Aardrykskunde

Graad 5

Kaartwerk

Module 1

Kaartsimbole en kaarte

1.Wat is ’n simbool?

  • Onthou jy nog dat voorwerpe anders lyk as jy hulle van die kant af sien as wanneer jy hulle van bo af sien?
  • So, byvoorbeeld, is padtekens prentjies van voorwerpe. Ons noem dit SIMBOLE. ‘n Kaart is eintlik ook maar net ‘n prentjie van wat jy ver onder jou sien as jy hoog bo uit die lug afkyk na die grond.
  • Oor baie jare het die mense wat kaarte teken, simbole vir elke afsonderlike voorwerp ontwerp. Hierdie simbole word deur almal erken en het dus dieselfde betekenis vir almal, anders gaan niemand verstaan wat op ‘n kaart geteken is nie.
  • Hierdie erkende simbole word dan onderaan kaarte aangedui en word die SLEUTEL van die kaart genoem.

Aktiwiteit 1:

Om die posisie van plekke op 'n kaart aan te dui

[lu 1.4]

Kom ons kyk na die kaart van die dorpsplan waar Tom woon en probeer dan die vrae wat volg, beantwoord.

TOM SE DORPSPLAN

Sleutel Berg/heuwelBomePaaieGeboueSportvelde

Gestel jy staan by Tom se skool. In watter rigting lê die volgende?

  • die heuwel
  • die Munisipale sportvelde
  • die sportstadion
  • die klubhuis

Jou onderwyser kan vir jou ‘n kaart van jou eie dorp uitdeel. Voorbeelde van sulke dorpsplanne is gewoonlik by jou dorp se munisipaliteit, toeristeburo of die petrolvulstasies beskikbaar.

Aktiwiteit 2:

Om 'n eenvoudige sketsplan te teken

[lu 1.4]

Gebruik nou die kennis wat jy sover opgedoen het en teken ‘n eenvoudige sketsplan van hoe jy van die skool na jou huis/jou vriend se huis moet ry / loop.

Onthou:

  • gebruik kaartsimbole met ‘n duidelike sleutel;
  • dui straatname aan waar bekend;
  • jou plan moet ‘n duidelike opskrif hê;
  • dui die roete met rooi aan.

Assessering

LU 1

AARDRYKSKUNDIGE ONDERSOEK

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

Dit is duidelik wanneer die leerder:

  • bronne met nuttige aardrykskundige inligting kan kies en gebruik;
  • inligting kategoriseer;
  • sketskaarte en/of planne na aanleiding van veldwaarnemings en afmetings teken;
  • ‘n indeks gebruik om plekke op wêreldatlaskaarte te vind;

deur projekte, bespreking, debat en diagramme, kennis en begrip van die vraagstuk toon [dra die antwoord oor].

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.

Do you know which machine is used to that process?

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
Prasenjit
can nanotechnology change the direction of the face of the world
