Inhoud

Aktiwiteit: om kontekste te gebruik wat ekonomiese kwessies aanraak [lu 1.6]

1. Betaalstrokies is deel van ons lewens. Waar ons ookal koop en betaal, kry ons so ‘n bewysstrokie. Kom ons bekyk ‘n paar van naderby!

Jou opvoeder sal vir jou die nodige folio vir die taak voorsien.

Deel in groepe van drie. Maak minstens drie betaalstrokies (julle mag meer ook kry!) van verskillende winkelgroepe in jul omgewing bymekaar en vergelyk hul ten opsigte van die volgende:

1.1 Uitleg: Waar staan die naam van die winkelgroep?

Is daar ‘n adres? Waar staan dit?

Is daar ‘n telefoonnommer? Waar staan dit?

Is daar ‘n faksnommer? Waar staan dit?

1.2 Wat, behalwe bogenoemde, word alles op elke betaalstrokie aangedui?

1.3 Is daar enige ooreenkomste tussen die verskillende betaalstrokies? Indien wel, wat?

1.4 Is daar enige verskille tussen die verskillende betaalstrokies? Indien wel, wat?

1.5 Watter betaalstrokie is volgens julle die beste? Motiveer jul antwoord.

ASSESSERING: BETAALSTROKIES
1 2 3 4
Werk saam met ander Werk nie effektief saam nie Werk saam, maar moet baie aangepraat word Werk saam, maar luister nie na menings van groeplede nie Werk pragtig saam en luister na voorstelle van groeplede
Netheid en organisasie Werk is slordig en ongeorganiseerd Georganiseerd, maar moeilik leesbaar Netjies en georganiseerd, maklik leesbaar Netjiese, duidelik uiteengesitte werk; duidelik leesbaar
Volledigheid Minder as 3 betaalstrokies. Nie alle vrae beantwoord nie Baie van die inligting ontbreek Slegs enkele vrae is nie beantwoord nie Opdrag volledig uitgevoer

UITDAGING!

Kyk of jy die volgende lettersom kan oplos:

T A K

+ T A K

P O T

Elke letter verteenwoordig ‘n ander syfer van 1 tot 9. Vind waardes vir A, K, O, P en T.

(Daar is 13 oplossings!)

Assessering

Leeruitkomste 1: Die leerder is in staat om getalle en die verwantskappe daarvan te herken, te beskryf en voor te stel, en om tydens probleemoplossing bevoeg en met selfvertroue te tel, te skat, te bereken en te kontroleer.

Assesseringstandaard 1.6: Dit is duidelik wanneer die leerder probleme in konteks oplos, insluitend kontekste wat gebruik kan word om ‘n bewustheid van ander leerareas, asook van menseregte-, sosiale, ekonomiese en omgewingskwessies, te bevorder:

1.6.1 finansiële kontekste (insluitend koop en verkoop, wins en verlies, en eenvoudige begrotings).

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.
