What a wonderful world

Module 37

Vocabulary and grammar

Activity 1

To identify opposites [lo 6.6.2]

When Mark Shuttleworth saw the earth from space in April 2002 he described it as looking fragile. It is true that our planet could “break” if we don’t look after it properly. We have to find ways of ensuring that development continues without using all the earth’s natural resources. In August 2002 a very important world summit (meeting) on Sustainable Development was held in South Africa to help all the countries of the world to protect the earth.

Some of the issues that were discussed were the following problems:

  • More than 11 000 species are in danger of becoming extinct;
  • Forests covering about a third of the surface of the earth, have shrunk by about 2,4% since 1991 as a result of mining and timber activities;
  • About 1 100 million people don’t have access to clean drinking water (most of them in Africa and Asia);
  • Half of the world’s rivers are polluted or practically dry; and
  • Oil, gas and other “greenhouse” gases are causing global warming.

Each one of us, in his/her own small way, must fight against pollution and the exploitation of our animals and natural resources. We must show that we respect each other and all of nature.

1. Write five short simple sentences (one verb only in the sentence) and suggest what young people like you can do to help fight pollution.

2. The following words have been taken from the passage above. Give a word meaning the opposite (an antonym) for each:

(a) fragile ………………………………………..

(b) help ………………………………………..

(c) protect ………………………………………..

(d) clean ………………………………………..

(e) small ………………………………………..

3. Look at the following words from the passage, and see how their opposites are formed:

  • properly - im properly
  • continue - dis continue
  • natural - un natural
  • important - un important
  • natural - un natural

Can you see that they have been formed by adding a little bit to the word (at the beginning of the word)? This “little bit” is called a prefix. Do you know any other words that form their opposites in this way? If you do, write them down here:

Write all these words in your personal dictionary and make sure that you know how to use them. Ask your teacher for help if necessary.

Activity 2

To understand and use singular and plural forms of ordinary nouns [lo 6.4.1]

4. Most nouns (naming words) have plural forms. That means that the words indicate that there is more than one of the things that are being named, for example:

one planet - many planets

one country - many countries

one animal - many animals

one river - many rivers

one meeting - many meetings

Activity 3

To understand and use nouns which do not have plurals [lo 6.4.2]

Some words, however, don’t have a plural form at all, for example:

tourism, space, exploitation, respect, pollution (as used in this module)

See if you can find any other nouns that don’t have a plural form.

Activity 4

To use a dictionary [lo 6.6.3]

5. Did you notice the spelling of gases ?

We also write buses (one bus / many buses).

Remember to spell these words correctly at all times!

Write them in your personal dictionary.

And finally, just for fun……………

Do you remember the creation myths we started off with? In most of the creation stories all is well on earth up to a certain point, and then the trouble starts. Someone is usually disobedient or mischievous and causes evil things to happen. (In the Bible we read that Adam and Eve were disobedient and that is when sin came into the world.)

In Greek mythology, there is a woman called Pandora. She was the first woman ever to set foot on earth. Pandora wasn’t as good as she seemed to be. In fact, she was the cause of all the trouble on earth …

Do some research on the story of Pandora. You could make up a wonderful little play on it. How about it?

OR

Dramatise any scene based on the protection of nature, e.g. police trying to capture poachers.

Assessment

Learning outcome 6: language structure and use

The learner will know and be able to use the sounds, words and grammar of the language and interpret texts.

Assessment standard

We know this when the learner:

6.4 understands and uses singular and plural forms of nouns:

6.4.1 ordinary nouns;

  • nouns which do not have plurals;

6.6 develops own vocabulary:

6.6.2 identifies opposites;

6.6.3 uses personal dictionaries.

Questions & Answers

Three charges q_{1}=+3\mu C, q_{2}=+6\mu C and q_{3}=+8\mu C are located at (2,0)m (0,0)m and (0,3) coordinates respectively. Find the magnitude and direction acted upon q_{2} by the two other charges.Draw the correct graphical illustration of the problem above showing the direction of all forces.
Kate Reply
To solve this problem, we need to first find the net force acting on charge q_{2}. The magnitude of the force exerted by q_{1} on q_{2} is given by F=\frac{kq_{1}q_{2}}{r^{2}} where k is the Coulomb constant, q_{1} and q_{2} are the charges of the particles, and r is the distance between them.

What is the direction and net electric force on q_{1}= 5µC located at (0,4)r due to charges q_{2}=7mu located at (0,0)m and q_{3}=3\mu C located at (4,0)m?

what is a capacitor?
Raymond Reply
Capacitor is a separation of opposite charges using an insulator of very small dimension between them. Capacitor is used for allowing an AC (alternating current) to pass while a DC (direct current) is blocked.

which has a higher temperature, 1cup of boiling water or 1teapot of boiling water which can transfer more heat 1cup of boiling water or 1 teapot of boiling water explain your . answer
Ramon Reply
I believe temperature being an intensive property does not change for any amount of boiling water whereas heat being an extensive property changes with amount/size of the system.
Someone
Scratch that
Someone
temperature for any amount of water to boil at ntp is 100⁰C (it is a state function and and intensive property) and it depends both will give same amount of heat because the surface available for heat transfer is greater in case of the kettle as well as the heat stored in it but if you talk.....
Someone
about the amount of heat stored in the system then in that case since the mass of water in the kettle is greater so more energy is required to raise the temperature b/c more molecules of water are present in the kettle
Someone

Two bodies attract each other electrically. Do they both have to be charged? Answer the same question if the bodies repel one another.
JALLAH Reply
No. According to Isac Newtons law. this two bodies maybe you and the wall beside you. Attracting depends on the mass och each body and distance between them.
Dlovan
Are you really asking if two bodies have to be charged to be influenced by Coulombs Law?

What is specific heat capacity
Destiny Reply
Specific heat capacity is a measure of the amount of energy required to raise the temperature of a substance by one degree Celsius (or Kelvin). It is measured in Joules per kilogram per degree Celsius (J/kg°C).
