Architecture

Arabia / The Middle East

Work in pairs: https://www.365tickets.com.au/burj-khalifa-dubai

Tell me about the Burj Khalifa – the facts; what you can see and do, and practical information

Prepare an information sheet for a guest – be careful to read the website carefully.

Chicago

The Willis Tower: Why doesn’t it fall over ?

The Concorde

What do you know about this commercial supersonic plane ?

This video is quite long (10 minutes+) but has lots of engineering terms and everyday expressions.

Fortunately, it also utilises subtitles which seem quite accurate: https://www.youtube.com/watch?v=a_wuykzfFzE

Write down any words you don’t know – watch the video in short stages, then you can watch at home at your leisure.

The Concorde stopped: why ? What reasons can you suggest ?

Science: Entropy

Entropy: https://www.youtube.com/watch?v=YM-uykVfq_E

The video contains some good expressions.

Famous Scientists

If I say ‘Tesla’, what do you think of ?

Project:

Make a presentation about your favourite scientist or science writer.

Feel free to use slides, pictures, diagrams.

Shinkansen

Bullet Train – top ten facts: https://www.youtube.com/watch?v=b4CD1vErEQQ

This is as much as listening exercise, as an engineering one. How much can you understand ?Which presenter is easier to understand, the young lady or the man from USA ?

Engineering terms

Match the term to the definition:

friction: the product of a body’s mass and its velocity

compression: not of natural origin; prepared or made artificially

momentum: the resistance when a body is moved in contact with another

synthetic: an increase in the density of something

What is ‘friction’ ?

Friction: https://www.youtube.com/watch?v=x_24FBNa788&index=4&list=PL3qtH4RtP-D1xazLKdUeN7QExjbeuCH1n

Listen out for ‘thus’ / exert a force / kinetic (UK pronunciation) / 

Rephrase (put it in your own words):

• what is friction ? 
• How is it caused ? 
• What types of friction are there ? 
• What are the three types of dynamic friction
