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.

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.

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.

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.

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.
