Grade 5

Population: distribution and density

Module 24

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:

Activity 1:

To calculate the population density of south africa

[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 .

Activity 2:

To do a census and represent it graphically

[lo 1.3; 1.7]

Do a census in your class/grade.

  • 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.

Activity 3:

To interpret and show the human population numbers graphically

[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.


LO 1


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].

can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
okay, so you have 6 raised to the power of 2. what is that part of your answer
I don't understand what the A with approx sign and the boxed x mean
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
I'm not sure why it wrote it the other way
I got X =-6
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
oops. ignore that.
so you not have an equal sign anywhere in the original equation?
is it a question of log
I rally confuse this number And equations too I need exactly help
But this is not salma it's Faiza live in lousvile Ky I garbage this so I am going collage with JCTC that the of the collage thank you my friends

algebra 2 Inequalities:If equation 2 = 0 it is an open set?
Kim Reply
or infinite solutions?
The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

I start with an easy one. carbon nanotubes woven into a long filament like a string
many many of nanotubes
what is the k.e before it land
what is the function of carbon nanotubes?
I'm interested in nanotube
what is nanomaterials​ and their applications of sensors.

Yes, Nanotechnology has a very fast field of applications and their is always something new to do with it...
Himanshu Reply
good afternoon madam
what is system testing
what is the application of nanotechnology?
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
anybody can imagine what will be happen after 100 years from now in nano tech world
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
silver nanoparticles could handle the job?
not now but maybe in future only AgNP maybe any other nanomaterials
I'm interested in Nanotube
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
can nanotechnology change the direction of the face of the world

At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.

the Beer law works very well for dilute solutions but fails for very high concentrations. why?
