Проблемы экологии

Организационный момент.(2-3 min)

Good morning students, I’m glad to see you today. My name is…..and today I’m your teacher. Let’s start our lesson. Now look at the screen. I’ll show you a short video.

And now guess - what is the theme of our lesson… ( «Environmental problems».)

Yes. You are right. The theme is «Environmental problems» and the aim of our lesson…( to learn about ecological problems and solutions. )We will speak about our planet, ecological problems and solutions. Ecology is a science about nature and about relations of man with it. The word “ecology” came from the Greek which means “home”. This idea of “home” includes the whole planet of ours. Today you are the members of our EcoClub and we are focusing on environmental problems. Before we start our lesson, I suggest you do phonetic exercise.

Phonetic exercise.

Teacher: Look at the screen and repeat after me a tongue twister.

Pupils: Whether the weather be fine

Or whether the weather be not.

Whether the weather be cold

Or whether the weather be hot.

We’ll weather the weather

Whatever the weather

Whether we like it or not.

Now, I’d like to ask you some questions………..

Task 3. Imagine that you are doing a project "Saving the Environment" together with your friends. You have found some illustrations and want to share the news. In 2 minutes be ready to tell about the photos:

-give a brief description of the photos, justifying the choice of the photos for the project;

-say in what way the pictures are different, justifying the choice of the photos for the project;

- mention the advantages and disadvantages (1–2) of the two ways to help save the environment;

-express your opinion on the subject of the project – weather you like to do recycling to help save the environment and why.

Photo 1. Photo 2.

Task 3 . Now let’s watch the  video about plastic pollution. (Здание в группах)

Put the events in the mentioned order.

1. Bottle one ends up in a landfill. As plastics sit there amongst layers of other junk, rainwater flows through the waste and absorbs the water-soluble compounds it contains.

2. Bottles are filled with liquid, wrapped, shipped, bought, opened, consumed and discarded.

3. Bottle two, after months lost at sea, is slowly drawn into a place known as the Great Pacific Garbage Patch. Here some animals get entangled in the mess. They mistake the coloured plastic bits for food.

4. Some of these compounds are highly toxic. Together they create leachate, which can move into groundwater, soil and streams poisoning ecosystems and harming wildlife.

5. Most plastics don’t biodegrade which means they are destined to break down into smaller pieces rotating in the sea eternally.

6. Bottle three is brought into a plant where it is squeezed flat and compressed into a block. The blocks are shredded into tiny pieces which are washed and melted so they become raw materials that can be used again.

7. Plastic makes animals feel full when they are not so they starve to death.

8. Bottle three is now ready to be reborn as something completely new.

Well, now (Quiet music)please sit comfortably. Close your eyes.Breathe in. Breathe out.

Let’s pretend it’s summer. You are lying on a sandy beach. The weather is fine. The light wind is blowing from the sea. The birds are singing. You have no troubles. No serious problems. You are quiet. Your brain relaxes. There is calm in your body. Nothing diverts your attention. you are relaxing. (Pause)

Your troubles float away.

You love your relatives, your school, your friends. They love you too. Learn to appreciate every good thing. The Earth is full of wonders. You can do anything. You are sure of yourself, that you have much energy. You are in good spirits.

Open your eyes. How do you feel? You have a lot of energy. You are active and strong. You can do any work easily. Your body is light.

Ok, are you ready to continue?

Task 4. Read and translate. (Учащиеся читают и переводят тексты в группах)

People have to think about all these ecological problems if they want to survive.

Water pollution

Most big cities pour their waste into seas and rivers and pollute the water. We love rain. Rain helps our plants to grow big and strong. But sometimes the rainwater is not as clean as could be. Man-made chemicals get into the air and mix with the rainwater, making acid rain. If the water is polluted, it can make us sick.

Air pollution

People and animals need clean air with plenty of oxygen in it. Oxygen is added to the air by plants. So, you understand how important it is to have a lot of trees, bushes and grass. But we have now destroyed too many trees. There are not enough trees from the air.

Smoke from the chimneys of the factories, gases which are in refrigerators and sprays pollute the air. Some people pollute the air by smoking. Many people use sprays. Too many sprays can pollute the air.

Land pollution

About one kilogram of trash per person is thrown away every day. Some rubbish is very dangerous. It can poison plants and animals. Some rubbish gets burned. When plastic and some other things are burned, gases are given off. Remember that a piece of paper has two sides – use both of them before you throw it away.

Please open your books…..

Task 6.

The future of our planet depends on each of us. Everyone should contribute to improving the ecological situation in their country. What should we do ourselves to save the Earth? The first group tells what we should do to protect the Earth, the second group tells what we shouldn’t do, the third group tells what we can recycle, reuse, reduce. Before we start to do this task, I just wanna ask you : Who knows what does it (RRR) mean?

R3 is sometimes called the waste hierarchy.

The concept behind the first R: Reduce, is that you should limit the number of purchases that you make in the first place. For example, turning off the lights and taking shorter showers,

The concept behind the second R: Reuse, is that you should reuse items as much as possible before replacing them. For example, it generally makes more environmental sense to update your computer rather than get rid of it and buy a new one. However, if you do replace your computer, you should ensure that it, or its components, are reused. Many charitable organizations welcome donations of second-hand computers.

The concept behind the third R: Recycle, is that you should ensure that items or their components are put to some new purpose as much as possible. If your computer is not fit for reuse as is, you can donate it to one of several organizations which will refurbish it or recycle its components.(Students read)

Now let’s start to do the task(на листке будут все фразы, из данных фраз ребята берут те, которые необходимы для выполнения задания)(пишут в тетрадях)
