1. ENVIRONMENTAL ISSUES___________________________________________________________________________________________________________________
1. Brainstorming the environment: A mindmap. Here.
1. Watch the following video: "Global Warming Cartoon" by Al Gore:
http://www.youtube.com/watch?v=QLW2T3QgJc02. Work with a partner: watch it again and describe in your own words how Al Gore tries to explain global warming. Do you find it funny, absurd, wrong, right?
3. Comprehension activity: Before listening, match the following words to their definitions.
Word Definition1. Radiation a) A large hole in the ground where waste is buried.
2. Carbon dioxide b) The slow increase of the Earth’s temperature
3. Landfill c) The broken pieces left when something large has been destroyed.
4. Fossil fuels d) A gas without colour or smell, produced when you breathe out.
5. Debris e) Fuels produced from decayed animal or plant material.
6. Global warming f) A form of energy produced during a nuclear reaction.
Now listen to the following British Council audio: http://www.learnenglish.org.uk/prof_mp3/The_Greenhouse_Effect.mp3Audio script here.
4. Places and people: threats and dangers.
[Teacher notes: - Explain the activity: Students will choose a location (e.g., in forests), and they must make as many statements as they can about it while using passive sentences.
- Model the task by giving this example: In forests. Ask students to think of things that are being done or have been done in forests anywhere in the world. Remind them to use the passive. Write their suggestions on the board:
In forests
Trees are being cut down.
Not enough new trees have been planted.
Many animals' homes have been destroyed.
- Now write the following locations on the board:
in large cities on farms | | in mountain resorts in coastal towns |
- Students work in pairs or groups. Tell them to choose two locations to discuss and to write down their sentences for each one. Set a time limit of seven minutes. Go around and give help as needed.
- Call on students to read aloud some of the sentences they wrote. Which pair or group wrote the most (and the best) sentences?]
5. Discussion. Agreeing/disagreeing: Giving Opinions & Agreeing /
INTRODUCING OPINION
| AGREEING
| DISAGREEING
|
In my opinion... I would say... Personally, I feel... The way I see it is...
| Absolutely! Exactly! I couldn't agree more I agree with you completely I would agree with your point of view That's how I see it too. I couldn't have said it better myself.
| I don't quite agree I don't see it that way That's not how I see it I would disagree with that I couldn't disagree with you more I see your point, but... I understand how you might see it that way, but...
|
5.1. General practice: Make statements in which you give your opinion on the following topics. Your partner(s) will agree or disagree with you. Follow up with a reason
for your agreement or disagreement. Then switch roles.
E.g. You say: "In my opinion, George W. Bush is a great president..." Your partner says: "Sorry, but I couldn't disagree more. In my opinion..."

Listening comprehension:
1. While you listen, decide whether the following sentences are true or false.a. Recently great advances have been made in motor technology.
b. Engineers are constantly looking for new ways to use existing models.
c. Engineers have more freedom for experimentation than in Faraday’s times.
d. The newest motors lose more heat than the traditional motors.
e. The newest motors are more compact than they used to be.
f. A new motor developed by Omron may replace motors currently used in
hydraulic systems.
2. Fill in the gaps with the appropriate word.
Student A: You have the words Student B needs and Student B has the words you need to fill in the gaps. Student B will mimic or draw the 4 words you need. You are not allowed to speak. Likewise, you will have to mimic/draw those words with the numbers in brackets.
So – back to motors. What’s happening at the moment is very exciting. A new kind of motor has been
developed which uses internal permanent ___________ embedded within the rotor (1). These magnets (2) improve the
motors’ flux density and torque density. What does this mean? Well, for a start the motors use less energy –
considerable less than traditional motors. This is because there is less __________ loss. A side effect of this is that the
machines using the new motors have increased precision. Size (3) and __________ are two further aspects. . The new
motors are a lot smaller and speed control is more efficient. This is especially important when we use the
motors in ___________ or cranes (4) for example.

1. Read the following excerpt (full text here):
Researchers at MIT have shown that it's possible to wirelessly power a 60-watt lightbulb sitting about two meters away from a power source. Using a remarkably simple setup--basically consisting of two metal coils--they have demonstrated, for the first time, that it is feasible to efficiently send that much power over such a distance. The experiment paves the way for wirelessly charging batteries in laptops, mobile phones, and music players, as well as cutting the electric cords on household appliances, says Marin Soljačić, professor of physics at MIT, who led the team with physics professor John Joannopoulos.
Would you reckon this as a useful development for society? Why?

6.4. Group of 3 students: decide who's going to play the role of venture capitalist. Once you have decided who has the money, you and your classmate will have to choose one of the future technological developments you polled before. You are interested in setting up a business to develop such idea but you need the money. You will have to explain in 10 minutes or less why the business angel should invest in your option: be brief, clear and stick to the point.
[Teacher notes: Divide up the class in groups of 3. In each group a student will play the business angel role. Explain what a venture capitalist is, if necessary, and the subtle difference between venture capitalists and business angels. The other two students, student A and student B, will have to choose a future technological development: they want to create a start-up company to develop such idea but they need funding. They will have to convince the business angel that theirs is the best option. Tell them to stick to the point: brevity, clarity and to back up their choice with examples, the business angel will need to know if your plan is solid.
