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 lberoepsmoontlikhede ondersoek; en

12. entrepreneursgeleenthede te ontwikkel.

Integrasie van Temas:

  • Inklusiwiteit: Ons kan almal by mekaar leer. Die een kultuur kan die ander stimuleer en verryk. Wys hoe dit gedoen kan word.
  • Menseregte: Leerders moet die verskille tussen hulle respekteer. Besluit hoe ons verskil en wat ons verskillend maak. Tog is elkeen net so menswaardig soos enige ander leerder in die klas.
  • ‘n Gesonde omgewing: Blomme verryk ons omgewing. Gesonde kos gee vir ons gesonde liggame. Bespreek gesonde, voedsame kossoorte en maak ‘n lys daarvan. Doen navorsing om vas te stel of die leerders in jou klas gesonde kosse eet.
  • Getalbegrip en aantel tot 200 en verder word geoefen.
  • Ewe en onewe getalle, afronding van getalle en plekwaardes word hersien.
  • Die tafels van 4 en 3 en deelaktiwiteite word ingesluit.
  • Optelling met herbenoeming word geoefen.
  • Verdubbeling met herbenoeming.
  • Samestellings van 19.
  • Die volgende aktiwiteite is ook ingesluit: massa, inhoud, breuke en afstand.
  • Leerders maak kennis met die volgende voorwerpe: piramides, prismas en silinders,
  • Die aansigvorms van hierdie 3-D vorms word bespreek en vergelyk.

LU 1.3 LU 1.9
  • Hier is ‘n mini-pylskyf.

  • Jy het 2 pyltjies.

Op watter getalle moet jy beland om ‘n totaal van 19 te maak?

  • Skryf die getalsinne hier.

__________________ = 19 __________________ = 19

__________________ = 19 __________________ = 19

__________________ = 19 __________________ = 19

__________________ = 19 __________________ = 19

__________________ = 19 __________________ = 19

  • Wat sou gebeur as jy 3 pyltjies gehad het?

__________________ = 19 __________________ = 19

__________________ = 19 __________________ = 19

__________________ = 19 __________________ = 19

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 1.2: Dit is duidelik wanneer die leerder aan en terug tel;

Assesseringstandaard 1.3: Dit is duidelik wanneer die leerder getalsimbole van 1 tot minstens 200 ken en lees en skryf getalname van 1 tot minstens 100;

Assesseringstandaard 1.8: Dit is duidelik wanneer die leerder die gepaste simbole in berekeninge gebruik om probleme op te los:

Assesseringstandaard 1.9: Dit is duidelik wanneer die leerder hoofberekeninge uitvoer;

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 2.2: Dit is duidelik wanneer die leerder eenvoudige getalreekse kopieer en uitbrei tot minstens 200.

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.
