Lesson-2 and 3

Before you start

Ask your teacher to explain the word 'mnemonic' and use the technique to memorise the names of the planets in our solar system. Can you think of your own mnemonics?

'mnemonic' /nǝ'monik/ is a device like a rhyme or pattern of letters that is used to remember things. In music for example, the way of remembering the notes of each string on a violin (G, D, A, E) is the sentence 'Good dogs always eat'. This technique allows students to remember things that might be otherwise difficult to learn. Before Pluto was declassified as a planet, the sentence 'My very easy method just speeds up naming planets' allowed people to learn the names of the planets in our solar system in order of their distance from the Sun (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto). Now that there are only considered to be eight planets, students should write a new mnemonic.

3   Listen to the words below in context. Try to guess their meanings.

Audioscript

1. It is easy to float on the Dead Sea; you can just lie back on the water without having to swim.
2. The fence is going to fall apart if the storm gets any worse.
3. NASA's space shuttles flew to and from space 135 times over 30 years.
4. My car is like scrap - it's old and useless.
5. Our old car will be taken to the scrapyard because it can't be driven anymore.
6. Orbital debris is dangerous - something could hit a spaceship and cause a lot of damage.

8 Read the notes on Venus and Mercury. Choose one planet, and think about whether or not we could live on it. Would it be easy to live there? Remember that to survive, you must breathe the planet's air and suffer its climate.

Suggested answer

We could not live on Mercury because the temperature is too hot or too cold (depending whereabouts on the planet you are) and there is no water. We could not live on Venus because it is too hot and we couldn't breathe in the atmosphere.
