## Describing concepts

Population: The people who live in a specific area (town/region/city/province/country/part of the world).

Population Distribution: Where people live within a specific area.

Population Density: How many people live in a specific area.

To work out the density of population of a region/country, you take the total population of the region/country and divide it by the total area (in square kilometres) of the region/country. Your answer should indicate the number of people on average that live in a square kilometre of the region/country.

One square kilometre is a square area measuring one kilometre by one kilometre:

DENSELY POPULATED ………………….. SPARSELY POPULATED

## [lo 1.1]

Use the following statistics, your pocket calculator and the formula above to calculate the population density of South Africa and India respectively. Round off your answer to the nearest integer.

Population of South Africa (according to 1996 census): 41 million (rounded off).

Area of South Africa: 1 219 090 km 2 (rounded off).

Population of India (according to 2001 census): 1 029 million (rounded off).

Area of India: 3 174 723 km 2 (rounded off).

What conclusion do you come to if you compare the population numbers of South Africa and India?

It is important to remember that the above numbers are only average numbers. There are areas in South Africa (and India) where more or fewer people live per km 2 .

## [lo 1.3; 1.7]

• Compile a list of approximately 10 questions that are found on a census form.e.g. How old are you?
 0 – 20 20 – 30 30 – 50 50+

In what type of house do you live?

 flat house on separate plot townhouse other

Which of the following articles are found in your home?

 television radio microwave computer camera telephone Cell phone satellite television internetetc.
• Your questions must be aimed at the general public, and not only at the local inhabitants.
• After the class has completed the census, process the information and put it in writing. E.g. 30% have a television set / 28% has access to the internet / 90% have cellular phones, etc.
• Illustrate one of the questions by means of a pie graph.

## [lo 1.7]

• The following numbers represent the size of the different population groups in South Africa according to the census information of 1996.
 Total population: 40,6 million Africans: 31,1 million Whites: 4,4 million Coloureds: 3,6 million Indians: 1,1 million Other: 0,4 million

Illustrate the population composition by means of a graph.

## 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];

1.2 distinguishes between facts and opinions [works with sources];

1.3 categorises information [works with sources];

1.4 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].

how can chip be made from sand
is this allso about nanoscale material
Almas
are nano particles real
yeah
Joseph
Hello, if I study Physics teacher in bachelor, can I study Nanotechnology in master?
no can't
Lohitha
where is the latest information on a no technology how can I find it
William
currently
William
where we get a research paper on Nano chemistry....?
nanopartical of organic/inorganic / physical chemistry , pdf / thesis / review
Ali
what are the products of Nano chemistry?
There are lots of products of nano chemistry... Like nano coatings.....carbon fiber.. And lots of others..
learn
Even nanotechnology is pretty much all about chemistry... Its the chemistry on quantum or atomic level
learn
da
no nanotechnology is also a part of physics and maths it requires angle formulas and some pressure regarding concepts
Bhagvanji
hey
Giriraj
Preparation and Applications of Nanomaterial for Drug Delivery
revolt
da
Application of nanotechnology in medicine
has a lot of application modern world
Kamaluddeen
yes
narayan
what is variations in raman spectra for nanomaterials
ya I also want to know the raman spectra
Bhagvanji
I only see partial conversation and what's the question here!
what about nanotechnology for water purification
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct
Professor
I think
Professor
Nasa has use it in the 60's, copper as water purification in the moon travel.
Alexandre
nanocopper obvius

what is the stm
is there industrial application of fullrenes. What is the method to prepare fullrene on large scale.?
Rafiq
industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong
Damian
How we are making nano material?
what is a peer
What is meant by 'nano scale'?
What is STMs full form?
LITNING
scanning tunneling microscope
Sahil
how nano science is used for hydrophobicity
Santosh
Do u think that Graphene and Fullrene fiber can be used to make Air Plane body structure the lightest and strongest. Rafiq
Rafiq
what is differents between GO and RGO?
Mahi
what is simplest way to understand the applications of nano robots used to detect the cancer affected cell of human body.? How this robot is carried to required site of body cell.? what will be the carrier material and how can be detected that correct delivery of drug is done Rafiq
Rafiq
if virus is killing to make ARTIFICIAL DNA OF GRAPHENE FOR KILLED THE VIRUS .THIS IS OUR ASSUMPTION
Anam
analytical skills graphene is prepared to kill any type viruses .
Anam
Any one who tell me about Preparation and application of Nanomaterial for drug Delivery
Hafiz
what is Nano technology ?
write examples of Nano molecule?
Bob
The nanotechnology is as new science, to scale nanometric
brayan
nanotechnology is the study, desing, synthesis, manipulation and application of materials and functional systems through control of matter at nanoscale
Damian
how did you get the value of 2000N.What calculations are needed to arrive at it
