2 Introduction to the topic of the lesson.

( Slide 1 ) The topic of our lesson is Science and Cloning. Today’s English studying challenge is 1.to prove that your knowledge & interest in science can be linked with your English class; 2.to improve oral communication; 3.to carry out a virtual experiment to understand how animals are cloned using nuclear transfer. I know that every student wants to get a good mark in the lesson & you are not an exception.

That’s why I’d like everyone to take his/her set of Worksheets & look at the Student Self-assessment. Please write your name and then read and circle the statements in the first section (Slide 2). Please do it as fast as possible.

Do you agree with all these pieces of advice? Would you like to add something else?

So you’ve received a strategy what you should do to achieve the aim of our lesson & get a good mark.

Greeting.

The Ss read the Student Self-assessment and circle the statements in the first section.

Step 1

(Slide 3) Could you tell me what subjects you are studying at school?

You have mentioned biology, physics and chemistry. They are all a part of a school subject called … .

(Slide 4) Do you like science lessons?What kind of things do you do in your science classes?

Step 2

(Slide 5) Science Quiz

Take the Worksheet A, please. It’s a short general knowledge Science Quiz. I want you to complete it in groups. As soon as you finish, we’ll check the correct answers. You have 1 minute to do it.Do you think studying science is important? Why or Why not?

Step 3

Look at the Worksheet B. I would like you to answer the question ‘Which of the following scientific discoveries do you think have been the most important for modern life?

Firstly, do the ranking task individually. Number 1 being the most important, number 10 being the least important. Secondly, work as a group to get your answers to compare. Thirdly, decide upon the top 5 most important discoveries as a

The Ss name the school subjects.

The Ss’ answer is “Science”.

The Ss give their answers.

The Ss discuss the questions.

The Ss work individually and then as a group. Finally, each group report their top 5 to the class.

group. And finally, each group report their top 5 to the class. You have 2 minutes to do the task.

Step 4

Just every group have mentioned Cloning.(Slides 7-11) Cloning

Look at the board, please.(Slide 7 ) What is cloning?Could you explain what cloning means?(Cloning is the process of making an individual that is a genetic copy of another.)What is a clone?(A clone is a genetically identical offspring.)

(Slide 8) Cloning isn’t new.

We can find a sort of clones in Russian tales. Let’s take a tsarina the Frog or a tsarina the Swan. And of course Kashchey Immortal who wanted to be alive eternally.

(Slide 9) Nature’s been doing cloning for billions of years with plants.Things like potatoes and grass send out shoots which can grow into a whole new plant.

(Slide 10) If you grow a plant from a cutting, it’s a type of cloning.

(Slide 11) You might not believe it, but there are human clones among us right now. They weren’t made in a lab, though they’re identical twins, created naturally.

The Ss give their answers.

The Ss follow the presentation.

Identifying and interactive skills

Demonstrating and investigating skills

Identical twins are naturally-occurring сlones of each other even though they are genetically different from their parents.

So why is it in the news?

Yes, I agree. But there are some ethical and moral problems connected with this incredible scientific achievement. We’ll talk about them a little bit later.

The Ss try to guess the correct option:

1. I’m not sure but maybe it is connected with the fact that in the last few decades scientists have been trying to clone animals. And they did it!

2. I completely agree with …. Dolly, ‘the world’s most famous sheep’, was the first mammal to be cloned.

3. Sheep, goats, dogs, cats and mice are animals that have been successfully cloned, too.

4. I would like to add that American and British scientists have announced that they have created a clone of a human embryo. So we are on the threshold of a science breakthrough.

Predictive skills

5Step 5

(Slide 12) What do scientists use to create a clone animal, a clone mammal?

(They use the genes of the first animal so they both have the same DNA.)

Do you think humans should be allowed to be cloned?

The Ss give their answers. (To create a clone they need the genes of the first animal that become the same between the two.)

The Ss discuss the problem:

1. I know that many scientists and doctors, ordinary people are against human cloning. Moreover, parliaments of many countries have banned human cloning, too. I’m also against it because the level of science, to my mind, is not so high yet to be sure about successful results of cloning.

2. I’m also against this idea because we were taught that most attempts to clone mammals fail, or were born alive but died from infections or complications, or were affected with mental illnesses. The same problems would be expected in human cloning.

3. Yes, there are so many unknowns concerning cloning, that the attempt to clone humans at this time is considered dangerous

Step 6

To clone or not to clone? That is the question.Take the Worksheet D, please.Each group has got the discussion cards with two different scenarious about cloning. Please discuss the situations. You have got 2 minutes to do the task. Then I will ask the representative of each group to Express the opinion on the scenarious.

Have you changed your opinion cloning?

5.1. We can make copies

with the characteristics we want.

2. Extinct or endangered species can survive through cloning.

3. Cloning of organs can help their transplant at any time.

4. Cloning can help couples who can’t have children to solve their problem.

Group work. The Ss discuss the scenarious and express their opinions.

The Ss create a clone

(Slide 13) I believe that the next step of our lesson will be interesting and unusual for a language lesson. Why? Because in our vertual lab you will try to create a clone of a baby-mouse. To make a clone you need a computer and an interest in the result of an experiment.

You have to work in pairs, be punctual, follow all the steps given and please try to work as fast as possible. In a real life, the process is time-consuming but it will take less time in our vertual lab. Switch on your laptops. The web address is learn.genetics. utah.edu. Did you find the word Cloning?

The instructions for carrying out the experiment can contain some new words. You can use the Worksheet C to find out the explanation of the words or notions.

So your mission is to create a genetically identical clone of Mimi, a brown female mouse.
