The fourth group: professors of plants world.
The fifth group: professors of outer space
and ecology man.
T. Listen to the poem, I fully agree with the English poet Devis, who said:
What is this life, if full of care.
Weve no time to stand and stare.
No time to see when woods we pass.
Where squirrels hide their nuts in grass
No time to see in broad daylight
Streams full of stars like skies at night
A poor life this, if full of care
We have no time to stand and stare.
T. Really, our life is poor, when we have no time to put aside our work and just go to the forest or to the field, to see their beauty and enjoy the local landscape and what do you think about it.
Your presentations, professors.

WATER IN OUR LIFE
Life is a zoo in a jungle.
Peter De Vries
WATER AND WATER PLANTS
On our planet there is a lot of water; the water is in rivers, in lakes, in ponds, in seas and in oceans. The ocean is a very big sea. The water in the sea is salty, but in the river the water is fresh. In the water live many plants. The water lily floats on the top of the water.
In the water live fish and animals. A fish moves its tail from side to side and swims in the water; its tail is its propeller. Fish are covered with scale. Some fishes eat plants or smaller fish and worms under the water; others eat flies and other insects on the top of the water.
Some fishes are very big; the biggest fish are sharks. A dolphin is as big as a shark, but it is not a fish it is a mammal. Dolphins feed their babies with milk. But the biggest water animal is the whale; some whales weigh several tons. Whales live in the oceans; they are mammals too.
SEA TURTLES IN DANGER
Sea turtles come in different colours, shapes and sizes and are found in many parts of the world, from Mexico and Costa Rica in Central America to Turkey and Greece in the Mediterranean. They have existed for millions of years but their survival is now being threatened.
It has been estimated that severe storms (notably hurricanes and tornadoes) account for about 20 per cent of the huge annual cost of the damage caused by natural disasters. The most common storms, however, are thunderstorms, about 50.000 of which occur every day.
The most destructive waves in the ocean are tsunamis, often wrongly called tidal waves. They are not caused by tides, but by underwater earthquakes, landslides, volcanic eruptions, or by hurricanes. These disturbances cause the sea bed to move very quickly, which shifts a large amount of water and disrupts the sea surface. A train of waves is set in motion and travels away from the source of disturbance.
IMPORTANCE OF WATER
Water is necessary for life. All organisms contain it, some drink it and some live in it. Plants and animals require water that is moderately pure, and they cannot survive, if water contains toxic chemicals or harmful microorganisms. Water pollution kills large quantity of fish, birds, and other animals, in some cases killing everything in an affected area.
WATER AND ITS PROTECTION
We must keep water clean in rivers and lakes, because we need clean water for drinking. Plants and animals die in the water which is polluted. Especially great harm to the river and lakes is done by oil products. That is why the law forbids to drain harmful and waste waters to water reservoirs. It also forbids to cup the forests around the water reservoirs because then they become shallow.
THE MAIN PROBLEM of WATER POLLUTION
The problems associated with water pollution have the capabilities to disrupt life on our planet to a great extent. But global environmental collapse is not inevitable.
Pollution, pollution you can use the latest toothpaste
And then rinse your mouth with industrial waste.
Just go out for a breath of air
And youll be ready for a Medicare.
The city streets are quite a thrill
If the hoods dont get the monoxide will.
Pollution, pollution wear a gas mask or a veil,
Then you can breathe long as you dont inhale.
Fish gotta swim, birds gotta fly
But they dont last long if they try.
A generation which doesnt think of nature will not have future!
What influence have a water world on the peoples life?
What do you think about water pollution?
2) T: Professors of flora, please
The Plant Life On Our Planet
Life is Just a mirror, and what you see out there, you must first see inside of you.
On our planet plants live from the tundra in the north to the tropical forests at the equator. In the Arctic the climate is very cold, snow never melts in summer; that is why few plants live there.
The tundra lies to the south of the Arctic; there are no big trees but there grow grass and moss. Forests lie to the south of the tundra; in the forest grow such trees as oak, birch, maple and others.
Forests are “the lungs” of our planet. That is why they are protected by law. The worst enemy of a forest is fire. It is necessary to be careful in the forest especially when the weather is dry and windy.
A big tree
Is like a giant
With torn-out roots
Instead of feet.
Its like a ship
Sailing far out to sea,
or a house with many rooms.
It has places to hide
and swing on
and climb along.
A big tree
is a good place to play.
But you can never make it stand up again.
Among the meadow grasses,
Bluebells and daisies gleam,
And forget-me-nots often hide
Beside the silver stream.
Bright tulips and sweet roses
Make many gardens gay
Oh, who could count the flowers
Upon a summers day?
Saving the environment, you save yourself!
What do you think the plants are very necessary in our life?
3) T: Professors of fauna, please
THE ANIMALS WORLD
Civilization begins with order, grows with liberty, and dies with chaos.
Will Durant (1885-1981)
Every year more animals disappear never to be seen again.
Nature is carefully balanced and if this balance is disturbed everyday, thousands of species of animals draw closer to extinction.
THE ANIMAL LIFE ON OUR PLANET
MANY ANIMALS AND INSECTS LIVE IN THE STEPPE, IN THE PRAIRIE AND IN THE SAVANNAH. IN THE SAVANNAH LIVE ZEBRAS, LIONS AND OTHER BIG ANIMALS.
Tigers are of cat family. They are the largest cats. Tigers are orange and white with black stripes. They have a big body and a long tail. Their teeth are big and sharp. Tigers are very strong and dangerous. They eat small animals and fish. They live in Asia and in Africa. Tigers can run very fast and swim.
Monkeys live in the forest of the warm countries. Monkeys climb up the trees with their hands and legs. Hey climb down the trees very seldom, because he trees give them all necessary food young leaves, juicy shoots and fruit. They find drinking water in the hollows of the leaves where it gets after the rain. On the ground monkeys move with the help of arms and legs.
The problem is acid rain. Acid is a kind of air pollution. It is caused by factories the burn coal or oil, or gas. These factories send smoke high into the air. The wind often carries he smoke far from the factories.
Every ten minutes one kind of animal, insect dies our forever. If nothing is done about it, one million kind species that are alive today may soon become extinct.
Stop wining the habitat of insects animals and reptiles! Think about rare species.
What are the methods do you know to save animals life.
4) T: Professors of landscape, please
A country without trees is almost as hopeless.
Trees in Danger
Man and the Landscape
Danger of forests
Look after your planet, its the only one we have. Our world is in danger! Think!
What is the main problem of landscape?
5) T: Professors of outer space and ecology man
Ecology of Man.
Between 7 and 20 million years ago, primitive apelike animals were widely distributed on the African and on the Eurasian continents.
A sound body is in sound mind.
Diversity of People and Globalisation
The main urban problems.
Global warming and global changed
The bird of paradise alights only upon the hand does not grasp.
The nature of the sky
If you look at the sky you can see clouds. Sometimes clouds are white but sometimes they are dark and grey. Clouds are made of millions of water-drops. In winter clouds are made of snow-flakes and ice-bits. But when the weather is fine, the sky looks blue, because the sunshine consists of many colors. When the sunlight shines through the atmosphere we can see only one color-blue. But sometimes, especially during the rain, We can see red, grey and others colors.
The protection of nature has become one
of the most actual problems of the 20th century.
The development of industry had a bad influence on the nature of whole world. It is very dangerous for people and animals. The intensive development of industry results in air pollution. Metallurgical plants in a number of cities account for most of their total air pollution. So I calls on protection of the natural wealth and on using it in a more careful and economical manner for the benefit of the present and future
The accident at the Chernobyl
All the people live on a planet. Our planet is called the Earth.
The Earth is in Space; it moves around the Sun. the Sun is a Star; it gives us light and warmth. In Space there are many other Stars, but they are far from our planet. We can see stars only at Night when the sky is dark. The Sun and other stars make a galaxy.
Our galaxy is called Milky Way. At night in the sky you can see the Moon too
The hole in the Ozone layer
Discovery of the hole in the ozone layer showed that human activity has a major impact on the Earth. The damage of ozone in the stratosphere high above the planets
surface has been brought about as the result of the widespread use of chemical, which
under normal conditions are chemically inert and harmless.
When you look at the sky you can see the Sun. The Sun is a great big ball of hot gases. The sunshine passes through Space and air and comes to our planet. Then one side of the Earth which faces the Sun has day. The other side has night. Our planet moves around the Sun in twelve months. The Sun is very beautiful and amazing star and there is no life without Sun.
At night we can see the Moon at the sky. The Moon is a big shining ball. We can see only that side of the Moon which faces the Sun. The moon is dark but it reflects the sunlight and shines brightly at night. Through a telescope we can see mountains and plains on it. But there are no people or trees there, because there is no air or water on the Moon. And I know that Moon is very romantic star, because many Sweethearts sitting under the Moon.
Stars are great big suns. there are many millions of stars in the sky, but we can see them only a telescope, because there are far away. In day-time we cannot see the stars because of the sunshine, but at night, when its dark the stars appear in the sky. Some stars make groups. One group of stars has the name is the Great Bear. The brightest star in the sky is Sirius.
What do you think about the importance of sport in our life? What is the main problem of ecology of man.
What do you think outer space is another world?
