( Warming up ) (слайд №1)

-

As you know it’s difficult to overestimate the role of

science and technology in our life. They accelerate

the development of civilization and help us in our co-

operation with nature. Scientists investigate the laws

of the universe, discover the secrets of nature, and

apply their knowledge in practice improving the life

of people.

-

But

every

medal

has

its

reverse.

And

the

rapid

scientific progress has aroused a number of problems.

-

These are ecological problems.

T: First, I’d like to know what ecological problems do

you know about? This scheme will help you.

( слайд № 2 Ecological problems )

PP:

Endangered

animals,

New

local

wars,

Pollution,

Dangerous technologies, Dangerous diseases, Star wars,

People

and

their

interrelations,

Lack

of

recycling,

Breaking human rights, Crimes, Drugs.

T: But what is the most important problem? And what do

you think about it?

( слайд № 3 The most important problem is… )

P1: I think the most important problem is endangered

animals

because

many

species

of

animals

and

birds

disappear and it’s the man’s fault who has polluted their

natural homes.

P2: I believe the most important ecological problem is

pollution because it is very dangerous for people, wildlife

and the environment.

P3: It seems to me that the most ecological problem is

dangerous diseases. Let’s take for example AIDS. There

several types of AIDS. No one has been cured up to the

present moment.

P4: To my mind the most ecological problem is drugs.

More people are abusing drugs today than in any other

time in history and many of them are youth.

T: And I’d like to add that people have always polluted

their countries. Some years ago it was not a serious

problem. But now it has become more serious.

What are the reasons for it?

1. Защита проектов ( контроль домашнего задания )

T: At home you were to think them over and now present

your ideas to us. The rest of you are to listen carefully.

( слайд № 4 Deforestation and endangered animals )

P1: We are going to tell you about Deforestation and

endangered animals.

( слайд № 5 Destruction of the tropical forests )

-

It’s generally agreed that the Destruction of the

tropical forest has a major impact on the world

climate. The tropical rain forest is a natural recycler,

provider and protector for our planet.

-

P2: It recycles carbon, nitrogen and oxygen, helps to

determine temperature, rainfall and other climatic

conditions. It supports the most diverse ecosystem in

the world.

( слайд № 6 The forests are in danger )

P 3: I fully agree with you. The forests are in danger. The

world has over 9 million sq. km. of forests. But they are

disappearing fast not only of fires. Every day we use

paper and cardboard made from wood. We use different

kinds of wood to make furniture and other things. Every

year huge forests are cut down for different uses.

( слайд №7 Endangered animals )

P4: You can’t deny the fact that there are a lot of

wonderful animals on our planet. In the oceans there are

whales, sharks, polar bears, penguins. In tropical forests

there are snakes, jaguars, in rivers you can see different

kinds of fish and crocodiles. But many of these species

are disappearing nowadays.

T: Well done. Thank you very much. Let me mark your

answers. Don’t forget to write down them in your report

cards.

T: Now the next group, it’s your turn.

( слайд № 8 Overpopulation)

P1: We are going to tell you about overpopulation. In my

opinion the world’s population is an important issue. For

hundreds of thousands of years, the human population

grew at a low but steadily increasing rate. Then, in less

than

last

200

years,

the

world

population

went

from

several

hundreds

of

millions

to

more

than

6

billion

people.

(слайд № 9 Overpopulation is destroying …)

P2: I want to add this. Overpopulation is destroying our

environment,

lowering

the

standard

of

l i v i n g .

Overpopulation also causes more violence, environmental

pollution that reflects on land degradation, tropical forest

destruction,

global

warming

and

destruction

of

coral

reefs.

P3: 6 billion member society has to get a huge food

infrastructure, so society start producing genetically made

food. In conclusion I’d like to say that the planet urgently

needs population control.(слайд№11Popul. control)

T: That’s a good job. Let me mark your answers.

(учитель оценивает каждого ученика с помощью

-

Go back to your places.

T: And now it’s the turn of the third group. Will you come

out to the front and present your project.

(слайд № 12 Chernobyl Catastrophe)

P1: In April 1986 a catastrophe broke out 12 kilometers

off the Belarusian border.(демонстрация фильма 30

сек) It was the major breakdown of the power unit at the

Chernobyl nuclear power station.

P2: As the result of the explosion of the failed reactor a

huge amount of radioactive substances was released into

the atmosphere. Later on they left the large fallout “spots”

on

the

ground

surface.(слайд

№13…)

23%

of

the

territory of Belarus, 4,8% of the territory of the Ukraine

and 0,5% of the territory of Russia were contaminated.

P3: After the Chernobyl accident Belarus has become the

zone

of

the

ecological

disaster.

260,000

hectares

of

agricultural

lands

are

forbidden

to

use. Thousands

of

hectares

of

forests

are

contaminated

with

radioactive

elements. The

Chernobyl

catastrophe

has

affected

the

destinies of millions of people.(слайд№14…)

T: Thank you for you presentation. I’ll give you …

(учитель оценивает каждого ученика с помощью

разноцветных жетонов)

And our last presentation is called modern

technologies. You are welcome.

(слайд №15 Modern technologies)

P1: For thousands of years people lived in harmony with

environment. But with the development of civilization

man’s interference in nature began to increase.

(демонстрация фильма Green Peace 50 cek)

P2:

Large

cities

with

thousands

of

smoky

industrial

enterprises appear all over the world. The by-produtcs of

their

activity

pollute

the

air

we

breathe. As

I

know

polluted air can cause illness.

P3: I agree with you. Factories emit tons of harmful

chemicals. These emissions have disastrous consequences

for our planet. They are main reason for the greenhouse

effect and acid rain.

P4: The seas are in danger. They are filled with poison:

industrial and nuclear wastes, chemical fertilizers and

pesticides.

(слайд №16)

Every ten minutes one kind of animal, plant or insect

dies out forever.

Air, water and soil are necessary for existence of all living

things.

T: You’ve done a good job. Thank you very much. Let me

mark your answers.
