Graad 5

Lewe en lewenswyse

Module 12

Diere en hul vermoë om te beweeg


Om die bewegingsvermoë van enkele soogdiere te ondersoek

[lu 1.2]

Diere moet kan beweeg sodat hulle kos kan bekom. Sommige moet vinnig kan beweeg om ander diere te kan vang. Ander moet weer vinnig kan beweeg om van gevare weg te kom.


Atleties gebou

Jag sy prooi deur dit oor kort afstande te jaag

Vinnigste soogdier op land (spoed ±75 km/h)

Hoekom moet die jagluiperd besonder vinnig wees?


Langste dier op aarde

Lang bene en nek help sodat dier blare en lote van boomtoppe kan vreet.

Opdrag: (groepbespreking)

Bespreek en maak afleidings hoe die bloed dit regkry om die kop te bereik, en waarom ‘n kameelperd sy voorpote wyd uit mekaar plant wanneer hy water drink.


Lang agterbene en kort voorpote.

Beweeg met spronge op agterbene.


LU 1

WETENSKAPLIKE ONDERSOEK Die leerder is in staat om met selfvertroue op weetgierigheid oor natuurlike verskynsels te reageer, en om binne die konteks van wetenskap, tegnologie en die omgewing verbande te ondersoek en probleme op te los.


Dit is duidelik wanneer die leerder:

1.1   ondersoeke beplan;

1.2   ondersoeke uitvoer en data versamel;

1.3       data evalueer en bevindinge kommunikeer;



  1. Moet vinniger wees as bokke wat reeds baie vinnig is.
  2. Die are in die kameelperd se nek het spesiale kleppe wat die bloedvloei na sy kop reguleer omdat die nek so lank is. Wanneer die kameelperd buk om water te drink, sprei hy sy bene sodat daar nie te veel bloed uit die slagare in die brein vloei nie.
  3. Agterbene sterk om oor plante en struike te kan spring en vinnig te kan hardloop om van jagdiere weg te kom.

Mostly, they use nano carbon for electronics and for materials to be strengthened.
is Bucky paper clear?
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 ?

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
