Map work

Module 3

The compass

  • The compass is an instrument used to determine direction.A Compass
    If your school owns a compass, take it outside to the sports field and try to determine north.

Activity 1

To do research on the compass [lo 1.1]

Do RESEARCH on the compass as an instrument for determining direction. Write down your information and REPORT what you have found.

Do the following:

  1. Visit a library and find at least two books (sources) containing information on the topic. Write down their names.
  2. Read the first source and write down the information under SOURCE 1.

3. Now read the second source and write down the additional information that was NOT mentioned in SOURCE 1 under SOURCE 2.

  1. Use the information from both sources to write a paragraph or two about the compass.
Source 1: ……………………………………………………………………….…………………………………………………………………
……………………………………………………………………….……………………………………………………………………….……………………………………………………………………….………………………………………………………………………..………………………………………………………………………..
Source 2: ……………………………………………………………………….…………………………………………………………………
……………………………………………………………………….……………………………………………………………………….……………………………………………………………………….……………………………………………………………………….……………………………………………………………………….

Activity 2

To find answers for questions on directions [lo 1.6]

Here are a few brainteasers! Try to find answers and to come to a conclusion by talking to one another.

1. In which direction do swallows migrate at the beginning of the winter in South Africa? Do you know why?

……………………………………………………………………………………..

…………………………………………………………………………………….

…………………………………………………………………………………….

2. Why do South Africans prefer that the windows of their houses be situated on the north side of the building?

……………………………………………………………………………………..

……………………………………………………………………………………..

…………………………………………………………………………………………

…………………………………………………………………………………………

When working with maps and direction, you should always know where NORTH is.

Assessment

Learning outcome 1: geographical enquiry

The learner will be able to use enquiry skills to investigate geographical and

environmental concepts and processes.

Assessment standard

We know this when the learner:

1.1 identifies information from various sources (maps, atlases, books) [finds sources];

1.6 uses information from sources (including own observations) to answer questions about people and places (e.g. ‘Why is it like that?’) [answers the question].

Questions & Answers

do you think it's worthwhile in the long term to study the effects and possibilities of nanotechnology on viral treatment?

how to know photocatalytic properties of tio2 nanoparticles...what to do now
Akash Reply
it is a goid question and i want to know the answer as well

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.
Tarell
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?
CYNTHIA
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
Do you know which machine is used to that process?

what is system testing?
AMJAD
preparation of nanomaterial
Victor Reply
Yes, Nanotechnology has a very fast field of applications and their is always something new to do with it...
Himanshu Reply
good afternoon madam
AMJAD
what is system testing
AMJAD
what is the application of nanotechnology?
Stotaw
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
Azam
anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
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
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
Hello
Uday
I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
