Inhoud

Aktiwiteit: om te teken en sketse te interpreteer [lu 3.7]

1. Kyk goed na die skets van hierdie kubus.

As jy van voor af na die kubus kyk, hoeveel vierkante kan jy nie sien nie?

____________________________________________________________________

2. Kyk na hierdie kubus van die kant af.

2.1 Hoeveel kubusse sien jy?

____________________________________________________________________

2.2 Hoeveel kubusse kan jy nie sien nie?

____________________________________________________________________

3. Teken nou enigeen van hierdie kubusse van bo af.

UITDAGING!

Vra jou opvoeder vir die nodige foliopapier.

Trek jou skoolskoen uit en:

4 Teken dit van bo af.

4 Teken dit van die kant af.

4 Teken dit van onder af.

Tyd vir selfassessering

Lees die kriteria. Hoe voel jy oor die werk wat ons so pas afgehandel het?

HET JY GEWEET?

Wanneer ons ‘n kaart of aanwysings wil lees, kan ons van koördinate gebruik maak!

Dit is belangrik om te onthou dat ons altyd eers die horisontale as sal lees.

In die voorbeeld is punt A se aflesing die paar (1,2).

As jy die paar (3,1) lees, sal jy by B uitkom.

Soms is die rigting ook by, en dan lyk dit so: (1O, 2N) of (3O, 1N).

Assessering

Leeruitkomste 3: Die leerder is in staat om eienskappe van en verwantskappe tussen twee-dimensionele vorms en drie-dimensionele voorwerpe in ‘n verskeidenheid oriëntasies en posisies te beskryf en voor te stel.

Assesseringstandaard 3.7: Dit is duidelik wanneer die leerder sketse van eenvoudige drie-dimensionele voorwerpe vanuit verskillende posisies (perspektiewe) teken en interpreteer.

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.

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
