Yes, they are clones. So, what is the topic of our lesson?

Р1 –

Р2 – I like … best of all.

P3 – Yes, I do.

P4 – Yes, I like taking pictures very much.

P5 – It seems to me they aren’t. They are simply copies of each other.

P6 – It’s difficult to say exactly, but I suppose they could be clones.

P7 – I guess we’ll speak about clones and cloning.

Teacher: So, our task today is to answer all these questions and to form an opinion whether human cloning is acceptable and whether human cloning should be allowed.

P8 - What is cloning?

P9 - What has already been cloned?

Teacher: But first of all I’d like you to brush your vocabulary. The topic is difficult, there are a lot of terms and we must know them.

What does the word “clone” mean?

What language does it come from?

Let’s look up the on-line dictionary.

Clone (cell biology), a group of identical cells naturally derived from a common parent cell

A clone is a group of identical cells that share a common ancestry, meaning they are derived from the same cell.

http://en.wikipedia.org/wiki/Clone

The term clone is derived from the Ancient Greek word κλών (klōn, “twig”), referring to the process whereby a new plant can be created from a twig.

Read and translate the definition of these terms.

Teacher: Now let’s learn some new words. Let`s move a little bit. Stand up and come here. Choose a card. These are parts of 4 definitions. Some of you have the beginnings, others – the endings. Read your card and make 4 pairs.

Now connect the parts on the blackboard, read the definitions and check yourself. Thanks. Now take your seats.

1. DNA (Deoxyribonucleic acid) -

is a nucleic acid containing the genetic instructions used in the development and functioning of all known living organisms

2. An embryo -

a multicellular diploid eukaryote in its earliest stage of development, from the time of first cell division until birth

3. Embryonic stem cells (ES cells) -

are cells derived from the inner cell mass of an early-stage embryo.

4. Transplantation -

is the moving of an organ from one body to another or from a donor site on the patient's own body, for the purpose of replacing the recipient's damaged or absent organ.

Teacher: Look at the blackboard. These are new words. Remember them. Repeat after me.

DNA - ДНК

ES cell – эмбриональная клетка

Embryo- эмбрион

public opinion pоll – опрос общественного мнения

to starve- умирать с голода

transplantation- трансплантация, пересадка органов

P – читают и переводят

На доске - список слов

Teacher: Let’s do the quiz and find out how much you know about cloning.

Is it true that:

1. cloning is a human invention?

2. identical twins are actually clones?

3. clones have identical DNA?

4.cloned animals live longer than

normal animals?

Teacher: You are right. Cloned animals age faster than normal animals.

Next question. Is it true that:

1. The embryos of mice were first cloned in Russia? (Yes, in 1986)

2. A sheep was the first mammal cloned from adult cell?

3. Dolly, the sheep, was the first cloned in England? (… in Scotland)

Who knows?

P1 – Yes? It is.

P2 - Yes, identical twins, triplets, quads etc are in fact clones.

P3 – Yes, they have identical DNA that’s why they are copies of each other.

P4 – It seems to me that cloned animals can’t live longer than normal animals.

P5 – Unfortunately? I don’t know.

P6 -

P7 – I’m afraid, I can’t answer this question

P8 – I know some interesting facts about the history of cloning.

Слайд 6-7

Teacher: The problem of cloning is very controversial. To my mind we should discuss the ethical, moral, legal, and biological issues of the cloning of human beings. The next point of our discussion is

learning the people’s opinion about cloning in general and human beings in particular.

Listen to the people’s opinions about cloning and say who of them are FOR and who are AGAINST cloning.

(После первого прослушивания учащиеся определяют кто – «за», а кто – «против»

Слайд 8

Teacher: Now I’d like you to vote. Are you FOR or AGAINST cloning? There are two cards on your desks: red card is FOR cloning, green card is AGAINST. Make your choice, please.

Thanks this is your personal opinion now.

Teacher: Work in groups. Give your reasons and arguments. Why have you voted in such way?

What benefits and negative aspects can cloning have?

Учащиеся составляют списки.

«против» -

Teacher: What do other people think about cloning? Special public opinion polls are hold to know people’s vision of this question. Look at this diagram, how can you comment it?

434 ordinary people were asked to give their opinion on cloning.

Teacher: It is the result of special public opinion poll in Europe.

P – I can see that more people are FOR cloning. About 40% of people believe that it opens exiting medical possibilities and more than 4 % of people think that it is a technological breakthrough. Over 21% of people are strongly against cloning. They are sure that it is a catastrophe. 27% of people are indifferent. They think that it doesn’t care them.

P – 71 % of European society (scientists, doctors) are FOR cloning, and only 29 % are AGAINST – it is church.

Teacher: Now you’ll go on working in groups. Read the text. The first group should find more reasons against cloning. The 2^nd group should find reasons and arguments for cloning in addition to this list.

Teacher: Well, let’s add more over:

( к списку FOR добавляется).

Many people are in need of organs for transplantation. But it isn’t easy to get such organs as, for example, heart, liver or

kidneys. Cloning can solve this problem.

(8. Cloning can solve this problem of organs for transplantation).

Teacher: Well, now you. Are there any other reasons against cloning in the text?

Teacher: Now we’ll make some additions to this list.

(6. is against principals of individual freedom and identity.

7. Anti-clonists worry about legal status of a human clone).

FOR

G1 We can add that: (читают)

“…technological progress cannot be stopped.” Supporters insist that cloning isn’t necessarily about cloning people, but they hope that one day therapeutic cloning can be used to generate tissues and organ for transplants. Transplants needed for operations can be created in laboratories, not taken from donors. Diseases like cancer, Alzheimer’s or heart diseases will be defeated.

Growing transplants is an ethically better solution than using donors’ organs.

AGAINST

G2 – Firstly, some people “worry that someone may want to create an army for military purposes, or an army of slave workers.

Secondly, they think, that cloning cam make a negative impact on society as clones will face lots of the social challenges: they won’t have parents, they may be treated as second class people.

Teacher: Open your diaries and write homework
