1. Study Source D. Use information you can derive from it to compile a bar diagram showing the incidence of Aids worldwide. Place the different regions of the world on the horizontal axis.

2. Study Sources B and D. How do the statistics differ with regard to the number of people in the world who have Aids?

3. Refer to question 2. Which of the two would you regard as the more accurate source? Provide reasons for your opinion.

4. Study sources A and B. List at least three results of the Aids epidemic, especially with regard to Africa.

5. Do you agree, with regard to Source A, that the Aids epidemic can affect food production? Provide an explanation, in your own words, of how the epidemic could have an effect on food production:

6. Make use of a map of Africa, the information offered in Source A and any other information that you have obtained and indicate the countries in Southern Africa where there is famine.

Learning outcomes (LOs)
LO 1
Historical investigation The learner is able to use research skills to investigate both the present and the past.
Assessment standards (ASs)
We know this when the learner:
1.1 investigates a topic by asking key questions and identifies a variety of relevant sources to explore this topic [finding sources];
1.2 asks significant questions to evaluate the sources (e.g. to identify bias and stereotypes, omissions and gaps) [working with to sources];
1.3 analyses the information in sources [working with sources];
1.4 presents an independent line of argument in answering questions posed, and justifies (using evidence) the conclusions reached [answering the question];
1.5 communicates knowledge and understanding by constructing own interpretation and argument based on the historical sources; uses information technology where available and appropriate [communicating the answer].
LO 2
Knowledge and Understanding of History The learner is able to demonstrate knowledge and understanding of history.
We know this when the learner:
2.1 places events, people and changes in the periods of history studied within chronological framework [chronology and time];
2.2 identifies categories of cause and effect (e.g. immediate and long-term, direct and indirect) [cause and effect];
2.3 explains and analyses the reasons for and results of events in history [cause and effect];
2.4 recognises that change and development does not always mean progress [change and continuity].
LO 3
Interpretation of History The learner is able to interpret aspects of history.
We know this when the learner:
3.1 understands the contested nature of content, and that historians construct histories when writing about events from the past [source interpretation];
3.2 constructs an interpretation based on sources, giving reasons for own interpretation [source interpretation];
3.3 analyses issues which influence the way history has been written [influences on interpretation];
3.4 explains the ways in which symbols are used to remember events and people from the past, and how oral histories can contribute to our understanding of the symbols [representation of the past].

there is no specific books for beginners but there is book called principle of nanotechnology
what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
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.
what is the actual application of fullerenes nowadays?
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.
what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
carbon nanotubes has various application in fuel cells membrane, current research on cancer drug,and in electronics MEMS and NEMS etc
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.
Do you know which machine is used to that process?
how to fabricate graphene ink ?
for screen printed electrodes ?
What is lattice structure?
s. Reply
of graphene you mean?
or in general
in general
Graphene has a hexagonal structure
