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.

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

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

4. 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

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

A. 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.

B. 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.

C. 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?
