Grade 4

HOW PEOPLE MAKE A LIVING

Module 1

ESSENTIAL NEEDS AND LUXURIES

Activity 1

To draw up a list of essential things to survive [LO 1.1]

While travelling over North Africa the aeroplane in which you are develops engine trouble. The pilot makes an emergency landing and the aeroplane comes to a standstill against a high dune in die Sahara Desert. Nobody is seriously injured, but the passengers and the flight crew immediately realise that it is necessary to plan the use of their supplies carefully to ensure their survival.

  1. Supposing that you and your friends are among the passengers, draw up a list of things that you will need to survive in the desert for a few days.

Activity 2

To identify luxuries [LO 1.1]

The things you have considered are things you will need to survive from day to day. These are our essential needs , but they only form a small part of all the things we might buy from day to day. If your mother allowed you to go to the local supermarket with R200 in pocket money, your interests would be very different.

  1. Are you able to list some things that you would buy with your pocket money?

This list includes examples of luxury items. Luxuries are articles that you do not need for survival. They are things that are nice to have and give you the pleasure of feeling spoilt.

Activity 3

To become aware of the difference between essentials and luxuries [LO 1.1]

(c) List the articles below according to the table:

running shoes

wristwatch

1 litre of milk

toothbrush

thick-soled sandals

golden earrings

headache tablets

skateboard

shampoo

cardigan

house

new car

water

sweets

swimming pool

(d) Group work.

You participate in sport after school and you have R5 to spend at the tuck shop after the practice session. You have a choice of the following:

fruit juice R2,50

ice cream R4,50

a packet of sweets R2,00

potato chips R2,50

2 suckers R1,00

3 cookies R1,00

What would you choose?

Are the items you chose an essential need? Could you survive without them?

Do you think people would be satisfied if only their essential needs were met every day? Why do you say this?

Activity 4

To identify essential articles for daily use [LO 1.1]

  1. Make a list of essential articles without which you cannot cope for one day:

The needs of all people are not the same. The Khoi and the San people lived under conditions that were different from those of modern people. With a friend make a list of the basic needs of a Khoi or San family.

Assessment

LEARNING OUTCOME 1: THE ECONOMIC CYCLE

The learner will be able to demonstrate knowledge and understanding of the economic cycle within the context of “the economic problem”.

Assessment Standard

We know this when the learner:

1.1 describes the roles of members of households as consumers and producers in the “need satisfaction” process.

Memorandum

Page 1

(a) Based on a sketch in which an emergency situation is depicted, learners must be able to distinguish between essential needs and luxuries.

Page 2

(b) A familiar situation is used to illustrate that people strive towards satisfying far more than basic needs only.

Page 3

  1. Everyday articles are classified as either essential needs or luxuries.

Page 4

(d) Learners identify the essential articles in their everyday existence.

(e) Draw a comparison between what we regard as basic needs and the basic needs of the Khoina.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
