Carrying out a door to door survey

1. Find out how your friends and neighbours commute to school or office
2. Interview at least 10 friends or neighbours who commute to school or office by personal cars
3. Find out if they would be ready to switch to a non-polluting mode of transport, like a bicycle, if their schools or offices are not too far away.
4. Find out if they would like to join a carpool or travel by public transport. Do not forget to mention the advantages of shifting from the use of personal vehicles, such as reduced pollution, savings and companionship.
5. If they are not interested and would like to continue travelling in their private cars, ask them the reasons why would they not make the change.

After collecting all the data, fill in a table like the one given below:

At the end of your survey, find out how many interviewees are now travelling by bicycle, public transport, or car pool and how many have decided not to do so.

1. Number of people interviewed
2. Number of people who commute by private car
3. Number of people who have agreed to change their mode of transport
4. Number of people who now travel by public transport
5. Number of people who have joined a carpool
6. Number of people who are now cycling to work
7. Number of people who have not changed their mode of transport

From page no. 244, your teacher will read out about a presenter discussing three new inventions-The Solerickshaw, the Green Phone and the Solar Water Purifier. As you listen complete the notes given below.

Solar Powered Inventions

1. Features
   1. ..............
   2. ..............
   3. ..............
   4. ..............
2. Designed and developed by .............

You are going to listen to a presenter discussing three new inventions-The  Green Phone . As you listen complete the note given below :

II. Green Phones
1. Blue Earth developed by ...............
(i) back with ..........................
(ii) made from ......................
(iii) C02 emissions monitored by ..............
(iv) fits into  ................

2. Coral 200

(i) powered by ........................
(ii) fits  .....................................
(iii) made by  ........................
(iv) talk time ..................... for every ..................... of sunlight

3. LG

(i) ................ mins, of talk time for  ................  of sunlight
(ii) Bluetooth solar car kit called ...................
(iii) features
(i)  ...................
(ii)  ...................

You are going to listen to a presenter discussing three new inventions- The Solar Water Purifier. As you listen complete the notes given below :

Ill. Solar water purifier
1. First type features
(i) ..........................
(ii) .......................
2. Second type features
(i)........................................
(ii) ....................................
(iii) process of distillation
(a) water heated by .......................
(b) water condenses on .....................................
(c) impurities collected in ..................
(d) water collected in .................
(e) from trough into.......................
(f) germs and bacteria killed by ...........................

You have listened to a presentation on three new inventions. One of them is solar water purifier. The stages of water purifier can be set in a flow-chart. Copy and complete the following flow chart with the stages in their correct order.

1 . impurities of water remain in the box

2 .sun rays heat the water

3 . box filled with unpurified water

4 . solar panel is placed on top of a rectangular shaped box

5 . water condenses on the underside of the solar power

6 . slope of the panel allows water to be collected in the trough

7 . bottles collect water from trough

Now read that portion of the listening text describing the solar distillation system:

You will notice that each sentence is connected with the next one and when we describe a process we use sequence markers like- at first; next; then; now; additionally;

The other commonly used sequence markers are

• first, second, third.....
• at the same time, simultaneously.....
• finally, lastly, in the end, to conclude.....

You may also have observed that the writer has used a combination of Active forms (e.g. the water droplets condense on the underside of the solar panels) to emphasize the ‘doer’ of the action and Passive forms (e.g. the box is filled with unpurified water) when he wants to stress that the action ‘is filled’.

Another feature of a process description is that the writer normally uses the simple present tense, because he describes what always happens in the particular process.

Below is a flow chart describing the process of making rubber. Use it to help you copy and complete the process description that follows it. Remember to use the simple present tense, a mixture of actives and passives, and to add sequence markers where you see

First rubber trees ......... in deep soil. When the trees ..........., fully the........................., the bark of the tree .... and containers ..................... The latex ............... and is ........... to the factory . Here it .................... by treating it with acetic acid. The coagulated mass ................... It is then ...........  into  blocks or............... into sheets. ................................ in a current of warm air.

You have been gifted a new cell phone which is powered by solar energy. Write an email to your friend describing the phone and all its exciting features. You may use the notes that you have made in A7.

While writing this email, remember to:

• Start with writing your friend’s email ID
• Mention the subject clearly
• Begin with Dear ........ followed by a greeting and enquire about their well-being
• Tell them your reason for writing.
