Открытый урок по теме «Экология. Сможем ли мы спасти планету?»

8 класс

Учитель: Зверева Светлана Петровна,

МБОУ «СОШ с УИМ № 15» г. Магадан



Тема: Ecology. Can our Planet be Saved?

Цели:

  1. Довести до автоматизма речевые навыки до уровня связанного высказывания;

  2. Убедить учащихся в важности решения экологических проблем;

  3. Развивать мышление учащихся, навыки самостоятельной и творческой работы.

Оборудование: постеры, призывающие беречь природу, нарисованные младшими школьниками; раздаточный материал Ecological Glossary, экран, мультимедийный проектор.

T: April, 22 is a special day around the world. On that day people of the Earth celebrate Earth Day. Today at our lesson we’ll discuss a very important problem, may be the most important problem for our Planet and the people living on it.

If you go camping in Canadian national park, you’ll be told (на экране появляется надпись):

Walk lightly on the Earth. See but don’t be seen. Hear, but don’t be heard. What you carry in, carry out. Take only memories, leave only footprints.

T: Don’t you think that these words can be the motto of our lesson today? Many years ago people didn’t have the slightest idea of the term ecology, but nowadays reading newspapers, listening to the radio or watching TV we meet this word regularly, so what is ecology?

P: Ecology is the study of plants and animals in relation to their environment.

T: Yes, but while telling us about ecological problems our ecologists use many ecological notions. Let’s have a look at some of these notions. (на партах учащихся Ecological Glossary)

Let’s read and translate them.

Glossary

Acid rain – when harmful gases from cars and power plants are released into the air and fall back to the Earth with rain or snow.

Atmosphere – all the gases around the Earth

Carbon dioxide – a gas in the atmosphere. The gas that we breathe out.

CFCs – man-made chemicals which destroy the ozone layer

Ecology – the study of organisms and their environment.

Ecosystem - a community of plants and animals living together.

Global warming – an increase in the Earth’s temperature, caused by a build-up of carbon dioxide in the atmosphere.

Greenhouse effect – the Earth is becoming warmer because there is too much carbon dioxide (and several other gases) in the atmosphere. This is called the ‘greenhouse effect’

Ozone (O ) – a type of oxygen

Ozone layer – this is in the atmosphere, between 10km and 60km above the Earth. The ozone stops a lot of the ultraviolet radiation from the sun.

Recycle – to use over and over again. Renewable resource.

Solar energy – energy that comes from the sun.

Smog - brown air pollution that comes from cars and factories; it makes the air unsafe for people, animals and plants to breathe.

Toxic - another word for poisonous.

Ultraviolet radiation – part of sunlight.




T: The protection of nature has become one of the most burning problems. The nature provides people with mineral resources, forests and clean water, but the development of industry has had a bad influence on the nature of the whole world. Our health depends on our environment and we know that the range of ecological problems is wide nowadays. Let’s name them.

P1: Air pollution

P2: Water pollution

P3: Land pollution

P4: Disappearing Animals

P5: The Greenhouse effect

P6: The Ozone holes



T: For today lesson you’ve created some projects to illustrate some of these problems. It’s time to watch them and listen to your comments.

Представление презентаций.

1. The Greenhouse effect

2. Water pollution

3. The Ozone holes

T: Well done! And now some information to think it over. Read and translate some facts about climate. (информация на экране)

Some facts about climate



  • Between 1980 and 1990 the temperature of the North Atlantic rose by 1 C.

  • Alaska had the coldest winter ever in 1988.

  • In the 1980s there were terrible floods in Bangladesh and India.

  • Africa had droughts and famines during the 1980s. Deserts became larger.

  • Britain and France had hurricanes in 1987 and 1990. Hurricanes are very rare here. The strong winds destroyed millions of trees.

  • In 1990 the American Government decided to plant three billion trees – in one year!

T: And now let’s do some more exercises. Match the words in column A with the words in column B:



Column A Column B

A drought happens when there aren’t enough trees

A famine happens when there isn’t enough rain

A flood happens when there is too much carbon dioxide

Trees fall down when there are too many CFCs in the air

The ozone layer become thinner when there is too much rain

The world produces less oxygen when the wind is too strong

The atmosphere becomes warmer when there isn’t much food

There is more skin cancer when there is too much ultraviolet radiation


T: So, what must we do to improve the situation? Of course, there are some solutions of these problems. What can you offer to solve ecological problems? (работа в парах)


T: Today we have spoken about some global problems. At the end of our lesson let’s look at our planet once again. It’s so beautiful!

Earthbig.jpg


P: Yes, our Earth is so beautiful. Nature gives people its riches to live and enjoy. We cannot live without fresh air, clean water, sunshine and a lot of things, which must take care of it. We must keep our rivers and lakes, forests and towns clean. We must plant flowers, feed birds and animals in winter. Then we’ll be happy to live on the most beautiful planet in the Universe.

Тема: Ecology. Can our Planet be Saved? Предлагаемая разработка позволяет довести до автоматизма речевые навыки до уровня связанного высказывания; убедить учащихся в важности решения экологических проблем; развивать мышление учащихся, навыки самостоятельной и творческой работы. Презентация была опробирована на реально проведенном уроке, учащиеся были в восторге.Но самое главное была достигнута поставленная цель. однако при использовании данной презентации не советую использовать ее такой какой есть,потому что,уважаемые коллеги, у каждого у нас есть своя методическая система,и разработки подобног рода необходимо адаптировать под каждую из них.
