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: Vriende
  • Inklusiwiteit: Alhoewel elkeen van ons uniek is, is daar baie ooreenkomste; karaktereienskappe, sport, opvoeding ens.
  • Sosiale Geregtighede: Bespreek vriende se gedrag teenoor mekaar.
  • n Gesonde Omgewing: Wat is ons plig as aardbewoners om ons omgewing skoon te hou?

Opvoeder se bladsy

Getalkombinasies

  • Gebruik flitskaarte met +1, -1, +2, -2 getalsinne. Flits en assesseer of die leerders die antwoorde redelik vinnig kan gee, en of hulle nog steeds tellers ens. nodig het.
  • Doen ‘n voorbeeld van die versteekte prentjie (bladsy 16)

Inhoud

Aktiwiteit: getalkombinasies [lu 1.9, lu 1.11, lu 1.12, lu 3.1]

Smarties op ‘n bord.

  • Ek voeg nog drie by elke bord.

  • Sisulu het 6 smarties. Hy eet drie. Nou het hy ........... smarties oor.
  • Des het drie smarties geëet. Hy het 4 smarties oor. Hy het ........... smarties aan die begin gehad.
  • Sê of wys hoe jy die som gedoen het.
LU 1.9 LU 1.11

Meer pret!

  • Gebruik die antwoorde om ‘n rooi kolletjie te teken. Verbind die kolletjies om ‘n prentjie te maak.

Wat het jy geteken? ____________________________________________________

  • Volg die pad na Susan se huis.

  • Sê die antwoorde vinnig vir ‘n maat. Skryf dan die antwoorde.

4 + 3 = . 5 - 3 = . 9 - 3 = .

3 + 3 = . 6 + 1 = . 7 + 2 = .

7 - 2 = . 1 + 3 = . 8 - 3 = .

  • Kies een en kleur in.

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 wat die volgende behels:

1.9.1 optelling en aftrekking van getalle tot minstens 20;

1.9.2 vermenigvuldiging van heelgetalle met oplossings tot minstens 20;

Assesseringstandaard 1.11: Dit is duidelik wanneer die leerder eie oplossings vir probleme verduidelik.

Leeruitkomste 3: Die leerder is in staat om eienskappe van en verwantskappe tussen tweedimensionele vorms en driedimensionele voorwerpe in 'n verskeidenheid oriëntasies en posisies te beskryf en voor te stel.

Assesseringstandaard 3.1: Dit is duidelik wanneer die leerder tweedimensionele vorms en driedimensionele voorwerpe in die skoolomgewing en in prente herken, identifiseer en benoem, insluitend:

3.1.1 bokse (prismas) en balle (sfere);

3.1.2 driehoeke en reghoeke;

3.1.3 sirkels.

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.

what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.

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.

Do you know which machine is used to that process?

In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
Azam
anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
Hello
Uday
I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
