OF THE 19-21 CENTURIES

- Good morning, friends. At the beginning of our lesson I want you to guess what we are going to speak about today.

    ( Переглянути 1,2 та 3 слайди презентації та виконати відповідні завдання на 2-3 слайдах )

So, we’ll speak about inventions and discoveries and their impact on the development of humanity.

4.All people like travelling . Imagine we  are going to the desert island and you can take only 5 things with you. So you have to choose 5 objects . For doing this task everyone has only 2 minutes. Are you ready? OK. And now each group has to do the same ( choose 5 objects) and the speaker of your group must be ready to tell us about your choice  and the reasons. You have 5 minutes.

19 century- Speaker 1         To survive on the island we should have…

( Inventions of the 19-th century- presentation) 

Thank you. - Why these inventions were typical for that period of time?

                    - Why were they useful?

I agree with you.  But as you know, there were bad sides of the development process.  The 21-st century group , you can write about negative sides of the 19-th century inventions for the people. You have some sheets of paper on your desks.

Are you ready? Who wants to read?

6. We continue our trip to the 20-th century. Let’s speak about the inventions  of  that period of time.

(Inventions of the 20-th century - presentation)  

Thank you. Explain us why have you chosen these inventions? Prove your point of view . Is there any dangerous effect of the inventions of the 20-th century? Critics, speak about it!

OK. I see your viewpoint.

7. As you know we live at information technology age. Not all inventions are ecological safety for humanity. A human being   acquires  also a lot of negative sides from this or that invention. I  want you watch a video about  technogenic disasters.

                            (  Watching  a video )-  1. 5 min

It’s incredible!!!

8. The  21-st century group, it’s your turn to speak about inventions.

9. Now each group will  build a pyramid of scientific discovery value . Before doing this task you have to remember what must be the base of it and what  leads  to the top. On your desks you have a pyramid and a list of words to insert. For this kind of work  you  have some  minutes.

                      The pyramid of scientific discoveries value

economic   benefit

urgency

necessity

changing in people’s  life

innovation

ecological safety

Are you ready? Speakers, represent your group’s work, please.

10. OK. And now let’s do it together on the whiteboard.

What is the base of our pyramid?

What is next? Then? Then? What will be on the top?

Well done!! Our pyramid perfectly shows that ecological safety must be the most important feature of any scientific discovery.

11. Well, we had a lot of types of work  during our lesson. But I want you to return to our quotations. Have you changed your attitude to the inventions and discoveries?

Which of quotations can explain the main idea of our lesson?

I have chosen  another quotation but your choice  is also good.

How do you think what will be useful  for people in future?

What will be the most remarkable?

I  don’t know. Maybe. That’s all for today. Thank you very much.

Good bye!
