4. Discuss the questions below in pairs.

1. Can you give example of books or films about cloning? 2. Would you like to be cloned? 3. Why do you think cloning was banned in some countries? 4. What are the advantages and disadvantages of cloning in your opinion?

4. You are going to have the debate about cloning. Work in two groups.

Group A: a) Make a list of reasons for cloning, b) Choose the arguments for cloning from the list the teacher gives to you. Add them to your list.

Group B: a) Make a list of reasons against cloning, b) Choose the arguments for cloning from the list the teacher gives to you. Add them to your list.

6. Have the class debate. Use the words and phrases below and your own ideas.

I see your point, but I think ...

Yes, I understand, but my opinion is that...

That's all very interesting, but the problem is that...

I'm afraid I can't quite agree with your point...

I'm sorry, but I don't think that's quite correct...

Sorry, I just have to disagree with your point...

Well, I think that...

Here's the main point I want to raise ...

Just to be clear, here is what I mean ...

So finally, we ...

LESSON 5. NANOZOOM

Communicative area: simplifying, explaining

Active vocabulary: atom, molecule, bacteria, scale, structure

1. a) Match the words below with the pictures. What's the smallest possible particle?

2. Look at the nanoscale and read about it. How small is one nanometer? How tall are you in nanometers?

Ordinary objects are absolutely huge measured on what scien­tists call the nanoscale.

Atom: -0.1 nanometers.

Atoms in a molecule: -0.15 nanometers apart. Typical bacteria: -200 nanometers long. Human hair: -10,000 nanometers in diameter. One piece of paper: -100,000 nanometers thick. Man 2m tall: ~ 2000 million nanometers tall.

2. Work in pairs. Can you guess what the following words mean?

Nanometer, nanostructure, nanoparticle, nanomaterial, nanotechnology, nanoscale, nanorobot, nanoscience, nano- sized, nanomachine.

2. 0 a) Listen to the interview with Robert Chang, Ph. D., director of the National Centre for Learning and Teaching. Is nano­technology good for you? Why?

© b) Listen again and complete the tasks below.

1. Write definitions for: nanoscience; nanotechnology.

2. Note down at least:

two examples of nanotechnology in nature; 3 areas where nanotechnology is used today; 1 example of future technology

3. Explain:

how scientists work on nanoscale; how nanoparticles can change different materials

2. Look at the pictures below. Match the texts to the pictures.

1. In 1989, IBM researcher Don Eigler used a microscope like this to spell out the word I-B-M by moving individual atoms into position. Other scientists have used similar tech­niques to draw pictures of nanoscopic guitars, books, and all kinds of other things.

2. An award-winning British invention - self-cleaning glass - will fill the NanoHouse's window frames. It works us­ing a 15 nanometer coating that promotes a reaction between the Sun's UV rays and dirt. The broken-down dirt is washed away by rain.

3. Butterfly wings are perfectly structured down to the nanoscale in a way that makes them reflect light in a beautiful and amazing way. Bank notes could one day be made as beauti­ful as butterfly wings. Mr. Kolle and two professors from the university's Cavendish Laboratory made identical copies of the structures using advanced nanotechnology.

   6. Discuss the questions in pairs.

      1. Are you impressed by nanotechnology?

      2. How could nanotechnology make a smart home more ad­vanced?

      3. What do you think the dangers of nanotechnology might be?

      4. Wouldn't it be exciting to be a nanoscientist?

   7. Imagine you are going to give a lecture about nanotechnology to a group of 8 year-old kids. Prepare your speech.

Idea: Describe the world of Nanokids - kids that are smaller than hairs on an ant's leg.

LESSON 6. HOW SMART IS YOUR HOME?

Communicative area: describing functions, describing a house Active vocabulary: security, appliance

1. Discuss the questions below in pairs.

1. What do you think the homes of the future will look like?

2. What will they have inside?

3. In what ways will people's life at home be different?

2. a) Read the advertisement below. What is its aim?

Calls for future family to trial smart home, rent free

The NSW government is calling for volunteers to test a technologically advanced home in Sydney's Newington. The trial is about taking technology out of the lab and testing them in the real world, minister for Energy, John Robertson, said. "We are looking for a family with children because we know that kids will use technology different to their par­ents," he said.

The residents will be able to control devices using an iPod, watch an 'organic' LED television and drive an electric car. The family will have to keep a lively blog and they will need "a good sense of humour and plenty of patience" because things will not always work perfectly, Robertson said. The Smart Home fa­mily featuring a resident writer, would live in a three bedroom home in Newington for 12 months. Interest­ed families can go to www.tqqiderlink.com /energy from today for the selection criteria.

b) What kind of people are they looking for? Why? Would your family take part in a project like this? Why?
