Приветствие

Teacher: (В руках яблоко) Use your imagination. The apple represents the Earth. (Разрезает яблоко на 4 части) Three-quarters of the Earth’s surface is water and only one-quarter is land.

(Разрезает кусок, представляющий сушу, пополам) Only one-half the land, or 0.125 the total Earth’s surface is habitable. The rest of the land is the deserts, mountains, frozen ice caps, and other places where people cannot live. (Кусок яблока, который представляет обитаемую землю, разрезает на 4 части) Only 0.25 of the Earth’s habitable land or one-thirty-second is where all the Earth’s food comes from. What would happen if this part of the world were damaged or destroyed? (Съедает этот кусок)

(Берёт маленькую часть от ломтика, который представляет воду – мировой океан) Less that one percent of Earth’s water is fresh and drinkable, and most of this water is tied up in the atmosphere (clouds) and underground.

There are a lot of ecological problems on these small parts of our planet: land and water.

Today I’d like you tell me what you can do to protect our planet. (Вопрос на доске) and make a poster.

At our previous lessons we spoke about ecological problems. Let’s review what they are.

And now let’s consult the diagram on the screen and compare our answers and see if we have missed anything important.

Pupil: We have missed …

Teacher: Do you think these two points are equally important to those we have enumerated?

Pupil 1: Yes! Because noise pollution negatively affects our health and well being. The problems related to noise include: hearing loss, stress, destruction, lost productivity, and a general lowering of the quality of life.

Pupil 2: Deforestation. To on the safe side, deforestation alters the amount of water in the soil, and the groundwater and moisture in the atmosphere.

Well done, thank you very much. I appreciate your answers. Let’s go on.

1. The greenhouse effect. What is it?
2. What can you tell about acid rains?
3. Air pollution. Why does it happen?
4. Water pollution. Why are our rivers and lakes polluted?
5. Disappearing animals. Why does it happen?

Teacher: Thank you for your answers. So, the main causes of ecological problems are (запись на доске): factories wastes, cars bad breath, trash and people. Do you agree with me?

6. Can you do something with factories wastes (cars bad breath)?
7. What can you do with trash?

Pupil 1: We can recycle it.

Teacher: What do you think about recycling in our country?

Pupil 1: Recycling is really badly organized. We can recycle paper, glass, metal and aluminum cans.

Teacher: I know, you have read some information about recycling aluminium cans. (Дополнительный материал, подготовленный учащимися)

Teacher: What to do?

(Ученик предлагает решение проблемы, размещает его на плакате)

Pupil 2: But we produce much more rubbish than we recycle. About 1/3 of trash comes from packaging.

Teacher: It’s true. In Britain, for example, each family throws out one tonne of rubbish each year. And recycle only 2 % of it.

How do you think what packaging is less dangerous?

Pupil 3: Paper. But it takes a whole tree to make about 500 paper grocery bags.

Teacher: What to do? 

(Ученик предлагает решение проблемы, размещает его на плакате)

Teacher: People throw out dangerous things with toxic chemicals.

Pupil 4: Toxic chemicals in batteries can be released into the environment, especially if they are burned.

Teacher: What to do? 

(Ученик предлагает решение проблемы, размещает его на плакате)

Pupil 5: Litter is not only ugly, but it can be harmful to wildlife. Small animals can get hurt on sharp cans or broken bottles.

Teacher: What to do? 

(Ученик предлагает решение проблемы, размещает его на плакате)

Teacher: Must we save water?

Pupil 6: (Ученик предлагает решение проблемы, размещает его на плакате)

Teacher: Must we save electricity?

Pupil 7: (Ученик предлагает решение проблемы, размещает его на плакате)

Teacher: What can we do to protect animals, birds, plats?

Pupil 8: (Ученик предлагает решение проблемы, размещает его на плакате)

Teacher: We have discussed our issue, found some solutions. Our poster is made. Thank you for your work. Let’s see the clip and sing “The Earth Song” by Michael Jackson.
