I. Оргмомент

(Вхожу. Дети встают.)

-Good morning / afternoon, class. Sit down, please. (Дети садятся.) My name is Andreeva Olga Vladimirovna. I am the teacher of English at Samara Lycee of Information Technologies.

-What can you see in the photo? (Дети: Earth. Planet Earth.)

(на слайде – планета Земля, рядом – Земля в «плохом» состоянии, внизу – фото Земли в руках человека)

-How are these photos connected with the topic of our lesson today? (Дети: environment, pollution, saving the Earth, protecting the Earth)

(слайд с темой урока – Protecting the environment)

You’ve been discussing this topic for many years in different lessons.

Can you answer the following questions now: 1) What do you know about the ecological situation in the world? What are the most polluted regions? 2) What are the most urgent ecological issues nowadays? 3) What, in your opinion, needs to be done in order to improve the situation?

III. Активизация знаний

While we’ve been discussing these questions, we’ve mentioned some words related to the topic. Now let’s look at them, and other words as well, once again.

(слайд со словами)

Look at these words and divide them into groups. How many groups can we make? (Учащиеся: 2 groups: problems and solutions. Делят слова на группы.)

(слайд с ответами)

Very well. Now, who can give me the definition the word ‘pollution’ (damage caused to water, air, etc.  by harmful substances or waste)? ‘global warming’ (an increase in the temperature of the air around the world because of pollution)? ‘recycling’ (the process of putting paper, glass, plastic, etc. through a process so that it can be used again)?

And a few more words: (слайд со словами). Match synonyms. ( a) conserve PRESERVE b) combat FIGHT c) address COPE WITH d) impact AFFECT e) contaminate POLLUTE f) at stake IN DANGER g) destroy DAMAGE h) severe SERIOUS)

Great job! Now can you ask questions using the words from the previous activities and these question words: Who? What? Where? When? Why? (Учащиеся задают вопросы: Who can preserve nature? What destroy natural habitats? What is at stake? Where deforestation takes place? When did the global warming start? Why recycling is so important?)

III. Обобщение знаний

Excellent. But, unfortunately, we can’t discuss all environmental problems today. That is why we are going to talk only about one, but quite important thing.

(Обращаю внимание учащихся на коробку на столе.)

In nature everything is closely connected, although some single phenomena are more important than others in the natural balance of both living and non-living matter.

What substance, in your opinion, is hidden here in the box? It’s the most important one on the Earth. These riddles can help you to guess. (слайд с загадками)

(Ответы учащихся)

Yes, it’s water,(Достаю стакан воды из коробки.) one of the riddles of our planet that a lot of humans are trying to solve, but no one has succeeded yet. Antoine de Saint-Exupery (слайд с высказыванием) once said: ‘We admire you without knowing what you are!’

Let’s see what YOU know about it.

(слайд со словами и предложениями с пропусками)

Fill in the gaps using the words given.

(Water is the most common substance on the Earth. Water is chemically active. It reacts with many simple and complex substances. Water is a unique solvent for solid, liquid and gaseous substances.)

What is the chemical formula of water? (H2O)

(слайд с картинками)

Who and when introduced this formula? (Joseph Louis Gay-Lussac in 1805)

(слайд) What water properties do you know? As for taste…(tasteless), as for colour…(colourless), as for smell…(odorless).

(слайд) What are the three states of water? (Liquid, solid, gaseous).Give example of liquid state? solid state? gaseous state?

(слайд) Look at the map. What two civilizations considered water as healing one? (Chinese and Indians)

What percentage of the Earth’s surface does it cover? (approx. 71%) (слайд)

And humans consist of about how many per cent water? (70%) (слайд)

So, as we can see, it is vital for all known forms of life.

Please, can you summarise what we’ve just revised about water. (слайд) (Ответ учащегося.)

Thank you. Now work in pairs and write a syncrane. (слайд) (Учащиеся зачитывают свои варианты. Если есть затруднения – работаем вместе.)

But still people don’t consider water as a treasure of our planet. A lot of fresh water (пресная вода) is used for industrial needs, and some countries are suffering from the lack of fresh drinking water. Thus, Germany brings fresh water in the country from Sweden.

(слайд) Look at this diagram. Explain, what you can see on it. (Ответ учащихся.)

Fortunately, people are starting to realize the importance of protecting environment, and water as well. There appear different organizations that try to draw our attention to the ecological problems of the present day even in quite creative way (слайд с постерами).

(слайд с картинами)

Look at these pictures of the past. Describe one of it and think …what can cause water pollution in the painting you’ve chosen. (Ответы учащихся.)

And what can WE do to save water? (Предположения учащихся.) (слайд)
