                I.Organizational moment

   1.Greetings.

Teacher: Today we are going to discuss how to save our country, our planet from ecological disaster. Listen please, carefully. Сегодня мы собираемся обсудить как спасти нашу планету от экологической катастрофы. Послушайте внимательно. ( чути як шумить дощ , шумить лыс , співають птахи – на цьому фоні вчитель задає питання) What sounds can you hear? Які звуки ви чуєте?

Pupils: forest, rain, the birds are singing… ліс, дощь, птахи співають…

Teacher: Yes, you are right; you can hear the sounds of nature, the sounds of our environment.  Так.вірно. ви чуєте звуки  природи . звучання навколишнього середовища.

II.Post lesson topics and goals.

Teacher: But all these sounds may disappear soon. Why?

              Учень : The reason is MAN who kills animals and birds and destroys their habitats. Forests are cut or burn in fire. Polluted air can cause illness and even death. That’s why we must speak about ecological problems today.

           II. The main part of the lesson

1. Intoduction to the topic.

Teacher :The Earth is the only planet in the solar system where there is life. You can see how wonderful our planet is. Seas and oceans, rivers and lakes high snow-capped mountains green forests and filds. Today people pollute the environment. We deсided to meet here to discuss ecological problems at our region., Chornobyl Nuclear Accident, Chornobyl Problems.

Тeacher :Просухайте вірш

Look at the litter on the streets.

Look at the fish which dead in seas,

Look at the pollution in the air,

Look at the way we just don't care

Today birds are still in our forests,

  And fish in the rivers, but look:

  Don`t kill them! Because your children

  Will see them only in picture books.

            Chornobyl Nuclear Accident

The 26th of April is a special day for the people living in Ukraine and regions situated not far from it. On that day in 1986 a horrible ac¬cident occured at the Chornobyl nuclear station. There was a nuclear reactor explosion which had far reaching consequences.

Contamination by various radioactive isotopes, such as caesium - 137, iodine-131, strontium-90, plutonium-239, and plutonium-240, from the Chornobyl nuclear accident have affected the air, land, and water of Ukraine and vast areas beyond it. Recorded but unreported radiation levels in Kyiv a few days after the accident exceeded the maximum allowable levels by a hundredfold.

Press reports claim that significant numbers of deaths by radiation sickness, elevated levels of stillbirth and birth defects and highly el¬evated rates of childhood leukemia have occured in the affected areas. Those claims and other concerns are being researched by a host of sci¬entists and medical professionals from Ukraine and other countries.

Recent detailed field studies indicate that significant areas of ag¬ricultural and forest lands of Ukraine, Belarus, and Russia will re¬main unsafe for human occupancy and food production for upwards of eight thousand years. Nevertheless, thousands of people who were evacuated after the accident have returned to live and farm in these highly contaminated regions. Thus, the Chornobyl region, in fact, has become something of a living laboratory for the study of nuclear con¬tamination.

A number of foreign countries offered specialised medical equip¬ment and drugs for biological elimination of isotopes of different chemical elements from human body. Later on thousands of children were taken to other republics of the former USSR and abroad for cor¬responding medical treatment.

Such accidents like that in Chornobyl must never be repeated again, because the very existence of millions of people may be under a threat. The safe maintenance of nuclear power stations depends on proper work and sufficient technical knowledge of every worker and engineer.

The Ukrainian people are very greateful to all those who helped and continue to help them.

Chornobyl Problems

The Shelter (popularly known as the sarcophagus) is a potential threat nowadays.

The damaged nuclear power unit still contains some 200 tons of radioactive material. There are no effective means or any reliable physical barriers to prevent radiation from leaking into the environ-ment. At present, the Shelter still contains some 95% of nuclear fuel that was present in the power unit when the planet’s most devastating nuclear accident occurred in 1986.

In the western sector, the wall has a deviation of up to 50 cm, and there are cracks in various places. If a quake measuring 4.3 points on the Richter scale occurs, this will cause some of the Shelter’s roofing to cave in. In the southern sector, over the 24.3 meter level, the reactor body, which contains much of the derbis and construction materials, has deviated from the vertical by some 1.5 meters. Experts estimate that there is a 0.24 risk rate that the southern wall will collapse. In a word, the Shelter in Chornobyl cannot be kept under effective control, given the current facilities.

The Shelter was constructed in a record-breaking six months after the nuclear disaster. It was first conceived as a temporary containment structure built over Power Unit 4, which was wrecked by the explo¬sion, to protect the environment from powerful radioactive emissions. No one denied that the project had many shortcomings, so its service life was set at 10—15 years. The shock from the disaster was also too great to take every detail into account.

Eighteen years have passed, with scientists and politicians periodi¬cally calling for closer attention to the Shelter, but it is still there.

In 1995 the EU and the US sent a clear message to Kyiv: Stop the Chornobyl power units. At the time, the corroding Shelter posed a real and apparent threat to the population of Ukraine, Russia, Bela¬rus, and a number of EU countries (this threat is even more apparent these days), so the EU believed (and still does) that repairing the Shel¬ter is a project that cannot be delayed.

In December 2000, three Chornobyl power units were shut down, primarily in view of the need to renovate the Shelter and build a mod¬ern containtment structure to cover the sarcophagus. In other words, the nuclear power plant was shut down in order to save people’s lives.

                              III.Summary

Teacher: So you see we live in a beautiful world and we must think about our future in order to save it.

“If you don’t think about the future, you won’t have it”, said the famous English writer J. Galsworthy.

You work well.Thank you very much. The lesson is over.See you next time. Good-bye,children.
