Module 6

Probleemoplossing

VAN VOOR BLINK, MAAR VAN BINNE STINK!

('n Uittreksel uit "Skolenuus", 'n koerant wat landswyd versprei word)

Ek moes 'n pakkie boeke by 'n bekende skool in 'n redelik gegoede woonbuurt gaan afgee. Die skool se buitekant was indrukwekkend: pure pilare, groot vensters en swaar deure. Die groot vensters het nie in die son geskitter nie. Die leë koeldrankblikkies op die vensterbanke het wel! Die vensters was vuil en vol vatmerke. Binnekant het hierdie neiging voortgeduur. Die trappe was vuil en versier met leë blikkies, plastieksakkies, taai lekkergoedpapiere. Dit was stowwerig en van die afval en merke het gelyk asof hulle ou burgers daar was. Binne die klas waar ek die boeke moes afgee, het die tafels sonder plan rondgestaan en party stoele het op hul sye gelê. Die vloer was weer eens versier met stukkies afvalpapier en leë plastieksakkies. Van die stoele was stukkend en van die tafels was bekrap met allerhande slagspreuke en obsene woorde. Ek het my pakkie neergesit en gewonder of die toestand van die plek die toestand van die mense wat hierdie plek gebruik se gedagtes weerspieël?

(Brief verkort - Red.)

Jou beurt!

Wat nou? Nou is dit julle beurt om die stappe te volg om te sien of julle met werkbare oplossings kan help om die probleem hierbo op te los.

1. Wat is die regte of werklike probleem?

2. Watter moontlikhede en oplossings is daar?

3. Watter idees mag werk? (Watter kriteria word gebruik?)

4. Wat is die plan?

Hier behoort die volgende vrae beantwoord te word:

  • Wie gaan wat doen?
  • Wanneer gaan wat gedoen word?
  • Hoe gaan die onkostes gedek word?
  • Hoe sal ons weet dat die plan 'n sukses was?

5. Hoe gaan ons ander oortuig?(Dis belangrik om die samewerking van ander mense te hê.)

Daarna...

Deel al die idees met mekaar. Is daar enige idees wat julle by julle betrokke skool kan gebruik?

Assessering

Leeruitkomstes(LUs)
LU 3
PERSOONLIKE ONTWIKKELINGDie leerder is in staat om verworwe lewensvaardighede te gebruik om persoonlike potensiaal te verwesenlik en uit te brei ten einde doeltreffend op uitdagings in sy of haar wêreld te reageer
Assesseringstandaarde(ASe)
Dit is duidelik wanneer die leerder:
3.3 gepas op emosies in uitdagende situasies reageer.
3.4 verduidelik wat uit ‘n uitdagende persoonlike interaksie geleer is deur krities oor eie optrede te besin;
3.6 eie toepassing van probleemoplossings-vaardighede in ‘n uitdagende situasie krities evalueer.

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.
Tarell
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?

what is the application of nanotechnology?
Stotaw
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
