The rocks and the mountains, The rivers that blow, The rain and the sunshine, The ice and the snow.
3. Вчитель Listening. “Nature Is Full Of Wonders”
We live in a magic world. The world is full of wonderful things. It is our nature. Nature gives us life. Nature is our best and kindest friend. Nature teaches us to be kind and clever, attentive and creative. It teaches us to understand the world around us. We see the blue sky and the grey rain, the black night and the shiny stars, green mountains, seas and sunshine.
Nature presents us with beautiful songs. They are the songs of the woods, the songs of the wind, the songs of birds, the songs of the rain. Nature shows us wonderful pictures of different colours: the blue sky and the green grass, the white snow and the black night, the red poppy and the yellow sunflower. Nature is a great artist and poet. It has different colours for each season. Autumn is yellow, winter is white, spring is green, summer is bright.
We are the happiest people because we are face to face witn nature. It is nice to walk in the forest and listen to the buzzing of bees, the whisper of the wind, the trees and the flowers. Our first spaceman Y. Gagarin said: “How beautiful our blue planet is. How small it is. People of the world, take care of it, protect it”.
Здоров’язберігаюча хвилинка (звукотерапія та кольоротерапія) Вчитель пропонує послухати звуки природи й переглянути відеоролик про красу природи.

The Greenhouse Effect A greenhouse is a building made of glass where you can grow flowers and other plants that needs a lot of warmth. How it works. The sun shines in through the glass and warms the greenhouse, and the roof and walls keep the heat from getting out. Our greenhouse. The Earth is surrounded by a blanket of gasses. The gas named carbon dioxide acts like a greenhouse. The sun shines in and the blanket of gasses traps the heat like a roof, keeping it close to the planet. That’s good. We can not live without warmth. What is going on. Factories , electric power plants and cars are making a lot of gasses. These new gases are trapping more and more of the sun’s heat. This is called greenhouse effect or global warming. What can happen. If the Earth’s temperature gets hotter by just a few degrees it could change the weather all over the world in big ways. Places that are warm would become too hot to live in, and places that are cold would become warm.
Acid Rain Up in the sky. When we look up, we see clouds and the blue sky. But there are other things in the sky that we don’t see. Some of these are harmful to the Earth.
What happens. When power plants burn coal to make electricity, and when cars burn gasoline, invisible gases are released into the air. Some of these gases can mix rain or snow and make it acidic, like lemon juice or vinegar. This is called acid rain.
Bad news. Acid rain is extremely harmful to plants, rivers and lakes, and the creatures that live in them. In some places it is killing forests. And it pollutes the water that animals and people need to drink.
Our mission. It is very important for us to stop making acid rain. One good way is to drive our cars less. Another good way is to save energy. The less energy we use, the less fuel these power plants have to burn. Industrial countries should control their level of pollution. This is already happening in some parts of Europe. There are several countries (‘The 30% Club’) which have cut their acid rain pollution by 30%.
Water pollution
The planet Earth is mostly water. Oceans cover the biggest part of it – there are lakes, rivers, streams and even underground water. All forms of life on the Earth cannot exist without water. It is precious. Are we doing a good job on keeping it clean? In many places water has become polluted. Rivers and lakes become polluted by garbage or bumped poisonous chemicals. Underground water can be polluted by gasoline, harmful liquids, some fertilizers and pesticides. These leak down through the ground.
Seas and oceans have become a dumping place for garbage and poisonous chemicals. They have become so polluted from oil spills and factory wastes that the fish are dying and other living resources of the sea are coming to an end. This subsequently affects people who depend on sea food. Nature reserves of pure water are decreasing. We must save our water, keep it clean so that people, plants, animals and fish will always have a life source. We must do our best to protect seas, rivers and lakes from further pollution.
Air pollution The old days. Until about 100 years ago the air was clean – perfect for the people and animal to breathe. Factories. Then people started building factories. The factories and cars put a lot of harmfull gases into the air. Then people started driving cars, which added more pollution to the air. Today tha air is so polluted that it is not always safe to breathe. Many cities around the world have air filled with a pollution called “smog”. This is so strong in some places that the air which should be blue, actually looks brown. Polluted air is not only bad for people and animals, but for trees and other plants as well. So it is very important for us to clean up the air we all breathe.
Urban Problems The urban problem is one of the most complex today. One of every six people lives in a city with population of more than one million. There is a tendency towards rise in the population of cities. Today there are a lot of big cities in the world with the population ranging from 5 to 10 million and above. The problems arising as a result of this are water supply, public transport, unemployment, food, air pollution, noise.
Too Much Garbage! When we throw something away it goes in a garbage can. Once a week a garbage truck and the can is emptied. But what do you think happens to the garbage then? Does it just disappear? No way! What happens. Almost all garbage is taken to a garbage dump or land fill, where the garbage truck empties on the ground. After the truck leaves, a big tractor comes along and pushes dirt on top of the garbage. Now we are making so much garbage that in many places there is not enough room for it. We can recycle(re-use) materials instead of throwing them away. This way we’ll produce a lot less garbage and help keep our planet clean.
5. Опрацювання документа конференції: «Декларація взаємозалежності людини та природи». Every conference usually ends with a document. We’ve worked out a document of our conference. Іt is "A Declaration of Interdependence".
The Declaration of Interdependence
1) Factory owners and businessmen managing enterprises harmful for environment first of all must provide powerful filters to reduce smoke, dust and dangerous gases to make air cleaner.
2) Special kinds of fuel for cars and more efficient engines can help to decrease air pollution.
3) We must do our best to protect seas, rivers and lakes from further pollution.
4) Our factories and plants have to stop throwing wastes of their processes into the water.
5) Waste-free technologies must be developed and used in the production process.
6) Stop making acid rain.
7) Drive cars less, walk instead of driving.
6. Speaking. Let’s discuss. We are pupils .
Make a list of practical ways how we can help the nature.
- We should plant the trees;
- we should swich of the lights when we leave the room;
- we can rycycle paper, plastic bottles and cans;
- we should use only the water we need;
Some advices: 1)Don’t litter. 2) Clean up after picnics. 3) Go on foot or ride a bike. It’ll help to keep air clean. 4) Feed animals and birds.
Підведення підсумків конференції.
The Earth is our home. Today the contradictions between man and nature are acquiring a dramatic character. Every year world industry pol¬lutes the atmosphere with about 1.000 million tons of dust and other harmful substances. People of many cities suffer from smog. Forests are disappearing and this upsets the oxygen balance. The pollution of the air, of the world's oceans, seas, rivers and lakes, and the destruction of the ozone layer could lead our planet to a global catastrophe. That is why serious measures to protect the environment should be undertaken. As many as 159 countries — members of the United Nations Organization — have set up environmental protection agencies. They have worked out hundreds of projects to protect nature. A global strategy of nature protection has been worked out by a number of international organizations. One of its fundamental provisions is the transfer of industry to low- and non-waste technologies. In our country more attention has been given to the problems of ecology. The State Committee for Environ¬mental Control has been established. The role of Ukraine in the solution of ecological problems has greatly increased.
