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 lberoepsmoontlikhede ondersoek; en

12. entrepreneursgeleenthede te ontwikkel.

Integrasie van Temas:

  • Inklusiwiteit: Elke leerder in ‘n klas verdien om voor ‘n uitdaging geplaas te word. Spesiale kreatiwiteit werk moet nie slegs aan skrander leerders opgedra word nie. Geleenthede vir uitbreiding, eksperimentering en ontdekking moet aan almal in die klas gebied word. Dit sal leerders aanmoedig om nuwe metodes uit te probeer, om by eweknieë te leer en om risiko’s te neem. Hou klein groepbesprekings oor die werklikheid daarvan om werkopdragte te doen wat ons forseer om te dink.
  • Praktiese ervaring met halwes en kwarte word gedoen.
  • Getalbegrip word uitgebrei verder as 200 en telpatrone word beklemtoon.
  • Leerders word versigtig gelei om die afronding van getalle tot die naaste veelvoud te begryp.
  • Samestellings van 17, 18 en 20 word bekend gestel.
  • Getalwaardes en plekwaardes word met diagramme aangeleer.
  • Die vermenigvuldigingstafels van 10 en 5 word opgebou.
  • Leerders kan hulle eie patrone ontwerp en speletjies word ingesluit om getalfeite te konsolideer.
  • Leerders ontwerp diere met vorms deur hulle verbeelding te gebruik.

Inhoud

Aktiwiteit: breuke met vierkante [lu 1.7, lu 1.10, lu 4.1]

Breuke met vierkante

  • Neem 'n vel papier.
  • Sorg dat die sye almal ewe lank is.
  • Hierdie vorm word 'n vierkant genoem.
  • Vou die vierkant in die helfte. Vou die papier weer oop.
  • Knip al op die voulyn.
  • Nou is daar twee stukke papier wat ewe groot is.
  • Een stuk word 'n halwe genoem.
  • Twee halwes maak een hele.
  • Neem 'n ander vierkant.
  • Vou dit op 'n ander manier in die helfte, bv.

LU 1.7

Breuke met driehoeke en reghoeke

  • Neem 'n vel papier wat soos 'n driehoek lyk.
  • Vou dit in die helfte en knip dit op die voulyn.
  • Merk elke stuk "een halwe".
  • Twee halwes maak 1 ________________________________________
  • Doen dieselfde met 'n vel papier wat soos 'n reghoek lyk.
  • Vou en knip die reghoek op verskillende maniere.
  • Twee halwes maak 1 ________________________________________
  • Trek sirkels om die vorms waarvan 1 helfte ingekleur is.

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.
