Ware noord

Ware noord

  • Die noordekant van ‘n kaart word WARE NOORD genoem. Dit wys altyd na die Noordpool. Gebruik julle aardbol en kyk of julle die Noordpool kan vind.
  • Op enige goeie kaart moet daar rigting aangedui word. Dit word gedoen deur ‘n pyl wat noord wys op die kaart te teken.

WN = Ware Noord

  • Maak jou atlas oop by ‘n kaart van Suid-Afrika. Kyk waarheen die kaart se ware noordpool wys. Draai nou weer almal julle banke so dat julle in die rigting van Noord kyk.
  • Nou is jou kaart GEORIËNTEER Wat beteken dié groot woord?
  • Dit beteken maar net dat die werklike rigting dieselfde is as die rigting op die kaart.

Aktiwiteit 1

Om die ligging van ‘n plek op ‘n kaart te bepaal [lu 1.4]

Soek die ligging van Johannesburg op die kaart van Suid-Afrika voor jou en beantwoord die volgende vrae:

1. In watter rigting lê die volgende stede vanaf Johannesburg?

a) Pretoria

b) Bloemfontein ...........................................................................................


Party van julle sukkel om die plekke op die kaart te kry en die opvoeder kan nie almal gelyktydig help nie.

Maar daar is ‘n makliker manier!

Jou opvoeder gaan ‘n MUURKAART teen die muur ophang wat net soos joune in die atlas lyk.

Op hierdie muurkaart word ware noord ook aangedui. Nou kan jou opvoeder op die muurkaart wys waar die plekke geleë is en jy kan dan op jou atlaskaart kyk en die plekke makliker vind.

Omdat die muurkaart teen die muur hang (vertikaal), lyk dit asof Noord nou na "bo" wys.

Dit is egter nie waar nie.

Onthou hoe julle die hoofrigtings in julle klaskamer gemerk het. As jy so draai dat jy NOORD kyk, is

- Suid agter jou,

- Oos is regs (waar die son opkom), en

- Wes is links (waar die son ondergaan).

Gebruik ALTYD die regte rigtingname !


Leeruitkoms 1: aardrykskundige ondersoek

Die leerder is in staat om ondersoekvaardighede te gebruik om aardrykskundige en omgewingsbegrippe en -prosesse te ondersoek.


Dis duidelik wanneer die leerder

1.4 plekke se ligging vind deur ‘n eenvoudige ruitenetverwysingstelsel en rigting te gebruik.


Om die ligging van ‘n plek op ‘n kaart te bepaal

a) NO

b) SW

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.

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?
