Geography

Grade 5

Resources

Module 16

Natural resources: plants

Make use of what you have learnt previously to try to complete the following definition concerning NATURAL RESOURCES.

People need natural resources such as plants,......................................,

soil, ........................................... and water to survive. All of this is obtained from

nature. Examples of fossil fuels are gas and coal while minerals such as salt, rocks, gold, silver, iron and calcium are formed in the earth by nature.

Activity 1:

To identify resources

[lo 1.3]

Study the sketch of a production line for the manufacturing of cars and list the natural resources that you think may be necessary for the production of a modern motor vehicle.

Natural resources:

Are you able to think of other resources besides natural resources that are also

utilised in the production of cars? (Take another look at the sketch on page 1.)

Utilisation of natural resources by our predecessors

Our predecessors and the people of early civilisations were very aware of their dependence on natural resources. From the earliest times, people settled where they had access to food and water. They lived as nomads, wandering around in search of grazing, food and water. In time they became farmers and settled down for longer periods of time in places where the natural resources were adequate. Eventually people discovered mineral resources, e.g. iron and copper. This made it possible to produce objects for adorning themselves and for domestic wares, as well as weapons like arrowheads that helped them to hunt animals for food and defend themselves against their enemies.

Although we are less aware of our dependence on natural resources, we do need many different resources for our survival.

  1. Plants as a natural resource

Activity 2:

To listen to the uses of natural resources

[lo 1.2; 1.3]

Competition time! See who is able to draw up the longest list of uses of plants as a natural resource .

Forestry as a natural resource

Forestry is the important resource that enables you to write and communicate successfully day after day. For this, thousands of trees are felled every day, merely to produce enough paper to produce daily newspapers. Although people plant plantations, they are better suited to some climatic regions than to others and are therefore spread out across the country.

Forestry in South Africa and Namibia

Activity 3:

To investigate products that are derived from wood

[lo 1.1]

  • Investigate every room in the school through which you move and make a list of all the products/articles that are made of wood.

Assessment

LO 1

GEOGRAPHICAL ENQUIRY

The learner will be able to use enquiry skills to investigate geographical and environmental concepts and processes.

We know this when the learner:

1.1 with guidance, selects and uses sources of useful geographical information [finds sources];

  • distinguishes between facts and opinions [works with sources];
  • categorises information [works with sources];
  • uses an index to find places on global atlas maps [works with sources];

1.6 identifies and explores possible solutions to problems [answers the question];

1.7 demonstrates knowledge and under-standing of the issue through projects, discussion, debate and charts [communicates the answer].

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.

is Bucky paper clear?
CYNTHIA
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
NANO
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.
Harper
