinds of fuel);
the growth of population.
(Underlined words are to be written in the spaces. The blackboard or individual work may be applied).
Now I would like you to work with the tables. If you agree to the statement, write "+", if not, mark it with "– ".
The air is polluted.
There is not enough clean water on the planet now.
The destruction of wildlife is a serious problem.
The soil is poisoned with chemicals.
The cars pollute the atmosphere and endanger people's health.
The nuclear pollution after Chernobyl catastrophe is still essential.
Forests all over the world need protection.
How many pluses have you got? So I understand that you agree with the sayings we have started with.
Well, you've been working hard since the beginning of the lesson. Let's relax and imagine that we are in the forest. It is an early summer. The trees are fresh green. Their shadows protect your faces from the hot sun, but you feel some warm rays on your cheeks. The leaves whisper, the birds sing, the flowers smell so pleasant. You are happy and you enjoy the forest.
And now try to imagine the same forest in 100 years. What has changed? What do you feel and what do you see?
(Pupils tell the class about their images and they usually are pessimistic and dreary.)
In fact it was not an accident that I asked you to think about the forest. Actually it may change in some years. There are many species of animals and plants that are endangered. Some of them are almost extinct. You know that such species are registered in The Red Book. There are plenty that have already disappeared, but some of them can still be saved.
I have prepared some information for you from the electronic Encyclopedia of US. All of you remember one of the symbols of the USA – the bald eagle. But do you know that the bird is almost extinct? Let's see.
(Install the disk, press World Book Encyclopedia, find the word eagle from the list and press OK, page 12, the bald eagle) There you will find the following information.)
The Bald Eagle is not really bald. Its head is covered with white feathers. Its tail is also white. A young eagle is dark brown and has light markings. The Bald Eagle is found only in North America, and is the national bird of the United States. It has been considered an endangered species throughout much of North America since 1960's and 1970's. Until the middle 1900's hunters and trappers killed many bald eagles. The species has been protected by federal law since 1940. The number of bald eagles also dropped because of the pollution of lakes and rivers with pesticides and industrial wastes. Some of these pollutants built up in the bodies of fish that the eagles ate. In most cases the pollutants didn't kill the bird but they affected their ability to reproduce.
(Press reference, main index, US animals and plants index, Eagle, Bald, OK. Here you may find the pictures, the sounds and some information about the bird.)
And as a conclusion of the lesson finish the following sentences.
When the last tree is cut down and the last fish killed, the last river poisoned, then you will see....
Pollution is the process of....
This word "environment" means....
The most serious environmental problems are....
The number of bald eagles also dropped because of....
Домашнє завдання: find the information about other endangered species and write a short report, learn the new words.
