Memorandum

Kritieke- en ontwikkelings uitkomste

Die leerders moet uiteindelik kan:

1. probleme identifiseer en oplos, en ook besluite neem deur kritiese en kreatiewe denke;

2. doeltreffend saam met ander lede van ‘n span, groep, organisasie en gemeenskap werk;

3. hulself en hul aktiwiteite verantwoordelik en doeltreffend bestuur;

4. inligting versamel, ontleed, organiseer en krities evalueer;

5. doeltreffend kommunikeer deur middel van visuele, simboliese en/of taalvaardighede in verskillende vorme;

6. wetenskap en tegnologie doeltreffend en krities gebruik deur verantwoordelikheid teenoor die omgewing en die gesondheid van ander te toon;

7. begryp dat die wêreld ‘n stel verwante stelsels is waarin probleme nie in isolasie opgelos word nie;

8. na te dink oor en ondersoek te doen na ‘n verskeidenheid strategieë om doeltreffender te leer;

9. as verantwoordelike burgers aan die lewe van die plaaslike, nasionale en wêreldgemeenskap deel te neem;

10. in verskeie sosiale kontekste kultureel en esteties sensitief te wees;

11. opvoedings- en beroepsmoontlikhede ondersoek; en

12. entrepreneursgeleenthede te ontwikkel.

Integrasie van Temas:

  • ‘n Gesonde Omgewing: Ons paaie word deur baie voertuie gebruik en dit is ‘n belangrike oorsaak van besoedeling. Bespreek. Veiligheid op ons paaie is essensieel. Leerders moet padreëls en veiligheidsreëls wat deur die skool en die owerhede ingestel is, gehoorsaam. Bespreek wat gedoen kan word om die leerders se veiligheid na en van die skool te verseker. Plante en blomme versier ons omgewing en moet beskerm word. Moenie hulle vernietig nie.
  • Inklusiwiteit: Mens, dier en plant is van mekaar afhanklik om te oorleef. Bespreek en gee voorbeelde.
  • Voertuie maak ‘n belangrike deel van leerders se ervarings uit. Aktiwiteite soos tel tot by 150, ‘n grafiek wat afstande en voertuie bepaal, asook die uitbreiding van samestellings van 16, word gebruik.
  • Voorwerpe tot 50 word geskat, gegroepeer en getel.
  • Die vermenigvuldigingstafel van 2 word bekend gestel en optelling en aftrekking van 6, 7, 8 en 9 word ingesluit.
  • Vorms word geïdentifiseer en gesorteer deur hulle in te kleur.

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 1.9: Dit is duidelik wanneer die leerder hoofberekeninge uitvoer;

1.9.2 vermenigvuldiging van heelgetalle met oplossings tot minstens 20;

Assesseringstandaard 1.10: Dit is duidelik wanneer die leerder die volgende tegnieke gebruik:

1.10.2 verdubbeling en halvering.

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.
