Inhoud

Aktiwiteit: getallepatrone (module toets) [lu 2.1, lu 2.3, lu 2.4]

8. probleem

Werk saam met ’n maat. Vind die oplossing vir die volgende probleem deur van ’n getallepatroon gebruik te maak.

’n Boer het besluit om met een paar konyne te begin boer in Januarie. Elke paar konyne skenk vanaf twee maande na geboorte maandeliks geboorte aan ’n nuwe paar konyne.

Hoeveel pare konyne sal die boer aan die einde van Desember daardie jaar hê?

(Wenk: teken ’n diagram).

Assessering

Leeruitkomste 2: Die leerder is in staat om patrone en verwantskappe te herken, te beskryf en voor te stel en probleme op te los deur algebraïese taal en vaardighede te gebruik.

Assesseringstandaard 2.1: Dit is duidelik wanneer die leerder numeriese en meetkundige patrone ondersoek en uitbrei op soek na ‘n verwantskap of reëls, insluitend patrone.

Assesseringstandaard 2.3: Dit is duidelik wanneer die leerder voorstellings maak van en verwantskappe tussen veranderlikes gebruik sodat inset- en/of uitsetwaardes op ‘n verskeidenheid maniere bepaal kan word.

Assesseringstandaard 2.4: Dit is duidelik wanneer die leerder wiskundige modelle saamstel wat oplossings vir probleemsituasies voorstel, beskryf en voorsien, en verantwoordelikheid toon teenoor die omgewing en die gesondheid van ander (insluitend probleme binne menseregte-, sosiale, ekonomiese, kulturele en omgewingskontekste).

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.
Tarell
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.
